Congratulations are in order for our very own Matthew Flinders Fellow, Professor Mike Lee! 

The Verco medal, established by the Royal Society of South Australia is awarded for distinguished scientific work published by a Fellow. It is the highest honour that the Society can bestow. Only those who have made a significant, outstanding contribution to their field of study receive the award. Previous winners include the esteemed Prof Walter Howchin in 1929 (first medal awarded), HG Andrewartha, JB Cleland, and fellow earth scientists & palaeos Reg Sprigg, Michael Archer and Sir Douglas Mawson.

Mike Lee’s area of expertise earning him the Verco medal, covers just about every taxonomic group within palaeontology you can imagine. Mike has helped construct the family trees Cambrian arthropods from Emu Bay (Kangaroo Island), dinosaurs from the US, giant flightless birds from New Zealand, and snakes and lizards of Australia. Despite having worked on such a broad range of animals, Mike has a soft spot for reptiles, having completed his PhD on early turtle body plan evolution (published in Science) and afterwards travelled the world building a large collection of morphological characters for lizards and snakes to unravel their origins (just check out his Google Scholar page). He now acts as primary supervisor for the palaeontology students in our lab who want to work on fossil reptiles, or who are interested in how morphology and molecular evidence can be used to construct family trees. Mike’s true love is Bayesian methods, integrating probability into statistical analyses, which he believes is integral to the future of science.

For those of you who haven’t met Mike yet, he presented our Palaeo in the Pub: Dinosaurs with Wings this year, as well as a Sprigg Lecture at the South Australian Museum on a similar topic. Mike spends most of his days at the Museum but if you are interested in fossil reptiles or want to congratulate him on his award he will be at Flinders on Saturday evening for the Inaugural Wells Palaeontology Lecture & FUPS reception Celebrating 30 years of Palaeontology at Flinders.

By Research Associate Dr. Alessandro Palci

It’s quite odd how sometimes things unexpectedly come back from our past in circuitous ways. It was the summer of 2000 when, still an undergraduate student, I was touring the Dolomites as part of a field trip organised by the department of Geological Sciences of the University of Trieste (Italy).

It was a sunny spring day, and I was looking down at some Jurassic dinosaur footprints, when I first heard of a small fossil reptile that had recently been found nearby, in 240 million-years-old rocks. The rumour was that someone was already working on its description. I won’t deny that I wished I could be that someone. Unfortunately, I was only an undergraduate student at the time, and a long way to go before my first palaeontological paper would be published.

The fossil was described and published by Silvio Renesto and Renato Posenato in 2003. It turned out that the fossil was preserved in rocks that originated on the bottom of a warm shallow sea. The little reptile was one of very few terrestrial organisms that had been entombed in those marine sediments, which makes its discovery incredibly fortuitous.

Renesto and Posenato named the fossil after its relatively large hands: “mega” and cheiros” are ancient Greek words for “large” and “hand”, respectively. They then classified the reptile as a member of the Lepidosauromorpha, a broad group of reptiles that includes lizards, snakes, tuataras, and many other more distantly related reptiles. Ten years later, in 2013, Megachirella was re-described by Silvio Renesto and Massimo Bernardi, and the authors confirmed the classification of Megachirella as some kind of lepidosauromorph based on a phylogenetic analysis, but did not resolve its affinities very precisely.

Another four years went by, and in the summer of 2017 I flew to Calgary, to attend the 77th annual meeting of the Society of Vertebrate Paleontology. International meetings are a great opportunity for networking, but also for catching up with old friends spread around the world. One of these friends of mine is Tiago Simões, who was finishing his PhD in Systematics and Evolution at the University of Alberta. He told me that he was working on an interesting fossil reptile, what he suspected could be the oldest fossil lizard. He also told me that he was looking for someone who could work on its CT scan data. At the time I had no idea what the mysterious fossil was, but I had considerable experience working on CT scan data, so I offered to help him out.

It turned out that the fossil of Megachirella had been scanned at the ICTP Elettra synchrotron facility in Trieste, Italy, and that was the data that Tiago wanted me to work on. Only now I realize how crazy all this is, it was that very same little fossil reptile I heard about in the Dolomites seventeen years before, and it had somehow finally found its way into my hands. The CT scan data provided a wealth of new information about the little fossil, and this helped us place Megachirella in quite a different and much more interesting light.

The three-dimensional digital images generated from the CT scan data allowed us to look through the rock, at parts of the skeleton that were inaccessible before, without incurring in the risk of damaging this unique fossil by removing the embedding rock mechanically. What we discovered was that Megachirella already shows modifications in its skull and limbs that are shared with modern lizards (like for example a triradiate squamosal at the back of the  skull, a mobile quadrate bone bearing the upper jaw joint, an ulnar patella in the elbow, and the loss of the first distal carpal in the wrist), but it also retains some extra bones that were commonplace in early reptiles, and were lost much later in lizard evolution (like gastralia along the belly, and a quaratojugal in the cheek region). We included this new information in a an extensive phylogenetic dataset that Tiago had put together during the course of his PhD, and it turned out that Megachirella is indeed a stem-lizard. The oldest and most primitive lizard known to date, a finding that earned us the cover of the latest issue of Nature.

Megachirella gives us a new window on what the first lizard probably looked like and helps us understand how the anatomy of earlier reptiles gradually changed over time, in little steps, to produce the body shape of lizards that is familiar to us today.

This fossil is important not only because its anatomy bridges a gap between two major groups of reptiles, much like Archeopteryx, but also because it extends the fossil record of lizards back in time by about 70 million years, into the middle Triassic (~240 million years ago). That lizards must have been present in such deep time had been predicted by some molecular studies of modern lizards, based on the speed at which DNA strands accrue mutations over time; however, the oldest known fossil lizards before Megachirella were frustratingly “young”, coming from rocks that originated in the Jurassic, only about 167 million years ago.

Megachirella tells us that lizards were indeed around in the Triassic, and based on a new estimate of the rate of evolution of lizards, we can now place the origin of these reptiles in the late Permian.

So, next time you are out in the field looking for fossils and see a lizard scampering around, think of Megachirella, and that the evolutionary history of this amazing group of reptiles started 260 million years ago, long before the first dinosaurs appeared!

Dr Alice M. Clement

The appearance of the first tetrapods, the limbed vertebrates which today dominate the land, represents one of the greatest ‘steps’ in evolution. Evidence for the first vertebrates with four limbs and digits (fingers and toes) can come from fossilised body parts, or from trace fossils, such as footprints.

The oldest widely accepted tetrapod trackway, and indeed the oldest widely accepted evidence for tetrapods in general, come from intertidal sediments from a quarry near Zachełmie, Poland. These prints, first announced in 2010, have been dated to the Middle Devonian, about 395 million years ago, and more than 18 million years older than the oldest tetrapod body fossils.

The trackways indicate they were made by flat-bodied, lizard-like creatures, some of which must have reached up to 2.5m in length. There are multiple trackways from several individuals, and most importantly, they clearly show the impressions of digits!

In Australia there have been some similarly impressive finds of trackways in Devonian rocks, including those from Glenisla and Genoa River in Victoria. The Genoa River tracks from far-eastern Victoria, are Late Devonian in age and were the first tetrapod trackways ever described from the “Age of Fishes” when first described in 1972. There is evidence of two different types of animals, clearly showing overlapping and alternating impressions of the fore and hind limbs clearly showing digits.

The Glenisla trackways are more problematic. The trackways were described in 1986, identified on a slab of rock in a homestead courtyard near the Grampians. However there remain persistent doubts over the precise age of the rock, with estimates ranging as far back as the Silurian Period, and the identity of the track maker has been questioned. If these really are tetrapod tracks and the Silurian date is correct, this represents the oldest evidence of limbed vertebrates in the world!

Professor John Long from Flinders University wanted to settle the controversy once and for all and so assembled a team of tetrapod trackway hunters to boldly venture into the remote wilderness of Victoria in search of fresh evidence. His team consisted of the walking encyclopaedia Dr Brian Choo, whizz-kid PhD student Ben King, venerable Swedish Professor Per Ahlberg, and myself.

Our first stop was the Grampians, where we were joined with an old friend of John’s, Peter Ward, a structural geologist and all-round handy camp guy. In addition to examining the original track-slab at Glenisla homestead, we visited two disused quarries and were able to pinpoint the true provenance of these enigmatic prints, along with the discovery of numerous other trace fossils made by various invertebrates. Of course, being in the Grampians, we were also rewarded with some spectacular views, incredible wildflowers and many friendly kookaburras and shingle-back lizards around our campsite.

After a few days we moved onto Melbourne for a much-need shower and for the chance to examine some old fossil samples collected decades ago from Genoa River, currently housed at The University of Melbourne Geology Department. The specimens contained tantalising material from a number of different types of fish and gave us great hope of finding new specimens in the field.

The Genoa River site is located in spectacular country within the Coopracambra National Park in far-eastern Victoria, some 50km northwest from Mallacoota Inlet. The National Park is a true wilderness and the playground of only the most determined hikers. For us it was either a 25km+ trek up and down cliffs through thick, temperate rainforest with all our gear and supplies, or a slightly more exhilarating transport option: GET TO THE CHOPPER!

Our weather-beaten but highly experienced pilot, Grant Shorland and his wife Ros, helped us reduce our load to just the essentials, and squeeze (just barely) into the 6-seater Écureuil. By following the course of the Genoa River, we were able to identify the area where we hoped to find fossils. However, the forest was so thick and the river often channelled between tall cliff faces, we struggled to find a suitable sandbank on which to be put down.

Even though we had seen the park from the air, it was still a surprise to experience how difficult it was to move through the undergrowth. We soon resorted to rock-hopping and eventually simply wading through the river itself. Genoa River was a spectacular site in which to spend four nights – we were lucky to share our camping spot with a plethora of skinks (Brian can tell you which species), beautifully-coloured water dragons, a few snakes, an easy-going platypus (that let us share his pristine swimming hole), and a deafening chorus of giant cicadas. 

While new tetrapod-trackways remained elusive, we did manage to map the geology of the area, find some fish fossils and even an arthropod trackway suggesting we were on the right track! All of the team were in agreement that any future trips should take inflatable pack-rafts for ease of traversing the beautiful yet wild country of far-East Gippsland!

Alice didn’t come to Flinders Palaeontology via the usual route – she travelled half the world to get here, but, as in all the other profiles we have presented here, she just followed her dreams….

Somewhat unusually for a palaeontologist, I never caught the “dinosaur bug” as a child. I always had a great love for animals and the outdoors, but wasn’t one of those children who knew all the dinosaur names. I was born in England, but my family moved to Australia when I was four years old. My parents were amazed by their new country, and we endeavoured to experience as much of it as we could.

Every school holiday was spent camping in the bush around south-eastern Australia, feeding King Parrots from our hands, diving for abalone off the Victorian coastline, chasing small skinks and being chased back by giant goannas.        I held a special fascination for marine animals, taking a set of Great White Shark jaws to Ascot Vale Primary School for “show and tell”, much to the bemusement of my classmates, and later opting to visit the Tasmanian Aquaculture and Fisheries Institute for my year 10 work experience.

It was in year 10 that my feelings for science really began to blossom. A particularly enthusiastic and inspiring teacher, Mr MacDonell, opened up my eyes to the fascinating world of science, something that I had only found daunting before then. I then went on to study Biology, Chemistry and Maths Methods, alongside English, Renaissance History and Japanese in my final years of high school (VCE).  I took a year off after high school to go on a two-month camping trip with my father to the Gulf of Carpenteria and Arnhem Land, before moving to Hokkaido, Japan, to teach English for six months.

Upon my return to Australia I enrolled in a double Arts/Sciences bachelor degree at the University of Melbourne so that I could continue my Japanese language studies. Finding the Japanese courses a bitter disappointment, I focussed instead on my Science, going on to do a double major in Zoology and Conservation. It was then that I came to another point in my life that changed my trajectory forever.

Although having not studied any palaeontology at university, I knew I had an interest in evolutionary biology, but wasn’t tempted by any one of the four major themes of research being offered by the Department of Zoology. I spoke to Dr David Young, whose comparative anatomy lectures I had enjoyed most of all, and asked his advice about what to do. David suggested I speak to a palaeontologist he knew who was working at the Melbourne Museum, Prof. John Long.

Right: Alice in the field at the Gogo Formation, WA in 2008

Fortuitously, John was shortly due to give a public lecture at RMIT about his research. I was immediately blown away by the spectacular Gogo fossils he showed. I commenced my Honours project with him shortly thereafter for my first foray into palaeontology. John had a near-complete lungfish fossil from Gogo that had been discovered the year prior, and entrusted me to prepare and describe the specimen. In my Honours project I named my first lungfish, Xeradipterus hatcheri, named for Lindsay Hatcher who had discovered the specimen.

In 2009 I commenced my PhD, again working with John at the Melbourne Museum, but this time enrolled at Australian National University (ANU), Canberra, under the additional guidance of Prof. Tim Senden. I continued my work on fossil lungfish from Australia, going on to describe another two new species and with the opportunity to partake in some incredible fieldwork adventures.

Halfway through my PhD, John threw a spanner in the works and announced he was to move to Los Angeles. This meant that I no longer was to be working alongside one of my supervisors, and ANU started to make more and more grumblings that I should really be working on campus in Canberra. In late 2010 I moved to Canberra, leaving my partner, friends and family behind. In the next 18 months I worked closely with Dr Gavin Young who agreed to come on as an additional supervisor for me. I was also fortunate enough to meet the powerhouse duo of Prof Ken Campbell and Dr Dick Barwick, two giants of Australian palaeontology, and known in particular for their huge body of work on fossil lungfishes. During my PhD I had wonderful opportunities for travel, visiting fossil collections in museums around the world, and meeting scientists whose names I had only read in papers before then. I visited and worked in the Natural History Museums of London, Paris, Stockholm, Edinburgh, LA, Chicago, Washington DC, Philadelphia and New York. There is something truly magical about being granted access to the countless cabinets of priceless treasures held in the world’s best museums.

On my travels I had met Prof. Per Ahlberg and colleagues at the International Congress on Palaeontology in London 2010, and visited his Evolution and Development lab in Uppsala, Sweden. I immediately fell in love with Sweden and the friendly atmosphere of his working group. After graduating with my PhD in 2012, I hassled Per until he gave me a job. This is my top tip for up-and-coming palaeontologists; there is a lot to be said for persistence! In early 2013 I moved to Sweden and worked with Per and his group for just over two years. There I was very productive scientifically and also made many good friends, including meeting the man who would eventually become my husband, Niels Nielsen.

Above: Alice and Niels visiting Innes National Park, South Australia in 2017

Niels and I moved from Sweden to Australia in late 2015, and I took up my current role, again working with John Long, at Flinders University in Adelaide. Having grown up in Melbourne, Adelaide was a new city for the two of us, and we took great pleasure in exploring the beaches, wineries and burgeoning café culture that our new home had to offer. Now I was working in the largest Vertebrate Palaeontology group in Australia, alongside experts in Mammals (Gavin Prideaux, Rod Wells, Aaron Camens), Birds (Trevor Worthy), Reptiles (Mike Lee) and of course fish! Here I continue my work on fish, using modern scanning and imaging techniques to examine spectacular 3D fossils to answer questions not answerable by more traditional means. 

I am so incredibly fortunate to have a job doing what I absolutely love, constantly learning and discovering things never before known to the human race! Aside from palaeontology, I enjoy being active and have played water polo (badly) for more than half of my life. I still enjoy the camping and the outdoors, travel, as well as sharing good food and wine with friends.

Professor Long is an expert in ancient fishes, and has undertaken many international expeditions in search of them, but he has many other strings to his bow, some of which are quite surprising… read on.

My interest in palaeontology started  in grade 2 at school (aged 7) when I sat next to a kid whose father collected fossils for a hobby. I was invited to go ‘fossiling’ with them to a quarry near Lillydale, Victoria, where we found 400 million year old Devonian trilobites and other marine creatures. From there I discovered sites closer to home, around Melbourne, so searched the beach at Beaumaris for sharks’ teeth and other treasures, plus with parental help enjoyed occasional trips to Tertiary sites further afield like Geelong, Torquay, or Hamilton. My collection grew and I began researching my fossils and keeping notebooks full of drawings about them . I was always keen to visit other fossil sites of different ages, and Victoria was perfect as it had almost the entire geological sequence within a few hours of Melbourne..

At age 12 my cousin and I jointly won an intermediate division prize ($50) in the State of Victoria Science Talent Search for work summarising Victorian fossils, and at age 14 I won the junior division 1st prize ($60) for my descriptions of “ Fossil Fishes of Victoria” (200pp).These notebooks included attempted scientific descriptions of undescribed species of Miocene fishes from Beaumaris amongst other things. My teenage years were a mixture of fossil hunting on weekends, karate lessons, and as I turned 17, getting my first motorcycle so I could get around on my own.

Above: John aged 19 on his BMW motorcycle.

By final year at school I was convinced I wanted to become a palaeontolologist, so I did the compulsory maths, physics and chemistry subjects and successfully won a place at Melbourne University to undertake a science degree. After two years there I did all the zoology, botany and geology units I was allowed to do (including 4 third year palaeontology units), then transferred across to Monash University, because Prof Pat Vickers Rich had just started there, and Melbourne lacked any vertebrate palaeontologists. Prof Jim Warren, also a vertebrate palaeontologist, was the Head of Zoology at the time, and had just discovered a rich site full of new kinds of Devonian fishes at Mt Howitt. I enrolled in third year, and that year completed a research project on Bacchus Marsh Diprotodon taphonomy. My Honours year (1980) was on Bothriolepis fishes from Mt Howitt, and this lead me to an MSc (which I later converted to a PhD) on Victorian Palaeozoic fish fossils.

I’ve sometimes been asked why I stayed at Monash to do my PhD. I did get an offer to go to Berkeley in the USA and work on what I regarded as ‘second rate fossil material’, but stayed at Monash where the entire Mt Howitt fauna was mine to describe – all new genera and higher level taxa of fishes. I’ve never looked back from there. It’s not where you do your thesis that counts, but whom you work with and the quality of fossil material that you work on that will make your name and set you off on a career in palaeontology.

During some of my university years I lived up at Emerald, near Tom and Pat Rich, sharing a house with my cousin, Tim Flannery. We would often do work for the Rich’s, picking out fossil mammal teeth from sieved residues, and we accompanied them on several field trips, getting first hand experience at excavating Diprotodons (at Bacchus Marsh) or searching for Pliocene mammals at Hamilton. I also spent a week working with Janette Hope and Ken Aplin at McEacherns cave near Nelson sieving cave sediments for fossil bones. Most of my time at University I rode motorcycles to get around. I had an old BMW R60, a Honda 750/4 and some smaller bikes.

After completing my PhD in late 1983 in just under 3 years, my family moved to Canberra where I had a 2 year postdoctoral position working with Devonian fish experts Gavin Young, Ken Campbell and Dick Barwick. This allowed me to collect at Taemas and run an expedition to central Queensland, where we collected Carboniferous fish material. From there we moved over to Perth for 2 years while I held a Queen Elizabeth II Award at the University of WA, and this allowed me to go to Gogo for the first time in 1986. I applied for a National Geographic Grant and was successful, so bought my own second hand 4WD, and funded a 5 week trip to the Kimberley. We found many spectacular specimens, including new genera of placoderms and lungfishes, and the first complete head of Gogonasus. However, it was an expedition plagued with vehicle breakdowns, which on two occasions, saw me undertake very long walks to the highway at night to get help.  When this ran out, I was offered a 2 year position at University of Tasmania, working with Dr Clive Burrett on the Palaeozoic fossils of SE Asia.

This involved several field trips working in the Devonian of Thailand and Vietnam, where we found many fish fossils. I also wrote some papers on conodonts at this time. Sometimes our field work was a bit risky, like working in the jungles of the Golden Triangle near the Burmese Border. At one time we were questioned by local ruffians with large guns, and escaped an incident by being picked up just in time by our Thai driver.

All through these six years as a postdoc I routinely applied for jobs at universities, but missed out on these positions. At the end of 1989 I applied for a job at the Western Australian Museum (WAM) as Curator of Vertebrate Palaeontology, and got it. I settled in to that role for the next 16 years, searching many remote parts of Western Australia for fossils.
When I started my job at the WAM I had no computer, nor any funding for field work. I decided to be a ‘scientific entrepreneur’, so started The Dinosaur Club in 1990, and within a year had 10,000 members paying us $10 each, so although most of these funds went to the museum, my share enabled me to buy a new computer and run some field expeditions. I ran the club for the next 16 years publishing almost 20 issues of ‘Dinonews’ magazine with help from my colleagues at the WAM.  Highlights of my time at the WAM include the many trips to Gogo and the Pilbara Devonian sites, as well as leading 3 expeditions to the Nullarbor Cave sites (2002-2004), working with Gavin Prideaux at Flinders and the caving associations who discovered the sites. My three-month long expedition to Antarctica in 1991/92 collecting Devonian fishes was another highlight, resulting in many new species described, and my book about the trip called ‘Mountains of Madness- A Scientist’s Journey Through Antarctica’ (2000). Working the Mesozoic reptiles was another plus, as we found the first articulated Mesozoic marine reptiles in WA near Kalbarri. I also described WA’s first dinosaur remains, naming the Jurassic theropod ‘Ozraptor’ 1998.

Aside from doing scientific research and writing my first books (Australian Dinosaurs, Rise of Fishes, Prehistoric Mammals of Australia etc.), my time in WA was also spent returning to my childhood sport of karate and my hobby of riding motorcycles. In 1992 I began martial arts training again, achieving my black belt in 1996. That same year I rode my BMW K100RS bike across Australia and back. I reached 3rd dan black belt in karate in mid 1999, and that same year competed in an international tournament in Okinawa (1999) where I came home with gold medal for performing a team event with sai swords. I eventually became the state Chief Instructor of my style, Uechi Ryu, for 14 years, mentoring nine of my students through to black belt grades, and taught Matayoshi Kobudo (weaponry) as well. It was a very active time in my life, but the hard physical training definitely helped on the long field trips.

Above: Gjaj-martial arts Training with Okinawan master Gaja in Perth 2002.

At the end of 2004, encouraged by Tom Rich, I was appointed as Head of Sciences at  Museum Victoria, and moved to Melbourne. Although the job included a high degree of administration, I was allowed to keep researching and managed to have a productive time in this job. I supervised three PhD students (Tim Holland, Brian Choo and Alice Clement), and was able to run expeditions to Gogo and central Queensland, and attend major overseas meetings. During this time (2004-2009) we published five Nature papers (three about about the origins of sex based on our embryo finds in Gogo fishes), plus many solid descriptive works, and several books. These included children’s books like The Big Picture Book series (illustrated by Brian Choo), one about the history and significance of the Gogo sites (Swimming in Stone), a new edition of The Evolution Revolution, and a book featuring artwork by Peter Schouten, Feathered Dinosaurs –The Origin of Birds.

In early 2009 my wife Heather and I decided to look for a job overseas as we had never had the experience of living in another country. I was accepted for the job as Vice President at the LA Country Museum and moved to Los Angeles in late 2009. My three years in LA were very busy, as we were building two new galleries of palaeontology and one of local history. Nonetheless I enjoyed my time there and I was allowed to periodically visit Australia for field work and research collaboration, so I kept my research ticking over.

Finally, in late 2012, I was offered a permanent on-going role at Flinders University as one of their new Strategic Professors, and was very happy to return to Australia in a job that was research focused.

My advice to up and coming young palaeontologists is to take any opportunity you can get to participate in field work, and work far and wide as possible to gain experience working with professional palaeontologists. Lead a balanced life, keep healthy and active, and foster other interests aside from science, as I have done with my karate and motorcycles. I think this approach really helps keep the brain developing new pathways, and thus better adapted to problem solving.
