Prof. Richard Cloutier

Bonjour! Canada’s foremost fossil fish fanatic, Prof. Richard Cloutier, from the Université du Québec à Rimouski (Canada), is currently on sabbatical here at Flinders University!

Richard was born in Canada but obtained his PhD from the University of Kansas (USA), before moving onto several postdoc positions throughout England and France, and then later returning to Canada.

I’m a real fan of his research and he’s got a huge body of work investigating the palaeoecology, palaeoenvironment and systematics of Devonian fossil fishes, especially those from the famous Escuminac Formation “Miguasha” in eastern Canada (such as the famous Eusthenopteron). I would really, really love to go there someday.

Richard is here in Australia to work with John Long and I on a number of projects together, the most exciting of which is the description and investigation of a beautiful specimen of the tetrapodomorph fish, Elpistostege (move over Tiktaalik, there’s a new ‘fish-apod’ in town!)

This month, Richard treated the Ecology and Evolution group here at Flinders University to a fantastic talk about his research. You can learn more or watch it here.



International Day of Women and Girls in Science

Yesterday was the International Day of Women and Girls in Science. Even though we have come leaps and bounds in recent years, we still have a long way to go to ensure women and girls are not excluded from participating fully in science. According to the UN, less than 30% of researchers worldwide are women. Gender biases and stereotypes must be combated to enable more young girls and women to participate in science-related fields.

It was for this reason that I was particularly glad to be talking to Work180 yesterday about running a palaeontology activity in their upcoming Super Daughter Day this March in Melbourne. On the day I’ll be exploring STEM (Science, Technology, Engineering and Maths) with girls aged 5-12 and encouraging participation in the huge variety that STEM has to offer.

It’s been so heartening during the last few years to see more visible positive role models for girls in STEM, and even some great new toys such as Lottie the fossil hunter endorsed by  Trowelblazers. (My niece is the lucky recipient of many of these gifts!) Lottie has an age-appropriate body shape and comes with her own field tools and backpack.


If you want to learn more about some amazing people in STEM, check out Australia’s Science Channel “Women in STEM” page for videos and articles about women doing cool things in fields ranging in everything from space archaeology to robotics. (And if you look closely, you might see a familiar face in the article “How to become a palaeontologist.”

Scope TV

Happy New Year and welcome to 2019!

I hope the heads are not too sore this morning and that you are all ready for another year full of wonderful lungfish-y and palaeo fish news from yours truly. My blog has been online for one year now and I’ve really enjoyed sharing snippets of my work and passion for evolutionary biology. Thanks to all for the positive feedback so far.

If you’re still feeling a little shabby this morning and not ready to race out into the new year just yet, then why not settle down with a cup of tea for an episode of Scope TV? Scope is a “fast, funny and informative children’s science show produced in association with the CSIRO…. created to demystify the world of science and technology, and make it relevant, accessible and above all fascinating to a young audience”.

My research on the stem-osteichthyan (early bony fish) Ligulalepis, was featured in Season 4, Episode 78 (I’m on between 17:56-20:47). You can watch the full episode here: , or if you are watching from outside Australia or want to skip straight to my segment click HERE

I hope you enjoy it (no, not that fish!)

PalAss, Bristol

The final leg of my Europe trip took me to Bristol, in Somerset, England. The Annual Meeting for the Palaeontological Association was held in and around the University of Bristol and the city Museum over four days this December.

The conference kicked off with a special symposium “Frontiers and Advances in Dinosaur Palaeobiology” on Friday in the impressive Great Hall in the Wills Memorial building, followed by regular sessions over the weekend. The social programme was almost as busy as the scientific one, with many opportunities to socialise and network with fellow palaeontologists.


I presented a poster on the “Digital palaeoneurology of the ‘chirodipterid’ lungfishes from the Devonian” – outlining one of my current projects on the fossil brains of an iconic group of fossil lungfish. It was my first experience presenting a poster rather than an oral presentation, and as such, I found the whole experience much more relaxing than usual!

Monday took us to the Somerset coast on a cold but clear day to inspect the Triassic-Jurassic section on the beach at Watchet. We searched for beautiful nacre “mother-of-pearl” ammonites and ichthyosaur bits, then enjoyed traditional fish and chips at the local pub and a pint (or two) of delicious cider. Many thanks to Dr Jakob Vinther (bottom left image) and colleagues for a very well organised, highly informative and fun meeting and field-trip.


ESRF, Grenoble

What would you like to do on your 30th birthday? Shut down for two years and replace your major organs? It may not sound like an ideal celebration, but that is what the European Synchrotron Radiation Facility (ESRF) will do this December.

The world’s first third-generation synchrotron light source (ESRF) was built in 1988, and will pause the world’s “most intense X-rays for research” to enable the construction of a new storage ring and the addition of even more beam lines. The Extremely Brilliant Source (EBS) is not scheduled to come back online until late 2020.

I feel especially lucky to have been here in beautiful Grenoble this week working with colleagues from Uppsala University, Sophie Sanchez and Per Ahlberg, on the very final experiment on beamline ID 19 before the scheduled shutdown. ESRF is the only synchrotron in the world with a beam powerful enough to perform this experiment at the super high resolution required (down to 0.7μm voxel size!).

IMG_4637Per and Sophie inspecting a mounted specimen on the ID19 beamline at ESRF

During 72 hours of beam time, we work 24/7 with help from ESRF researcher, Paul Tafforeau, to scan as many specimens as possible. Sophie’s project is looking at the bone histology of the fins and limbs over a number of significant evolutionary transitions: the fin-limb, water-land, and the characteristics that appear in the first amniotes (animals that lay a waterproof egg, e.g. the first reptiles).

Bone histology, microanatomy and skeletochonology can be remarkably informative about the lifestyle and life history traits of an animal. For example, the bone microstructure can indicate whether an animal matured quickly, or had a long juvenile phase – as shown recently by Sophie and colleagues in Sanchez et al. (2016) and other works.

Skeletochronology works on the same concept as counting tree rings in trees, and can map various changes in life history, development and physiology inside the bones of an animal. And very significantly for these experiments, the structure of the bone can indicate whether the bone was capable of sustaining an animal’s weight on land, or if it must have remained buoyant in the water.

It’s been an exhausting yet exciting few days scanning many stunning specimens sourced from all over the world. I look forward to continuing our work on these projects in the coming years (and catching up on some sleep!)

Berlin Museum für Naturkunde

I’ve had a wonderful few days working at the Berlin Natural History Museum. I was interested to see the original specimen of a lungfish (Chirodipterus wildungensis) that was the first to have the internal space for the brain described. This was achieved over 65 years ago using the “shatter method” (which is destructive as it sounds!)


I am also interested in a small coelacanth skull, called Euporosteus eifeliensis, from the Devonian of Germany (~383-388 million years ago). It is preserved in 3D and is only known from a single specimen!

To study both the fossil lungfish and coelacanth, I used the traditional method of making observations using a microscope, but also will 3D model them both using the museum in-house CT scanner and segmenting software back in Adelaide.


I’m so very grateful to Dr. Florian Witzmann, curator of fossil fish and amphibians, and Dr. Kristin Mahlow, who works in the CT lab, for their assistance this week. I’m looking forward to continuing our collaboration together.

Another perk of working in the museum was the opportunity to browse through their galleries, which include a beautiful Archaeopteryx specimen on display, as well as a visiting T-rex skeleton called Tristan. As one of the best preserved and most complete T-rex skeletons in the world, he was very impressive!


New “stem-tetrapod” paper out today!

I’ve just surfaced in Berlin and my jet lag-addled mind is pleased to see my latest paper, co-authored with my Flinders University colleagues, John Long and Brian Choo, published today in the Earth and Environmental Science Transactions of The Royal Society of Edinburgh (now that’s a mouthful!).

The paper is entitled “New Insights into the origins and radiation of the mid-Palaeozoic Gondwanan stem tetrapods.” In it, we provide new detail about Koharalepis, a fish from the Middle Devonian Aztec Siltstone of Antarctica, using 3D synchrotron data. We also propose some alternate biogeographical and phylogenetic models of stem tetrapod origins and radiations with a distinctly Gondwanan perspective (remembering that Gondwana was the great southern supercontinent that Australia and Antarctica were once a part of).

The paper forms part of a special volume written in honour of Prof. Jenny Clack, who has been seminal in studies of the “fish-tetrapod” transition, and who wrote the absolutely wonderful Gaining Ground: the Origin and Early Evolution of Tetrapods. It has been an absolute honour to get to meet Jenny at various conferences over the last decade, and her impact to the field of early vertebrate evolution shall never be forgotten.


Planetarium “Supernovas”

I was honoured to be asked to speak to the Adelaide Planetarium “Supernovas” this week. The “Supernovas” are astronomy students who meet at the planetarium to keep their knowledge of celestial objects up-to-date, with lectures by invited speakers from other disciplines each month.

My talk was entitled “Fish, Fossils and Brains” and I got to speak about my favourite avenue of research, palaeoneurology. Palaeoneurology is the science of fossil brains and neurobiological evolution. The discipline was founded by Tilly Edinger in the 1920s when she described the natural endocast (mould of the internal cavity of the skull) of the Mesozoic marine reptile, Nothosaurus. Prior to Tilly’s work, scientists only compared the brains of living animals without any input from the geological record.

I’m most interested in the changes that occurred across the fish-tetrapod transition. The “lobe-fins” (Sarcopterygians) comprise nearly half of all vertebrate species, and unravelling the major innovations that occurred in the brains of the first tetrapods (the earliest terrestrial vertebrates) is pivotal for understanding our very own neural evolution.

It was especially cool to be treated to a show inside the planetarium after my talk. Many thanks to Paul Curnow (in the photo below) for the invitation and to the “Supernovas” for their interesting and thought-provoking questions. 46508856_367621303981484_9000653724581888_n

Congratulations, Phoebe!

A big “CONGRATULATIONS” to my Honours student, Phoebe McInerney, who today had her final seminar and viva. Honours in the sciences is a rigorous year-long (only 9 months, really) independent research project which usually results in the production of a thesis.

Phoebe’s thesis was entitled “Analysis of Syrinx, Hyoid, and Larynx Morphology in the Southern Cassowary, Casuarius casuarius, (Aves, Palaeognathae) and Implications for Palaeognath Phylogeny.”

Her project was a pretty epic combination of traditional anatomical description, modern scanning methods (diceCT and 3D segmentation) and cladistic analyses, all in the pursuit of resolving Palaeognath evolutionary relationships.

Palaeognaths represent just ~1% of all living birds and includes the large, flightless forms such as ostriches, emus, rheas and the kiwi, and the flighted tinamous. This group also includes extinct forms such as the moa and elephant bird.

The large and flightless birds all share features related to their lifestyle such as reduced wings and strong legs that have likely arisen as a result of “convergent evolution” (called a homoplasy) which can make reconstruction of the evolutionary family tree very difficult.

Instead, Phoebe looked at the syrinx, hyoid and larynx (the vocal organ and its connected parts) in these birds to find characters that would reflect the true evolutionary history of the group.

I co-supervised Phoebe along with the Bird Man himself, Trevor Worthy, and phylogenetic analysis guru, Mike Lee. I’m very happy to have been involved and have great hope for Phoebe’s future academic career. CONGRATS PHOEBE, AWESOME JOB!
