Gogo grant funded!

Father Christmas came early this year! Our Discovery Grant “The Devonian Gogo Fauna: Diversity, Palaeoecology and Global Significance” from the Australian Research Council (ARC) was funded! This grant gives us three years of funding for research and to support students and other staff associated with the project.

John Long (Flinders Uni), Kate Trinajstic (Curtin Uni) and I are Chief Investigators, and we’ll be collaborating with a fantastically diverse range of international partner investigators including Carole Burrow (Queensland Museum), Per Ahlberg (Uppsala University), Derek Briggs (Yale University), Zerina Johanson (Natural History Museum London), Christian Klug (University of Zurich) and Richard Cloutier (University of Quebec).

The Late Devonian Gogo Fm. in Western Australia (380 myo) is one of the richest and best-preserved assemblages of fossil fishes & invertebrates on Earth. We will reconstruct the trophic relationships of the reef and test the resilience of the ancient reef ecosystem.

Additionally, we will work with local indigenous stakeholders to assess the heritage significance of the site. We aim to develop a long-term management plan to protect and conserve this amazing site and help to grow geotourism in the region.

I believe that Gogo is the best fossil fish site in the world and I can’t wait to get back there in the coming years with our collaborators, and see what we can achieve with this crack team of researchers we’ve assembled. Merry Christmas to us, indeed!

New paper on tetrapod-like fish from Queensland

Hello! I’m taking a brief break from my maternity leave to tell you about my latest paper, published last week in the Journal, PeerJ; A fresh look at Cladarosymblema narrienense, a tetrapodomorph fish (Sarcopterygii: Megalichthyidae) from the Carboniferous of Australia, illuminated via X-ray tomography.

Four panels: a photo of the specimen, a radiograph of the specimen, a tomogram (slice) of the specimen, and a 3D model of the specimen. Image credit: Alice Clement.

In my paper we use microCT and synchrotron technology to image some spectacular 3D fossils of a fish known as Cladarosymblema from about 330 million years ago in what is today known as Queensland, Australia.

Cladarosyblema was a type of tetrapod-like fish known as a ‘megalichthyid‘. These fish grew to large sizes, lived in freshwater environments, and would have been fearsome predators. They were one of the few tetrapodomorph groups that survived the end Devonian extinctions, and persisted up until the Permian Period (299-252 mya). Cladarosymblema is the only megalichthyid known from Australia, and one of just two known from the ancient southern supercontinent, Gondwana.

Cladarosymblema was originally described in 1995 from several specimens, but using scanning technology we were able to uncover much of its internal anatomy that had until now remained hidden. In particular we could describe the gill arch skeleton, parts of the shoulder girdle, vertebrae and upper roof of the mouth bones (palate).

Additionally, we were also able to isolate the cranial endocast from Cladarosymblema, which gives insights into the size and shape of the brain of this animal. The area for the pituitary gland (so-called the master gland) is relatively large, suggesting a significant role in regulating various important endocrine glands. The overall shape of the endocast is more similar to that of early terrestrial vertebrates (tetrapods) than to most of the fish left living in the water. Was it some of these adaptations that enabled Cladarosymblema’s relatives to colonise land?

Furthermore, the membership of the ‘megalichthyids’ has been controversial, with several recent studies finding conflicting results. We ran a phylogenetic analysis (analysis of relationships) and found that the megalichthyids form a natural clade (are monophyletic).

I want to thank the Queensland Museum for allowing us access to the beautiful specimens, as well as all of my co-authors, reviewers, and the editor who handled the paper at PeerJ. All of the scan data and 3D models are available at MorphoSource, and the phylogenetic matrix can be accessed on MorphoBank.

A different kind of project

I’ll be stepping back from my monthly updates a bit as I prepare to go on maternity leave next week. It’s exciting, terrifying & overwhelming, and I understand it will change the life of me and my partner forever. Bubba is due in just over two weeks!

This is what a scientist looks like (8 months pregnant).

I’m all too painfully aware of what the statistics say and how the penalty of motherhood continues to impact women disproportionately compared to their male counterparts (fathers get promoted, while women are pushed out via the #leakypipeline).

Even today, it was confronting to look around and struggle to find role models who had become mothers and managed to succeed to senior levels in STEM #WomeninSTEM (although I’m inspired by the few exceptions I do see).

I did also manage to be #PregnantInTheField relatively early on. Very doable (with a few extra toilet breaks and early nights to bed, and some extra loose pants!) I did miss being able to enjoy a glass or two of red by the campfire at the end of the day, however.

I am really hopeful that things continue to improve and that my career isn’t too negatively impacted by choosing to have children. Sometimes I can’t help but wonder what is the point of all the initiatives to encourage girls into STEM if we don’t retain women in STEM?

AsiaEvo Conference

The last 18 months have transformed many, many things, including the world of scientific conferences. The pivot to online virtual events means great things for accessibility and inclusion (although I do miss many things about the old-style in-person events too).

This week I gave a talk at the 2nd AsiaEvo Conference, which was organised as a joint meeting with the 23rd Annual Meeting of Society of Evolutionary Studies from Japan. I was one of the invited speakers for a symposium “The rise of fishes: the origin and early evolution of non-tetrapod vertebrates from a paleontological perspective” organised by Min Zhu and You-an Zhu, two great colleagues from IVPP in China.

I gave my talk “Morphometric Analysis of Lungfish Endocasts Elucidates Early Dipnoan Palaeoneurological Evolution” from the comfort of my own office in Adelaide, Australia, on early brain evolution of fossil lungfish (one of my absolute favourite topics in the world!) I can’t say much more about it right now as I’m preparing a paper for submission soon on this very topic.

There were some great talks in our session, but I especially enjoyed the work from Xindong Cui (also from IVPP) on new material of Youngolepis, a lungfish-like fish from the Lower Devonian of Yunnan, China. I look forward to seeing his work published soon!

National Science Week 2021

National Science Week 2021 is fast approaching! During 14-22 August Australia-wide there is a plethora of science-themed events, tours and more for you to get involved in.

I’m involved in a few different events happening during the week:

I’m attending the Official Launch Lunch being held at the South Australian Museum with Mr Brian Oldman, (Director of the South Australian Museum), Hon David Pisoni MP and Prof Caroline McMillen AO, (Chief Scientist for SA), in a celebration of science (la di da!)

Secondly, I’m an invited speaker at Seeing Things Differently held by Micro-X at Tonsley on Friday 20th August where I will present my talk ‘A virtual revolution for fossil hunters – how CT scanning is transforming palaeontology’ to registered school groups coming by for a tour of Adelaide’s Micro-X factory.

I’ve been invited to be part of a fun night of science and cheeky debate between four teams representing different STEM fields called My Science Rulz, Your Science Droolz. It’ll be a battle between palaeontology, astronomy, maths, and neurogenetics on Tuesday 24th August at The Gov and should be a good laugh.

And lastly, I’m helping to organise an event being put on by the Royal Society of South Australia, thanks to support from Nat Sci Week, called the Royal Society Show Case Science to celebrate and promote to the public the diverse research our members undertake to advance knowledge in SA. The night will include lightening talks and distinguished panellists making their case for science on Wednesday 18th August. This event will be held in person at the SA Museum, but guests are also available to join in online and attendance is free! Please check it out. #ScienceSouthAustralia

So it is shaping up to be a busy, but fun-filled and science-y week! I urge you to check out the website to see if there is an event that tickles your fancy so you too can get involved.

100 years of fossil brains

2021 marks 100 years since the birth of palaeoneurology, the study of “fossil brains”. As its name suggests, palaeoneurology combines the study of fossils with neural evolution.

On this day in 1921, a young vertebrate palaeontologist from Frankfurt, Germany, Johanna Gabrielle Ottilie “Tilly” Edinger, submitted her thesis describing an “endocast” of a Mesozoic marine reptile, Nothosaurus. An endocast is a mould of the internal space of the skull which houses the brain; these can form naturally via sediment infill, or can be recreated using virtual models.

To mark the occasion, I wrote an article for The Conversation. Please follow this link to read it: “Remembering Tilly Edinger, the pioneering ‘brainy’ woman who fled Nazi Germany and founded palaeoneurology“.

I was inspired to write this article following conversations with Dr Susan Turner (co-author of “Rebels, Scholars, Explorers: Women in Vertebrate Paleontology“).

Tilly Edinger’s pioneering work has allowed us to understand much more deeply the evolution of the vertebrate brain, and continues to inspire other researchers to carry on her important legacy.

I’ve included a list of some active “brainy” women currently working in palaeoneurology below if you would like to learn more about specific groups of vertebrates (I guess it can’t be fish all the time!)

EEE talk: Fishy brains and fossil endocasts

I’m excited to be giving the next Ecology, Evolution & Environment seminar at
Flinders University on Tuesday 8th June 1pm ACST. I’ll be talking about: “Fishy brains and fossil endocasts: early vertebrate neural adaptations to life on land.”

Come along in person or join in online (https://video.flinders.edu.au/events20/21/EcologyAndEvolutionSeminarSeries.cfm?id=2). You can even submit questions to me live via www.slido.com using the event code #S3E_Clement.

The Backpacker’s Guide To Prehistory

Have you ever wondered what travel essentials you would need to pack for a journey back in time? Who has the best tips for things to see and do (and avoid!) from throughout earth’s history? Are you considering a journey back in time to the Devonian? It’ll be lovely and warm so pack your swimwear, but don’t forget your shark diving cage and oxygen tank is all I can say!

I had lots of fun recording an episode of a new podcast called “The Backpacker’s Guide To Prehistory” which is the brainchild of David Mountain. David invites two experts on various geological periods to each episode to learn about the “top travel tips for time travellers”. It is a fun and interesting way to learn about the past.

Download the whole series from wherever you get your podcasts. Or simply click below to listen to the Devonian episode to learn about placoderms, tetrapods, the first forests, giant fungi and the end-Devonian extinctions.

VP fieldtrip to Victoria

I was back in the office after a week away on the Flinders University 3rd year Vertebrate Palaeontology field trip to Victoria (in south-eastern Australia).

First, we explored some Silurian and Devonian deposits in the Grampians (Gariwerd on Jardwardjali land), including some spectacular trace fossils from the Glen Isla Quarry and Homestead, whilst camping at the beautiful Buandik Campground.

Silverband Falls, Grampians N. P.

Next we moved on to Mansfield in the foothills of the Victorian Alps (Taungurung) to work on the Kevington Creek Formation of the South Blue Range (mid-Devonian), and the Devil’s Plain Formation (Carboniferous).

View from South Blue Range, Mansfield

These sites were relatively productive with us discovering many plant fossils (e.g. Lepidodendron), placoderms (including Bothriolepis, Groenlandaspis and Austrophyllolepis), and some tiny sharks teeth from Kevington Creek Formation.

I was pleased to find a block containing what looked like skull roof bones from a rhizodont (Barameda), a large predatory fish known to come from the Carboniferous deposits of “Fish Hill”. We also found numerous large spines from acanthodians (“spiny” stem sharks).

Lastly, we jumped through time on our way home to the Pleistocene of Warrnambool on the Great Ocean Road of western Victoria. There we saw megafauna trackways (including those from the marsupial “lion”, Thylacoleo) at Thunder Point and heard about human habitation of the Moyjil and Tower Hill area from >35,000 years ago, and possibly as long ago as 120,000 (!) from Dr John Sherwood.

Thunder Point, Warrnambool

We were so lucky to be able to run our fieldtrip this year after two failed expeditions last year (COVID-related). We got to visit some truly spectacular places, and found plenty of fish fossils so all in all, a great success, I’d say!

Another brainy paper

It has been a good month with another paper published last week. This one “Brain Reconstruction Across the Fish-Tetrapod Transition; Insights From Modern Amphibians” forms part of a special research topic in the Frontiers in Ecology & Evolution journal on soft tissue reconstruction (you guessed it!) over the fish-tetrapod transition.

I was very happy, along with my co-authors, to contribute to this special issue. My co-authors included Flinders PhD candidate, Corinne Mensforth, Dr Tom Challands from the University of Edinburgh in the UK, Prof. Shaun Collin from La Trobe University (Victoria, Australia) and Prof. John Long, also from Flinders University.

In this work we looked at the relationship between the brain and it’s “endocast” in some amphibians (frogs and caecilians), to compare with earlier work on lungfish and salamanders. The endocast is a cast or mould of the internal space of a hollow structure, in this case, the space inside the skull that usually houses the brain in life.

We did this to try and better inform our interpretation of fossil endocasts when the soft parts of the brain haven’t been preserved and only the hard, bony parts remain. I also wrote an article for The Conversation about this research, so if you’d like to know more please CLICK HERE!
