Many animals can reshape and shed their teeth – and now scientists have traced this ability back 380 million years #Bullerichthys #GogoFormation #Devonian theconversation.com/many-animals...

“Trait-space disparity in fish communities spanning 380 million years from the Late Devonian to present”, published now in Palaeogeography, Palaeoclimatology, Palaeoecology, comparing trait space occupation between 3 Late #Devonian communities with modern ones www.sciencedirect.com/science/arti...

New paper out yesterday "New specimens of the arthrodire Bullerichthys fascidens Dennis and Miles 1980 show incipient site-specific osteichthyan-like tooth addition and resorption" Read it now in Swiss Journal of Palaeontology: sjpp.springeropen.com/articles/10....

Visualizing this as a morphospace, we see the lungfish jaws (on the right) are much thicker and stockier compared to ray-finned fishes (lower left). 11/15

If we look at jaw shape as a morphospace thru time, we see lungfish (Dipnoi) burst out of the gate during the early Devonian, leaving the ray-finned fishes, and most of their lobe-fin relatives, far behind. 9/15

When we compare how fast/slow these jaws are evolving, we find a neat pattern. Devonian lungfish really stand out with their super fast rates, while early ray-finned fishes are comparatively very slow. 8/15

"Macroevolutionary role reversals in the earliest radiation of bony fishes", led by @fishfetisher.bsky.social Emily Troyer & Rafael Rivero-Vega in Current Biology examines 86 species of early bony fishes to examine shape variation, rates of evo & Mech Adv through time. www.cell.com/current-biol...

Excited to announce that the 1st paper from my postdoc is now out in @currentbiology.bsky.social ! Using a large dataset of 3D preserved fossils, we explore the diversification of jaws in early bony fishes. 1/15 www.cell.com/current-biol...

Fossil claw prints found in Australia were probably made by the earliest known members of the group that includes reptiles, birds and mammals The findings suggest that this group — the amniotes — originated at least 35 million years earlier than previously thought https://go.nature.com/4j6rhMB

Nice coverage in @theguardian.com here: www.theguardian.com/science/vide...

Thrilled to announce our latest paper, published today in @nature.com on the oldest fossil amniote trackways, from the earliest Carboniferous of southeastern Australia. www.nature.com/articles/s41...

It's out! We describe probable reptile tracks from the earliest Carboniferous of Australia. This pushes the amniote record back by some 35-40 million years and implies that the tetrapod crown group originated deep in the Late Devonian. The paper is Open Access. 🧪 www.nature.com/articles/s41...
