The hidden pattern of the primary teeth in an ancestral ray-finned fish provides a clue to how the strange lungfish dentition could have evolved simply by modifying the growth mode of bone. More information in this newly published piece from @uuvertpalaeo.bsky.social here: doi.org/10.1111/joa....

A team from our lab recently joined fieldwork organised by the University of Latvia, helping to excavate fossils from the Devonian, including armoured fish (Placoderms) and early tetrapods in western Latvia.

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. 🧪

Fossilized claw prints thought to belong to an amniote, an early relative of reptiles, have been found on a slab of rock from Australia dated to about 356 million years ago. The findings in @nature.com, suggest the origin of amniotes is earlier than expected:

It is #TaxonomistAppreciationDay today! A big day for Carl Linnaeus, who we happen to care about (just a little.)
100 years before Darwin's evolutionary theory was published, Linnaeus was classifying animals based on shared traits. He created #SystemaNaturae in 1735, and we still use it to this day!

Among other techniques I spend a great deal of time studying fossils using X-ray or soecifically synchrotron radiation techniques, similar to the methods used in radiology at hospitals to make internal injuries visible.
