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.

A new study comes from the questions you love to ask. My question "How do vertebral building blocks come together to make different anatomies?" inspired this project ❤️

Back in Sweden to receive my diploma at the Uppsala University doctoral conferment ceremony, followed by a reception at Gustavianium and banquet at the Castle was incredibly special. I think it is only now dawning on me that I really did it, I really am Dr Melanie During.

Out Now in Nature! Amniote tracks from Australia push the timeline for terrestiality back 35 to 40 million years, with implications for our understanding of tetrapod evolution.

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:

When it comes to understanding when animals first walked on land, finding footprints of animals that literally pressed their feet into the ground absolutely holds the key.

#StGeorge and the Pterodactyl (1873), by Benjamin Waterhouse Hawkins of @cpdinosaurs.bsky.social fame, to illustrate his suggestion that #dragon 🐲 legends may have been inspired by encounters with living pterosaurs #StGeorgesDay

Not sure how the octopus fits in 🐙

An old monochrome painting of a knight, Saint George, mounted on a horse about to clout a nearby pterosaur on the head with a mace. The setting is Fingal's Cave on the island of Staffa in Scotland, with columnar basalt all around. For some reason an octopus beneath the horse also appears to be aiding the pterosaur in its fight.

It is a very happy #fossilfriday as I sent back a revised manuscript last night, a years-in-the-making review that is the reason I find my phone full of pictures like this every time I've been to a museum:

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!

Systema Naturae, a double page spread chart, tightly packed with names of animal species. It is split into Quadrapedia, Aves, Amphibia, Pieces, Insecta and Vermes.

New paper released! Chapter 5 of my PhD, co-led by Jordan Matelsky.

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.
