Research out that I was involved in at the @nhm.org under the @chalksea.bsky.social project!

I had a great time sampling chalk specimens for this project.

Congrats @plesiosarahs.bsky.social and co.!!

As well as @plesiosarahs.bsky.social,
other authors on this study include:
@jdwitts.bsky.social
@marcehjones.bsky.social
@dntangunan.bsky.social

She now has a trace fossil named after her:

Images of the trace fossil Osspecus eunicefooteae. The inset shows a post mortem burrow in the bone of an fossilised ichthyosaur (from the Cretaceous of the UK) as seen in a slice from a micro X-ray CT scan. The main panel shows a 3D digital model of the burrow made in specialist software (Avizo) by tracing the burrow slice by slice. The burrow is about 2.7 mm across.

Happy Birthday #EuniceNewtonFoote! 🎂
She would be 206 years old today!

We recently named the trace fossil #Osspecuseunicefooteae after her in this study led by @plesiosarahs.bsky.social on Cretaceous bone-eating worms:

Not a bad homage given that we didn't have much time and it was done from memory.

Sculled 20km of Thames tideway today 😮‍💨 ☀️

Fun afternoon in the tank room with the great white sharks @marcehjones.bsky.social

A group of PhD students posing with a variety of skull casts. Some of the PhD students look more normal than others...

PhD dream team (including @lej-palaeo.bsky.social and @plesiosarahs.bsky.social) from the NHM stand at the #lymeregis #fossilfestival. We had an amazing weekend talking to everyone about fossils!

The earliest fossil cetacean with Osedax borings: narrowing the spatiotemporal gap between Cretaceous marine reptiles and late Cenozoic whales | Royal Society Open Science Borings of the extant bone-eating worm Osedax have previously been found in Cenozoic cetaceans and Cretaceous marine reptiles. The stratigraphically youngest Cretaceous example is from the Maastrichti...

And that’s the fourth and final chapter of my PhD published! More wormholes in whale bones, including earliest cetacean occurrence with three ichnospecies.

Squaring early, missing the catch 😇 .. lots of splash as a result

Best way to spend a summer evening. Bonus points if you can spot the flaw in form that made my coach take this video from the launch to show me.

“What will you do when you finish writing your thesis?”

The Thames gifted me another fossil sea urchin this morning.

Bank holiday weekend mood

Apparently I'm at the stage of my career where random men I don't know email me and explain in a patronising tone things I already understand and then get upset when I don't reply. Quite enjoying continuing to not reply.

Later today for
#GenerationHope
at the NHM UK.

there has been something of a fox development 🦊🦊🦊

Among the thousands of dire wolf specimens at La Brea #TarPits is this 𝘈𝘦𝘯𝘰𝘤𝘺𝘰𝘯 𝘥𝘪𝘳𝘶𝘴 lower jaw. Known as “The Endling”—the last known #direwolf fossil on Earth—this fossil is dated to be approximately 13,082 years old.

See the fossil now on view in our Fossil Lab!

I don’t always follow the thought process of reviewers, but when I don’t I really don’t.

Also now available are the titles of the four (!) special symposia at #2025SVP:

- Ancient Biomolecules

- Synchrotron radiation micro-CT scanning in paleontology

- Evolution of Triassic non-marine tetrapod communities

- Multidisciplinary approaches to skull function and evolution

Abstract submission is now open for #2025SVP in Birmingham! Deadline is June 3rd & all key information is here:

For #FossilFriday a lightly metamorphosed limestone with mineral-infilled burrows, crinoids, and bivalves, showing small-scale faulting. Found in a Spanish riverbed.

A juvenile kittiwake in the hand, wearing a 3-digit coded yellow colour ring, a red plastic ring and a metal ring.

Listen up anyone working in the Irish Sea this summer! We tagged a bunch of kitts in Liverpool Bay and want to gather as many resightings as we can. If you spot these yellow colour rings please give me a shout (dla205@exeter.ac.uk) 🐦💍💛
