Nature Restoration Law has been adopted by the European Parliament 🎉🎉🎉 We have defeated the attempts to block action on climate change and biodiversity loss. I am bowled over.

Ok! FINALLY! Here is the first one. Concept art of Mortuneria I did for Prehistoric Planet 2. Adult and juvenile. It was so much fun to work on this taxon

Had an amazing time NaturalHistoryDK over the last few days looking at weird, fascinating cephalopod🦑 fossils from the Cretaceous of Denmark! Thank you Laura Cotton, Emma Sheldon and Dr. Adiel Klompmaker Dr. Adiel Klompmaker @paleoadiel.bsky.social.bsky.social for the wonderful chats, was great meeting you there!

Belated but obligatory post-conference tweet! Had an amazing time at #PalAss23 presenting some of my research on Cretaceous #Cephalopods and #Mosasaurs 😁 Thanks to The PalAss and all the organisers for an amazing conference, and my EarthSciences UCL friends for the amazing company!!

#FossilFriday Went to British Antarctic Survey 🐧 to take a look at cool marine Cretaceous-Palaeogene fossils from Antarctica! Highlights were giant ammonites, mosasaur bits and pieces, and drawers full of echinoderm fossils 😁 Thanks for the great chats Rowan Whittle, James W and Ming Khan!😊

Ragnarok has arrived - happy #MosasaurMonday! It is my pleasure to introduce JORMUNGANDR WALHALLAENSIS, a new mosasaur from North Dakota! I’ve worked on Jorgie with Clint & Nathan for the past ~1.5 yrs & I am BEYOND stoked to finally share it with everyone! All🎨 Hank Sharpe

My favourite image from my recent Lake District trip. Stuck it out in this spot for the better part of two hours waiting for some light and really pleased that I did. I absolutely love this view, encapsulating everything best about the Lakes

Exciting new paper: Madison Tripp et al. show endogenous organic matter preserved in #fossil plants from Mazon Creek, incl. diagnostic arborane and fernane compounds. 🌿 ➡️Powerful new approach for resolving plant parataxonomy! #MolecularPaleobiology nature.com/articles/s4159…

Happy #MosasaurMonday! Featuring mosa-models from Princess Aira Buma-at and Raheem Butt, a mug, the Oceans of Kansas book by Mike Everhart, and courtesy of NaturalHistoryDK & Geomuseum Faxe... the majority of the Danish🇩🇰 mosasaur fossil record for me to study🥳

Another new species, another exciting discovery tainted by the use of AI images... Marambionectes is a new plesiosaur genus from Antarctica. Unfortunately, the describing authors resorted to using AI-generated images to promote their research. Not a good look. #PaleoAgainstAI

Cranchiidae has to be one of my favourite family of squids. Cranchiids are funky looking, many are transparent and they have a special chamber filled with ammonium to help them float. #CephalopodWeek

Incredibly excited to be in #Maastricht for the 175th Anniversary of the Maastrichtian conference!! If you're curious about giant cephalopods 🦑, be sure to come to my talk in Centre Céramique tomorrow at 10:35 AM!
