Yesterday, @tweetisaurus.bsky.social visited us @smnstuttgart.bsky.social to talk about her amazing work on Spicomellus, which had everything that makes palaeo great: unexpected discoveries, fieldwork, prep work, bizarre anatomy, CT scanning, you name it

Meet Galahadosuchus jonesi, a new crocodylomorph from the Late Triassic of the UK, described by @es-ucl.bsky.social & @nhm-london.bsky.social PhD student Ewan Bodenham (with @stephanspiekman.bsky.social, @tweetisaurus.bsky.social & Paul Upchurch): anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

I'm really thrilled to see the "Cromhall Croc" finally getting the attention it deserves! Please welcome Galahadosuchus jonesi, named after Ewan's school science teacher, who inspired his love of the natural world โ™ฅ๏ธ anatomypubs.onlinelibrary.wiley.com/doi/epdf/10....

We @journalsystpal.bsky.social commissioned a series of short review articles on the systematics of major fossil groups from leading experts, and asked them to speculate on where their field is going. The first, by Otega-Hernandez, is out now: www.tandfonline.com/doi/full/10.....

Out in @nature.com today, we shake up the ornithischian family tree. Remember those weird Late Cretaceous iguanodontians, the rhabdodontids? Well they're weird because they aren't iguanodontians. They're ceratopsians. Well, at least some of them are... www.nature.com/articles/s41...
Hello from Stuttgart! Never been to the SMNS before but it's a lovely museum with amazing collections. Right now they have a temporary exhibit on Triassic life, featuring Mirasaura. @stephanspiekman.bsky.social showed me round.. Amazing fossils!

Here's Galahadosuchus, a new saltoposuchid from Gloucestershire that I was brought on to illustrate. Congrats to Ewan Bodenham, Stephan Spiekman (@stephanspiekman.bsky.social), Susie Maidment (@tweetisaurus.bsky.social), Paul Upchurch, and Phil Mannion (@pdmannion.bsky.social) on the publication!

New results indicate that rhabdodontids and the previously described Ajkaceratops are actually distinctive European ceratopsians, a group better known from Asia and North America.
