Welcome Ammonitritor scientacivium, a new Early Triassic omphalosaurid from Svalbard! 🤩 The new skull confirms omphalosaurids were a group of specialised pelagic ichthyosauriforms that likely fed on ammonoids. New paper is out now in Biological Reviews! onlinelibrary.wiley.com/doi/…
ALT Fossilised skull, skull reconstruction and life restoration of the new omphalosaurid Ammonitritor scientacivium.

🚨NEW STUDY DROP🚨
A new juvenile specimen of Hupehsuchus, a marine reptile related to ichthyosaurs with a platypus snout and "baleen" teeth, has been described from the uppermost Member II of Jialingjiang Fm of Hubei, China. Helps better understand ontogeny.

NEW AMPHIBIAN - Synorerpeton
New albanerpetontid is described from a bunch of teeeeeny lil bonez from Maastrichtian Spain! These were salamander-shaped amphibians that were not closely related to living salamanders

New paper in Ameghiniana! 🐊🦴 Led by Juan Ruiz, we digitally reconstructed the jaw of Sahitisuchus fluminensis, a sebecid crocodyliform from the Eocene of Brazil.
This is the unedited postprint (accepted version).

New specimens of Kronosaurus for #FossilFriday
While I was in Queensland earlier this year for the awesome Queensland Dinosaur Week, I sat down with David Elliott, founder of the Australian Age of Dinosaurs.
Watch the full chat, here:

This is Dubreuillosaurus.
Known from one fossil, the holotype. Described in Journal of Vertebrate Paleontology in 2002. Accessioned into France's national collection, the Muséum national d'histoire naturelle in Paris, as MNHN 1998-13.
Now up for auction. HOW IS THIS POSSIBLE?

Humans are far more prone to degenerative skeletal diseases than other apes. Our new @Nature paper uncovers the genetic changes that shaped our skeleton and uncovers a major clue to why it is so vulnerable to degeneration.🧵👇

I am excited to announce Invictibellatrix amberina, the first megaraptoran from Europe (Wessex Formation, Isle of Wight)
The name means unconquered warrior (in the feminine), with the species name being after Amber.
