Age constraints confirm antiquity of the earliest Triassic oceanic reptile fossils | Geology | GeoScienceWorld The geologically oldest sea-going reptile fossils occur in Lower Triassic (Smithian, ca. 250 Ma) strata of the Lusitaniadalen Member ([LM], Vikinghøgda

We listened to the critics and completed improved dating on the world’s oldest ichthyosaur locality. New paper out today: pubs.geoscienceworld.org/gsa/geology/...

Aww very nice coverage of our paper. For some context I spent four years going through the 1000 of specimens from the bonebed and STILL find something new and interesting every time I go through it 😂

A hidden diversity of ceratopsian dinosaurs in Late Cretaceous Europe - Nature New results indicate that rhabdodontids and the previously described Ajkaceratops are actually distinctive European ceratopsians, a group better known from Asia and North America.

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...

Dental and Dietary Disparity Among Marine Vertebrates from the Early Triassic (Spathian) of Svalbard – Life Bites the Dust, or A New Hope? - Norwegian Journal of Geology The Early Triassic saw the recovery of ecosystems after the most severe mass extinction event in Earth’s history. However, the ecosystems of the Early Triassic and their patterns of recovery after the Permian-Triassic mass extinction are poorly known due to a scarce fossil record. This study uses dental material to provide information on the taxonomic […]

I guess now would be a good time for my first post here. Yesterday we published a new paper on the incredible ecosystem of tetrapods and other vertebrates in Science. It has been years of work - but we got there in the end. Thank you to everyone the contributed to this work ❤️
