If you are interested in a non-technical summary of our recent paper on how Cretaceous monsoons, tropical cyclones and tides created the exceptional Villaggio del Pescatore dinosaur fossil site, check out this piece I wrote for @theconversation.com: 🦖🌪️ theconversation.com/storms-that-...

Storms that built a graveyard: ancient monsoons created a spectacular dinosaur fossil site

A new study has found that layers in the rock record days, not years, representing storms.

Happy 100th Birthday Sir David Attenborough! We fondly remember your visit to reopen UCL's Kathleen Lonsdale Building, home to our department. Sending our warmest wishes on this very special occasion

Happy birthday to Zofia Kielan-Jaworowska (1925-2015) a Polish #paleobiologist, famous for a series of Polish-Mongolian expeditions she lead from 1963-1971 to the Gobi desert! 🧪🐡👩🏼‍🔬 #histsci There she discovered dinosaurs including the Deinocheirus, plus she & team found the “Fighting Dinosaurs”

My linocut portrait of Zofia Kielan-Jaworowska shows her as in slacks and sleeveless button down with collar turned in a 3/4 view with her right arm extended and left arm bent and resting on the small of her back. She has short hair and appears brightly lit from the left side. In front of her are the Fighting Dinosaurs fossils: a protoceratops and velociraptor entwined. Above her hand is a Cretaceous rodent Catopsbaatar and behind her is a Deinocheirus dinosaur. She is in the field in Mongolia with mountains in the distance. The print is made in a gradient of sandy golden green through dark green-brown through a dark rust from the bottom to the top.

Ecstatic to share my latest published research, the last chapter of my PhD dissertation. 🦕 Iguanodontian dinosaurs may have originated earlier than we thought. 🦖We identified a new clade of 'sail backed' iguanodontians, we formally name it Ouranosauria.

At bottom right is a life reconstruction of the ornithischian dinosaur Iguanodon bernissartensis from the Early Cretaceous (~125 million years ago) of Europe, by Davide Bonadonna (www.davidebonadonna.it).

It was a pleasure for me discussing dinosaur ecology, evolution, and Mongolia fieldwork with you all at ICAL. Great research insights from many of you and thanks particularly to @fossilrob.bsky.social for the hospitality and the precious book gifts! Cheers from Georgie the Gorgosaurus 🦖

Who’s that at our departmental seminar today? It’s the lovely @macroecoevoale.bsky.social wowing us with dinosaurs, ecology, and global science!

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...

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.
