This is the CT-scanned skull of sani, a 190 million-year-old tuatara relative from Arizona, USA. It shows that many tuatara features were already present at a time when dinosaurs were just hitting their stride.

For today I'm particularly excited to present you two stunning specimen of one of my absolute favourite dino: Allosaurus. In photo 1-2 we have A. jimmadseni, while in 3-4 A. fragilis.
The key to tell apart one specimen from the other is the shape of the jugal.

I have an addiction for SEA MONSTER DOLPHINS and sharks. So maybe we can talk about the Cauvery Basin and this ONE site called Karai where the waters were chilly in the Cenomanian and the sea was open and filled with sharks

In remembrance of my friend Markus Bertling, curator of the Geomuseum Münster, who suddenly passed away, I want to share some images of Brancasaurus, a specimen he took care of, for Markus supported my research for many years and I will surely miss him.

A rare bird for Kurt Regschek's 'Urvogel (Archäopteryx)' (ca. 1955). Unfortunately for the select group of palaeontology-surrealism connoisseurs, this painting seems to have been auctioned off with little info.

We've always dreamed of having our own dinosaurs, so that's why we created Kaya's Vale!

After all, who wouldn't want to have 2 tonne, friendly Allosaurus by their side?! 🦖❤️

What would your companion dinosaur be?

Surely one of the most enigmatic of iguanodontians. The skull of Ouranosaurus nigeriensis ( Taquet 1976) showing the strange ornamentation of a pair of bosses at the back of the nasal bones.
