Triceratops skull Veronica was unveiled at the Oertijdmuseum today! It's very well preserved and probably the most complete Triceratops skull on display in Europe.

Progress on the Oertijdmuseum Edmontosaurus "Monty". Finally uncovered the overlapping tendons on our first block! Nice to see how articulated the bones are on this side.
We have most of the skeleton, but it's in such hard boulders it will take a few more years to finish.

Incredibly sad to hear of his passing.
I and many others won't ever forget him and his musical translation of prehistory.
It’s with heavy hearts we share the very sad news of the passing of the award-winning British composer Ben Bartlett
We would be grateful for your help in sharing this news and celebrating Ben’s extraordinary music and legacy ♥️

Big progress on the Oertijdmuseum Triceratops skull!
It's a little dusty and some pieces have yet to be attached, but it's standing upright. It might just be the best Triceratops skull in Europe.

Meet Spinosaurus mirabilis.
I got to see the material and skull reconstruction in the lab last year. Lots of people have been working hard on getting this described for quite some time and it's great to finally see it published.

Last summers spoils arrived at the Oertijdmuseum today. Lots and lots of dinosaur bones, and even an articulated Edmontosaurus skeleton!

Aurora, a Morrison sauropod composite skeleton. It was recently added to the dinosaur parade at the Oertijdmuseum and is our second diplodocid mount.

Diplodocid bones galore and aplenty at the Oertijdmuseum. Here some photos from a while ago of the construction of Aurora (a composite of two specimens). The skeleton was on display elsewhere for a month and is now being mounted in the Oertijdmuseum. Photos of that coming soon.

I did some more preparation on the phytosaur skull some time ago and finished it up. It now includes more of the right mandible and the tip of the left mandible including the full mandibular rosette.

I can finally share what Triassic fossils I've preparated the past few years! As the new Oertijdmuseum exhibition has opened!
This is, to my knowledge, the most complete adult phytosaur head from Europe.

Sketched this little guy eating a mammal earlier this year, although I didn't actually know what to call it then.
I guess we do now. Welcome back Nanotyrannus!

Two new Edmontosaurus skeletons with preserved skin just got published by Paul Sereno and collegues. They had a fleshy scaly crest over their back and hoofed feet!
I was lucky enough to see the specimens last summer. The publication is open access:

When you're preparing a boring unidentified fossil specimen and suddenly realize it's something incredibly rare and important.

A new diplodocid skeleton was unveiled today at the Provincial House of the Dutch Province of North Brabant!
It will be on display there for the rest of the month, until it returns to the Oertijdmuseum, which is where we originally prepared the skeleton.

The level of texture work I get to do when I don't have to draw the plants.

I haven't been posting much. But that doesn't mean I haven't been drawing any dinosaurs. 👀
