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.

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

Two articles have already been published and like the rest are freely accessible to everyone.

The first two articles both feature art by me, including a skeletal and life reconstruction of Ardetosaurus viator, a new species first published in this volume.

A new giant project on diplodocoids!
When finished, it will provide a look into the anatomy, diversity and phylogeny of these long necked dinosaurs.

They just started a crowd funding campain, so if you want to see this project realized consider donating.

Reassessing the evolutionary family tree and biogeography of the iconic sauropod group Diplodocoidea
We are working on a special open-access volume dedicated to the famed diplodocoid sauropods (like Diplodocus). We aim to publish several papers describing their anatomy, osteology, evolutionary relati...

I wrapped up a summer full of dinosaurs at Paul Sereno's Fossil Lab earlier this week. I had the privilege of working with a lot of great minds, on a lot of great projects.

The vegetation still looks insanely good! 🌿 I can't imagine how long that took to draw though...

Thanks! Those patterns were mostly inspired by leopards and genets. But also by monitor lizards.

Presented a poster today on my research on mammals from a new Lancian microsite.
The poster is in Dutch but don't worry, I'm almost done with the paper which will feature significantly more material anyway.

Here are the original sketches I made last year. At the time I didn't have the intention of turning them into a full illustration but here we are.

The bone core of completer crests were recently discovered in Niger and have not yet been described. This reconstruction is not based on those specimens (in which case I would have made them even taller, especially as they were likely covered by a keratinous sheath).

In case people are wondering about the crest: it is known that Spinosaurus had one, as the base of some have been found. Unfortunately no complete crests have been described, but seeing the extent of displays like the sail and tail, I find it likely the crest was quite prominent.
Reconstruction by Tyler Keillor, Lauren Conroy, Erin Fitzgerald, Paul Sereno.

When it comes to the presence or absence of lips there are valid arguments for both sides. I usually reconstruct them with lips but chose not to this time. Reasons include: interlocking teeth, teeth angling out labially, and tight skin covering on much of the snout.

Scalation is based on other theropods. Wrinkly neck as in Carnotaurus. Larger scales on the feet and square scales in rows on the tail, as in Concavenator. Despite some filaments being preserved on the mostly scaly Juravenator, my Spinosaurus is mostly bald (except for one spot).
Figure featuring cervical skin of Carnotaurus by Christophe Hendrickx and Phil Bell. https://doi.org/10.1016/j.cretres.2021.104994 Jacob Baardse claims to have sculpted the model, but I'm pretty sure he just 3D scanned a dead Carnotaurus found somewhere. Concavenator (this figure and the following two figures) was described by Fransisco Ortega and collegues. https://doi.org/10.1038/nature09181 Caudal scales of Concavenator.
