An unusual high-spined dinosaur from the Kem Kem, it's Spinosau- oh wait, it's Rebbachisaurus, a medium-sized diplodocoid sauropod. I based much of this reconstruction on related species, such as Lavocatisaurus and Limaysaurus. Size comparison below ⬇️

After four months and 36 illustrations, I present the final Kem Kem chart – a look at of one of the most incredible ecosystems the world has ever seen.

Short thread below!

A dinosaur tooth of a diplodocoid sauropod, possibly Rebbachisaurus garasbae from the Kem Kem Group in Taouz, Morocco. There's more than one morphology so it's difficult to say which teeth belong to this rebbachisaurid species. #FossilFriday

Day 26 of #dinovember 🦖
Rebbachisaurus garasbae from late Cretaceous shared it's habitat with another sail-backed dinosaur found in the Kem Kem beds, the Spinosaurus aegyptiacus. So what was with North Africa that made two huge dinosaurs develop sails?

Photo of artwork on a sketchbook with pencil and eraser on its side. The grayscale drawing shows a sauropod dinosaur Rebbachisaurus dwarfing the trees around it. In front of the sauropod, equally large Spinosaurus walks past. Two smaller Deltadromeus hide in the foliage in the background.

Day 26: Rebbachisaurus!

Fun fact: This sauropod is known for its unusually tall ridged back that may have supported heavy muscle attachment or a sail for display. I went the display route, of course. :)

And that's the second largest dinosaur in the ecosystem - not quite as impressive as the titanosaur, but nonetheless very cool and that tail stretches right across the scene.

#dinovember2024 #paleoart #dinosaur #sauropod
A Rebbachisaurus peeks upwards through the leaves. The dinosaur is in perspective with the head closest to the camera, and lifting slightly up to potentially reach some lower branches. The viewpoint is as if the viewer is sitting in the tree above. The sauropod is mostly varied shades of brown with both dapples on the shoulders, and stripes along the spine, and ringed legs. The head is a bright shade of blue, with orange spots along the forehead. It has a reddish neck directly by the face, and another reddish marking by the eye.

It is hard to get a size for a lot of these fragmentary pterosaurs - I've gone for a tentative 4-5ish metre wingspan here.

My 25 years of palaeoart chronology...

The result of the paper about my 2011 "Double Death" artwork was: two #Carcharodontosaurus could carry 850kg. This would be a 8.5m long juvenile #Rebbachisaurus, pictured here in version 4...

The running pose was very much a tribute to one of Todd Marshall's many incredible crocodylomorph depictions from the early 2010s. Thanks again to Armin Reindl for croc-advice!

This is one of the tiniest of our animals so far, I think only beat out by Leptostomia. Big thanks to @arminreindl.bsky.social for help with some anatomy details!

This is the smallest dinosaur here! I'm certain there must have been birds around, but as far as I can tell, no fossils have been found, or at least, none have been clearly identified.

Not quite the 12m wingspan giant from 1999, we now think Ornithocheirus has a much more reasonable, but still impressive, 4-5m wingspan. Also - I've rearranged a few animals in the size chart for a better flow!

Day 26 of #Dinovember! The sail back sauropod Rebbachisaurus! #Dinovember2024 #Paleoart #Dinosaurs
The late Cretaceous sauropod Rebbachisaurus! They are distinguished from other sauropods by their unusually tall, ridged back and the spine or sail that lay atop their back. It also had a whip-like tail. The color is inspired by Ocellated Lizard; an emerald green body with brown spotted patterning along it's back. It has striped light green underbelly and at the end of it's tail. It's tongue and mouth are an indigo

While it's our smallest aquatic critter so far, it's still pretty sizeable at around 2-3m in length. Jeremy Wade would have the time of his life in the Kem Kem.

With such fragmentary material, like many of these pterosaurs, it is hard to get a size estimate, but I've tentatively sized this critter to a 3-4m wingspan.

While not larger than Elosuchus, Laganosuchus is still a pretty hefty addition to the roster. I'm finding it trickier to come up with a clean composition for the aquatic section - something I'll keep working on.
