Update on the Green Waterhole Cave #fossil #mammals kangaroo Simosthenurus occidentalis #paleoart skeleton recon.

@zieglertn.bsky.social @toothygrinart.bsky.social @p-hazael.bsky.social @isaacarkerr.bsky.social 🧪thoughts welcome - any comments?
The Green Waterhole Cave Simosthenurus occidentalis specimen - an extinct 'short-faced kangaroo' - housed at the South Australian Museum. The specimen has been photographed and digitally articulated and posed to try to reconstruct the animal. These kangaroos have large, heavy, short heads. Long arms with four-fingered hands, of which the index and middle fingers are very long with exceptionally long claws. Very short back legs for a kangaroo, with rather short feet with only one giant toe ending in a hoof-like claw. They are very mysterious, with analyses and trackways suggesting they may have walked on two legs instead of hopped. If only they had stayed alive for another 50,000 years we could have asked them.

So, hi guys, looks like PhD students are at perlil of having their futures derailed, and Leicester (the birthplace of Charnia fossil) loosing the status of a palaeontology hub. If have a spare second, sign up.

For some time now I’ve been interested in what the glyptodonts – a group of highly modified, large or gigantic armadillos – looked like when alive….

Here’s a sketch of the newly described basal plioplatecarpine mosasaur, Oneirosaurus caballeroi, from the Coniacian beds of Lebrija, in Central Colombia. This sketch was made in honor and in memory of one of the authors of the paper, María Euridice Páramo Fonseca.

Tyrannosaurus "Wilson" figure from PNSO. Here it with a brand new base that includes a skull of a crocodylian (Borealosuchus) and other details. Also, for this figure it was made a repainting in the teeth, mouth and the dark stripes. I want to thank to Jorge Moreno Bernal for his work in this piece.

A reconstruction of Pitheculites chenche, a small marsupial from the Miocene of La Venta (Colombia). So far, only it has been found a piece of the lower jaw. Pitheculites belongs to the abderitids, close relatives of the shrew-possums (caenolestids). It has a large blade-like first molar.
