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.

The PNSO Tylosaurus is very good, although also expensive!

My depiction of the possible causes of the caimanine tooth marks on a terror bird bone found in Colombia, by scavenging and by active predation.

If you see this, post a Dino! 🦖

Here's the Colombian sauropod Padillasaurus.

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.

It's an pteraspidid "fish".

Indeed.

An addition to the skull of the ancient manatee Potamosiren (Miocene from Colombia): the lower jaw in a upper view, to give a better idea of the volumen of the head.

A full color and hypothetical reconstruction of the head of recently found Dimartinia, based more or less in small sparassodonts as Cladisictis and Lycopsis for proportions. Interestingly, the mandible looks tiny compared to the teeth.

A reconstruction of Dimartinia pristina, a small sparassodont from the Cerro Azul Formation, Argentina (approx. 9 million years ago). It shares features with the strange thylacosmilids, the sabertooth lineage of sparassodonts as Thylacosmilus, but it doesn't have the specialized mandible.

Since that a recent paper indicates that remains of megafauna of Brazil suggests that some members of it, as the camelid Paleolama survived until the Holocene, is interesting to consider the idea that some rock paintings from there are also inspired by these late survivors.

Happy holidays too!

Just a quick drawing, wishing all of you a Happy Christmas and the best for 2025! This is inspired by the recent discovery of tooth of Globidens in Colombia, which inspects a curious sell of an ammonite. 😉

No, I but I have this compilation of all the issues.

This time, here is the skull of the primitive manatee Potamosiren magdalenensis from Colombia. Named from a partial lower mandible and some molars, since then it has been recovered additional teeth and a piece of maxilla with upper molars, which was assigned to the dugong Metaxytherium.

First post here. Nothing better to start than the fire beast, Pyrotherium!
