Sorry, I haven't posted in a while here!

I usually post on my insta, so I kinda forgot I had this account, be sure to follow me there if you want like weekly stuff.

Heres another Carcharodontosaurid (or at least some of the material is) to add to the collection!

Recently I finally finished this painting of Allosaurus jimmadseni. A lot had to be changed along the way. Even the coloring didn't turn out exactly as it does now; the color of the crests had to be changed. Overall, the result is pretty good, but if I could go back to the beginning, I would do a lot differently. And yes, I initially wanted to make the drawing more stylized than detailed, but I couldn't resist and had to rework it many times.

Allosaurus jimmadseni is one of several species in this genus. It was originally described in a dissertation back in 2000 based on a fairly complete skeleton, but remained invalid until 2020, when a new paper was published. Specimens with pathologies, such as Big Al, were classified as this species. The specimen I drew is largely based on this specimen, but I drew a different set of scars. Allosaurus jimmadseni lived contemporaneously with A. fragilis but occupied a different habitat. It differs, among other things, in the presence of ridges along the nose and the shape of the cheekbone.

Allosaurus anax Danison et al., 2024 (new species)

(Type postorbital [bone behind the eye] of Allosaurus anax, from Danison et al., 2024)

Meaning of name: anax = king [in Greek]

Age: Late Jurassic (Kimmeridgian–Tithonian), between 145–153 million years ago

Where found: Morrison Formation, Oklahoma, U.S.A.

How much is known: A right postorbital (bone in the skull, behind the eye), two vertebrae, and some hindlimb bones. It is unknown whether any of these bones belonged to the same individuals.

Notes: A. anax is based on fossils formerly considered specimens of Saurophaganax, which was thought to be a large theropod closely related to Allosaurus. A new study finds that specimens previously assigned to Saurophaganax actually include a mix of sauropod and theropod bones. However, the authors were not able to definitively classify the type specimen of Saurophaganax (a partial vertebra) as belonging to either a sauropod or a theropod. As a result, they argue that the type specimen lacks distinguishing features that would allow additional specimens to be identified as belonging to the same genus, rendering Saurophaganax a dubious name that should not be applied to other specimens.

Furthermore, the authors found that many of the features that supposedly differentiated Saurophaganax from Allosaurus came from the sauropod specimens once included in the genus Saurophaganax. When only the definitive theropod bones are considered among the former Saurophaganax material, the authors deem it most likely that these fossils represent specimens of Allosaurus. Nonetheless, some of the theropod bones exhibit minor differences from previously recognized species of Allosaurus, such as by being larger (belonging to animals estimated to have weighed over 3.5 tons) and lacking a rough texture on the postorbital. The authors thus classify these fossils as a new species of Allosaurus, A. anax.
