A few quick color pencil sketches I’ve made of Allosaurus, including Big Al, the actual fossils of which I once saw when I visited the Museum of the Rockies one day, resting at the bottom.

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.

A partial dinosaur tooth of an indeterminate theropod, possibly an early abelisaurid or allosaurid from the Isalo III Formation in Ambondromamy, Madagascar. The tooth has a serration density of around 16/5 mm on both carinae which rules out a misidentified Cretaceous aged Majungasaurus crenatissimus. The morphology has some resemblance to that of premaxillary teeth known from abelisaurids and Allosaurus.

Memory versus Reference time! And yes, this is my new sketch of allosaurus fragilis with colored pencils from sketchbook app. #paleoart #sketchbookapp #allosaurus #allosaurusfragilis #coloredpencil #myart #allosauridae #carnosauria #theropoda #dinosauria #dinosaur https://www.instagram.com/p/CmE2-Xrr20h/?igshid=NGJjMDIxMWI=

Veterupristisaurus: Old shark lizard.

Milneri: honouring paleontologist Angela Milner

-Veterupristisaurus was a member of the Charcharodontisauridae family from Jurassic Tanzania

-the holotype contains an isolated caudal vertebra, two posterior partially fused middle caudal vertebrae, and an anterior caudal vertebrae. Basically just a bunch of pieces of the spinal column for those who aren’t proficient in anatomical terms.

-these continue to be the only bones found.

-the animal was originally named as Ceratosaurus, but it has been decided they are different animals.

-even though there’s been a lack of bones found, there is no current debate on whether Veterupristisaurus is synonymous with another non-avian dinosaur.

Portrait of tetanuran Asfaltovenator vialidadi from the Lower Jurassic of Argentina. The holotype of this theropod was discovered in 2002 in the sediments of the Cañadón Asfalto Formation and extracted in 2007. The specimen is represented by a skull with a lower jaw and a partial postcranium. The Asfaltovenator is characterized by a mixture of features of early theropods and more progressive tetanurans. It was originally classified as a basal allosauroid, but in 2024, Andrea Cau placed it next to Sciurumimus in the megalosauroids. At the same time, according to the results of other analyses, the closest relative of the Asfaltovenator was the later Allosaurus. Asfaltovenator was a large animal about 8-9 meters long. It co-existed with a number of other theropods, including Piatnitzkysaurus and ceratosaur Eoabelisaurus.

Jurassic June 2024 Day 30: Allosaurus fragilis

[mesozoicmarket]

A partial dinosaur tooth of an indeterminate theropod from the El Mers Group in Boulahfa, Boulemane, Morocco. The tooth notably shows pronounced interdenticular sulci or grooves in between the denticles on the distal carina. The short mesial carina could suggest a megalosauroid, but could also be a basal allosauroid as well.
