This Fossil Friday is a blast from the past! Snapped circa 1988, this photo depicts Tyrannosaurus rex and Triceratops on display in the Museum’s Hall of Late Dinosaurs. These iconic dinosaurs are still on display at the Museum, but they now sit in separate halls. You can find T. rex in the Hall of Saurischian Dinosaurs—saurischians are characterized by grasping hands, in which the thumb is offset from the other fingers. Triceratops is in the Hall of Ornithischian Dinosaurs, which displays dinosaurs that are characterized by a backward-pointing extension of the pubis bone. This bone was thought to have helped support the enormous stomachs that these animals needed to digest masses of tough vegetation!

Have you ever drawn a Velociraptor? Just wondering because I love them so much and your artwork. 💚

I love drawing dinosaurs, but I don't think I've drawn a Velociraptor yet! Let's fix that.

Here's a Velociraptor mongoliensis taking a nice stretch after a nap.

Artwork of the Plateosaurus from the Zoo Tycoon: Dinosaur Digs DLC.

It's a very primitive sauropod relative from the Triassic Period and was considered one of the largest dinosaurs of that era. Its bipedal stance contrasts the appearance of its eventual sauropod descedants.

AWMM-IL 2022.21 “Barbara” is a Tyrannosaurus Rex skeleton unearthed from the Hell Creek formation in Montana, recently on display at New Zealand’s Auckland War Memorial Museum. She is best known for possibly being pregnant, assumed due to the presence of medullary bone tissue, and for a catastrophic metatarsal injury which would have rendered her unable to hunt while recovering and with a noticeable limp afterwards, but which was clearly healed. The implications of her survival through such an injury are fascinating, but any formal papers on Barbara will be long in coming as she has returned to her private owner since her exhibit closed at the end of 2023.

Siamraptor

Siamraptor was a genus of carcharodontosaurian dinosaur from the Early Cretaceous period. Its type species is S. suwati. The holotype was found in the Khok Kruat Formation in northeastern Thailand. Siamraptor is the first and currently only definite carcharodontosaurian known from Southeast Asia.

"Siam" is derived from the original name of Thailand, "raptor" is Latin for robber, and the specific name suwati refers to Suwat Liptapanlop, a supporter of the Northeastern Research Institute of Petrified Wood and Mineral Resources.

Its autapomorphies include a jugal with a straight ventral margin and a deep anterior process below the orbit, a surangular with a concavity and four posterior foramina, a groove along the suture between the surangular and prearticular, an articular with a formen at the suture with the prearticular, a cervical vertebra with an additional foramen that is excavating the parapophysis, and the presence of a pair of foramina at the base of the neural spine on the cervical and posterior dorsal vertebrae. Another possible autapomorphy specific to the genus may be a deep concavity excavating the posterior end of the lateral shelf.

Siamraptor is known from its holotype, consisting of a posterior right mandible including the surangular, prearticular, and articular; as well as referred material from three other individuals including three right premaxillae, a right and left maxillae, a left jugal, two posterior parts of the left mandible, three cervical vertebrae, a caudal vertebra, a manual ungual, a right ischium, a section of the left tibia, and a left pedal phalanx. Siamraptor was recovered as a definite carcharodontosaurian, though its relationships within the clade are uncertain. It may have been a derived member of Allosauria outside of Allosauridae or a basal member of Carcharosauria in a polytomy with Eocarcharia, Concavenator, and Neovenator.

Reconstruction of the early dinosaur Herrerasaurus ischigualastensis from the Late Triassic (Carnian stage) Argentina. This genus was described by Osvaldo Reig back in 1963, but due to the fragmentary nature of the bones, the classification of the animal was controversial (opinions were expressed that it was a prosauropod or even a dinosaur outside the two main groups). Only in 1988 was a complete skeleton with a skull found, which allowed reconstructing the dinosaur and its approximate kinship. However, it is still unclear whether Herrerasaurus was an early theropod or whether it was closer to sauropodomorphs. The remains, named Ischisaurus cattoi and Frenguellisaurus ischigualastensis, were later assigned to Herrerasaurus.

Herrerasaurus is interesting for its rather large size for an early predatory dinosaur: some specimens of "Frenguellisaurus" reached 6 m. The skull was relatively small, but the jaws carried sharp saw-toothed teeth, including "fangs". There was also a shock-absorbing joint in the middle of the jaw, which allowed holding large prey. The hands were armed with three grasping fingers, and the longest of them was the third. The rudimentary fourth and fifth fingers were hidden by soft tissues. The pelvis of a Herrerasaurus is unusual. Only two sacral vertebrae fused with it (at least 3 in other dinosaurs), and the acetabulum was not completely open. At the same time, the pubic bone was directed not forward, but backward, as in maniraptorans, and carried a massive "boot". At one time, this served as the basis for Gregory Paul to designate the herrerasaurs as an early group in which bird-like features arose, and even to bring them closer to the "protoavis".

In this work, I tried out a style with shading using a black pencil, not a pen. It is much easier to apply shadows with a pencil, and I liked the result. It shows an extensive cover of filaments inspired by a possible "fluffy" ancestral state for ornithodirans (dinosaurs, pterosaurs and small groups close to them).

I’ve been looking at skeletals for theropods throughout the Mesozoic and what really stands out to me is how quickly (evolutionarily speaking) early carnivorous Saurischians went from having five fingers to three. Meanwhile the hallux, which you would think would be vestigial, remained present on theropods even up to today where they’ve been beefed up and used for grasping. What where non-avian theropods using their halluxes for that kept them from shrinking into nothing? Most of them where terrestrial and flightless and still had them, meanwhile ratites are also terrestrial and flightless and have lost them. And why are three fingers better than five on predators? Is it because archosaurs only have three claws on their hands anyway, so the other two digits just get in the way? But why do Abelisaurs, whose arms are completely useless, have four fingers??

Day 8: Mussaurus

A adult version of its kind. In the past, the adult specimens were considered to be unknown for a single specimens of referred to a infant, but now thanks to latest discoveries, they are now fully recognized as new and only species of 2020s.

The early sauropodomorph Camelotia traveling on a quest

This was a study on a shot from The Green Knight, saw that movie last week finally and absolutely loved it So what do I do? Slap a dinosaur in there, as one does

What are your opinions on the Carnotaurus? Also, what is your favorite dinosaur?

I love carnotaurus! Such a unique and interesting dinosaur. I've always been drawn to hadrosaurs, though. My favorite dinosaurs are (in no particular order) shantungosaurus, olorotitan, dreadnoughtus and sauroposeidon.

Here's a carnotaurus! I've never drawn one before.
