Commission - Australovenator wintonensis



My first commission. :) Australovenator wintonensis for :iconnazrindi:. This theropod has long been on the list of taxa that I would like to draw, and now I have such an opportunity. :D

Australovenator is a representative of a very well-known in paleo-circles group of theropods, megaraptorids. It was described in 2009 from a partial skeleton from the Cenomanian of the Winton Formation, in Queensland (Australia). The holotype was nicknamed "Banjo" in honor of the Australian poet and journalist Banjo Paterson. The skeleton was found together with the remains of the sauropod Diamantinasaurus matildae and consisted of a tooth bone, teeth, ribs, gastralia, partial forelimbs and hind limbs and a partial ilium. The bones of the holotype were described in detail in different years.

Like other megaraptorids, Australovenator was a theropod of a lightweight build, with large muscular "arms" and an elegant skull. The well-preserved material of the limbs allowed paleontologists to study their biomechanics. A biomechanical analysis conducted in 2015 revealed an unexpectedly large humerus range of motion, comparable to that of the dromaeosaurid Bambiraptor. The radius could slide relative to the uln when bending the arm, which allowed changing the plane of the hand. Finally, as in Allosaurus and Dilophosaurus, the fingers were able to bend outwards strongly. All together, this indicates the use of" hands " in hunting. The Australovenator grabbed the prey with his hands and plunged large claws into it with the first two fingers, piercing and tearing the internal organs. The hyper-extension of the fingers allowed to withstand the resistance of the prey. The mobility of humerus suggests that, unlike, for example, Allosaurus, an Australovenator could bring prey with its forelimbs to the mouth. The jaw was long and thin, with small cutting teeth, which also confirms the dominant role of the forelimbs in obtaining food. As for the legs, in 2016, the mobility of the foot was analyzed on the basis of a modern emu. The study showed the dependence of the range of motion on the presence of soft tissues (with them it turned out to be less). In addition, the soft tissues of the foot were reconstructed. Thus, the Australovenator is one of the most studied megaraptorans. It was part of a very diverse fauna, among which were sauropods, ankylosaurs and ornithopods.

This is my first fullbody art with shadows in digital, so I had to work hard before I found the way I needed to draw shadows. The result turned out to be quite good, so I will probably draw more often in this style. :) Based on this skeletal by Ashley Patch: www.deviantart.com/plastosplee…
Protofeathers were added in accordance with phylogenetic analyses showing megaraptorans as basal coelurosaurs or tyrannosauroids.

Thank you again for illustrating one of my favorite species! I really love how this turned out. The pose is very nice. You have an eye for doing nice poses that aren't just side views! Not that there's anything wrong with just profile views but I find them to be a bit boring at times and over-done in paleoart. Love the filaments and the way you have textured the skin. Do you imagine them to be mostly bare-skinned or to have extremely small scuta / reticulae scales on the majority of the body?
