Description

New work and experiment. Several times I met examples of pencil drawings on a black background and decided to try my own. This is a portrait of Tyrannosaurus rex. The depicted individual was not based directly on any known specimen, although the shape of the nose resembles Stan, my favorite T. rex.

In this portrait I have focused my current wiews on the facial integument of a Tyrannosaurus rex. The figure shows rough, keratinized skin and exposed teeth. However, my version is different from Carr et al, 2017. In addition to the cracked keratin of "crocodilian" type with mechanoreceptors along a maxillary teeth row, there are maxillary structures that have left depressions in this bone in some tyrannosaurids (more details can be found in this video WitmerLab: www.youtube.com/watch?v=xTsVzx… , as well as in the corresponding article on the blog of Mark Witton). Top of the muzzle shows a keratinized skin, particularly on nose. The lower jaw Integument, however, is slightly different. The covers around the eyes is more "traditional". For those who this view seems inconsistent with reality: this is just my opinion, I could be wrong.

As for the other parts, I can mention the pronounced jaw muscles responsible for the bone-crushing bite. The neck is covered with wrinkled skin with a very small "reticulae", which does not deserve the drawing.

Technical HB pencil, black watercolor and black marker, 2019.
