The Prehistoric Dark Lord of the Sith welcomes you, visitor.
Je m' intéresse à toutes les faunes de toutes les époques, périodes et ères, du Cambrien à nos jours. Le dessin est un de mes passe-temps mais de là à dire que je suis un artiste... hmm...
Oh, by the way, I'm the French Monster.

Daspletosaurus horneri, Tyrannosauridae and lips.As most of you know, in late March a new paper was published about a new species (it was known for a while, but unnamed) of Daspletosaurus, D.horneri. The authors suggested D. horneri had cracked keratin sheaths on the skull, as well as highly sensitive pressure sensors, which would make it lipless according to them.
The paper enacted huge ammounts of discussion, as both sides have made some good points. Here, I will give my own two cents on this sensitive topic, if you pardon the pun.
The writers of the paper, Carr et al. noted the similarity of the rugose bone texture and the well known bone texture on crocodilian crania.
Crocodillian's have a sensitive face covered in cracked keratin that leaves it's marks quite clearly on the skull, with a rough bone texture as a result: https://boneclones.com/images/store-product/product-1522-main-main-big-1416618898.jpg
While alive, these skulls look like this: http
