Description: Allosaurus skull: Showing the maximum possible gape of Allosaurus as hypothesized by Robert Bakker • The wide gape is based on figure 6 in 'Bakker 1998'. The head shape is based on specien AMNH 666, what Bakker calls 'Creosaur style allosaur'. [1] 'Creosaurus' is genrally thought to be synonymous with Allosaurus. A study in 2015 using computer models came to a similar conclusion. [2] • The skin details are partly speculative. A juvenille allosaur is known to have had scaly skin on some parts of its body[3]. Up until recently large theropods with skin impressions have shown 'typical dinosaurian' scales.[4] In 2012 Yutyrannus was described, it showed that large theropods could have been covered in feathers [5]. There are many dinosaurs being discovered from all over the family tree with evidence of quils or feathers so it is possible that allosaurs also had them (see Feathered Dinosaur).
