Summary

Description
العربية: جُمجُمة ألوصور: رسمٌ يُظهرُ أقصى حد لِفتحة فم الألوصور كما افترض روبرت باكر
English: 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).

Note: I often update my images; If you want to post this image on other websites, if possible, please link to the original file here. This will allow others to see the most recent version. Thanks.
