<dl><dd>•  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'. <sup id="cite_ref-BB98_1-0" class="reference"><a href="#cite_note-BB98-1">[1]</a></sup>  'Creosaurus' is genrally thought to be <a href="https://en.wikipedia.org/wiki/Synonym_(taxonomy)" class="extiw" title="en:Synonym (taxonomy)">synonymous</a> with <i>Allosaurus</i>. A study in 2015 using computer models came to a similar conclusion. <sup id="cite_ref-SLautenschlager2015_2-0" class="reference"><a href="#cite_note-SLautenschlager2015-2">[2]</a></sup></dd></dl><dl><dd>•  The skin details are partly speculative. A juvenille <a href="https://en.wikipedia.org/wiki/Allosauridae" class="extiw" title="en:Allosauridae">allosaur</a> is known to have had scaly skin on some parts of its body<sup id="cite_ref-JuvAllo98_3-0" class="reference"><a href="#cite_note-JuvAllo98-3">[3]</a></sup>.  Up until recently large theropods with skin impressions have shown 'typical dinosaurian' scales.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4">[4]</a></sup> In 2012 <i><a href="https://en.wikipedia.org/wiki/Yutyrannus" class="extiw" title="w:Yutyrannus">Yutyrannus</a></i> was described, it showed that large theropods could have been covered in feathers <sup id="cite_ref-yutyrannus_5-0" class="reference"><a href="#cite_note-yutyrannus-5">[5]</a></sup>. 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 <a href="https://en.wikipedia.org/wiki/Feathered_dinosaur" class="extiw" title="en:Feathered dinosaur">Feathered Dinosaur</a>).</dd></dl>
