Editing Allosaurus (section)

=== Skin ===
Skin impressions from ''Allosaurus'' have been described. One impression, from a juvenile specimen, measures 30&nbsp;cm² and is associated with the anterior dorsal ribs/pectoral region. The impression shows small [[Scale (anatomy)|scales]] measuring 1–3&nbsp;mm in diameter. A skin impression from the "Big Al Two" specimen, associated with the base of the tail, measures 20&nbsp;cm × 20&nbsp;cm and shows large scales measuring up to 2&nbsp;cm in diameter. However, it has been noted that these scales are more similar to those of [[Sauropoda|sauropods]], and due to the presence of non-theropod remains associated with the tail of "Big Al Two" there is a possibility that this skin impression is not from ''Allosaurus''.<ref name=":1">{{Cite journal |last1=Hendrickx |first1=Christophe |last2=Bell |first2=Phil R. |last3=Pittman |first3=Michael |last4=Milner |first4=Andrew R.

Another ''Allosaurus'' fossil features a skin impression from the [[mandible]], showing scales measuring 1–2&nbsp;mm in diameter. The same fossil also preserves skin measuring 20 × 20&nbsp;cm from the ventral side of the neck, showing scutate scales measuring 0.5&nbsp;cm wide and 11&nbsp;cm long. A small skin impression from an ''Allosaurus'' skull has been reported but never described.<ref name=":1"/>
