RE: Theropod Skin Impression

[Dino Guy Ralph <dinoguy@sbcglobal.net>]

There is a small patch of skin preserved on the foot of "Dave," the
_Sinornithosaurus_.  See Figure 4b:

There is a photo of a _Carnotaurus_ skin impression cast in Currie and
Padian's _Encyclopedia of Dinosaurs_, page 674, figure 11.  There is another
photo of a _Carnotaurus_ skin impression on page 19 in _Dinosaurs All
Around_ by Caroline Arnold.

Contact Stephen Czerkas.  He probably has dozens of high quality photos of
_Carnotaurus_ skin.
