The report turned out to be erroneous. Unless there has been a new discovery of
_Herrerasaurus_ skin impressions or osteoderms, this was just a false lead.
And to update my e-mail allow me to say that the feathered compsognathid I refer
to is properly called _Sinosauropteryx prima_, and I have no doubt that it
sported simple feathers (which may or may not have exhibited a simple branching
pattern); _Pelicanimimus_ "skin" impressions were apparently subcutaneous muscle
tissue, which tells us nothing about its exterior appearance except that I
recall that the specimen apparently displays evidence for a dewlap under the
chin; and the hadrosaur skin impression from New Mexico were documented in the
article, "Dinosaur skin impressions and associated skeletal remains from the
Campanian of southwestern New Mexico: New data on the integument morphology of
hadrosaurs," by Anderson et al. in the Journal of Vertebrate Paleontology, 1998,
18(4): 739-745. See a _Discover_ brief at
<www.discover.com/may_99/images/Bump.jpg> for an image of the skin, which is
thought to be that of a gryposaur.
The most basal reliable theropod integument would seem to be that of
_Carnotaurus_, which is tubercular in nature, with a distinct rosette pattern.
See my post at <www.cmnh/dinoarch/1998Mar/msg00649.html> for references.
Sorry about _Herrerasaurus_, but it wasn't my fault! 8<#
