Fw: Allosaur skin
I apologize for the repetition, here, but my previous post omitted the URL,
so here we go again...
Now that I have the URL for the 2003 SVP Abstract Volume,
which is http://www.vertpaleo.org/meetings/VRPA2303supp_all.pdf,
I can refer interested parties to the abstract by Pinegar et al., "A
juvenile allosaur with preserved integument from the basal Morrison
Formation of central Wyoming," on pp. 87A/87B. Please note that if you
wish to print this page out you will need to specify pp. 89-90 during
Quoting the abstract:
"The left side of the body preserves a 30 cm squared skin impression
consisting of small scales 2-3 mm in diameter. This suggests that
juvenile allosaurs possessed scaly integument. This represents the most
derived tetanuran to retain this character, otherwise present in more
basal theropods such as _Carnotaurus_."
Actually, given a length estimate of 4 meters for the allosaur,
_Allosaurus sp._, 30 sq. cm. isn't all that much skin.
