Theropod soft tissue
Nobody seems to have copped to the following article, in the latest issue of
Kellner, A. W. A., 1996. "Fossilized theropod soft tissue," _Nature
379_(6560): 32 [January 4, 1996].
There are SEM photos of a smallish ?maniraptoran specimen found in a
calcareous concretion from the Santana Formation (which produces all those
nice pterosaurs). Sorry, no feathers, scales, or ossicles--and they would
have been preserved had they been present. The material includes a pelvis,
hind limbs, and some caudal vertebrae in addition to the soft tissue. Blood
vessels, muscle fibers, other good stuff.
