Unfortunately, I can't check my papers because they're buried in boxes right
now, but I think Rozhdestvensky is one person who interpreted this as an
actual species epithet and not an adjective, perhaps in the 1966 paper in
which he classified Sanpasaurus as a sauropod. In Tracy Ford's file I have
the following as the holotype of the species:
Holotype: IVPP V220
Locality: Locality 6, Kuantsaishan, near Houchiatsun, about 5 km NW of the

Horizon: Kuangyuan Series, Middle Jurassic.
Material: An anterior caudal vertebra, a distal end of a left femur, a left
tibia, a right fibula, and right foot with a few elements missing.
(Locality data are as for Sanpasaurus yaoi.) I dimly recall seeing Young's
original paper on this, and it looked to me as if he were creating a species
named Gen indet. imperfectus in it. Would have to see the paper again to be
