Technosaurus is
based on TTUP P9021, which initially consisted of a
premaxilla (tip of the upper jaw), two lower jaw pieces, a back
vertebra, and an
astragalus.
Technosaurus and its
type species,
T. smalli, were named by
Sankar Chatterjee in 1984. He described it as a
fabrosaurid, a
clade of small, early ornithischians now considered to have been an artificial grouping. Material from the quarry where P9021 was found is disassociated and comes from a variety of Late Triassic animals, which would prove problematic. The genus was reviewed in 1991 by
Paul Sereno, who interpreted the premaxilla and a fragment from the front of the lower jaw as pertaining to a hatchling
prosauropod, and found the vertebra to be indeterminate and the astragalus an unidentifiable fragment. Thus, he restricted the remains to be considered
Technosaurus to the second lower jaw piece, a
posterior fragment. ==References==
