is a genus
of megalosaurid dinosaur
from the Middle Jurassic
known largely from a fossilized braincase. The fossil is similar to Allosaurus
, but the braincase is larger, and the eye 'crests' are not as pronounced. It is estimated to be eleven metres (36 ft) long and weighed almost two tonnes.
The type species
is Piveteausaurus divesensis
, reclassified by Taquet and Welles in 1977. It was originally described as Eustreptospondylus divesensis
by Walker in 1964.
