Tochisaurus (meaning “Ostrich lizard”) is a genus of small troodontid theropod dinosaur from the Late Cretaceous Period of Mongolia. The type (and only named) species is Tochisaurus nemegtensis.

In 1948, a Soviet-Mongolian expedition found the remains of a small theropod in the Gobi Desert near Nemegt. In 1987 the find was reported by Sergei Kurzanov and later that year discussed by Halszka Osmólska who suggested it could represent a specimen of the troodontid Borogovia.

What we know

  • Named by Kurzanov and Osmólska, 1991.
  • Fossils found in Asia and Mongolia.

What we guess

The reconstruction notes for Tochisaurus — soft tissue, color, behavior — haven't been written up yet. Only the recorded basics above are filled in so far.
