You are assertive of it, but you may be wrong. A new paper suggests that Sinornithosaurus a venomous dinosaur, based on its grooved teeth and hollows where venom glands could have sat. 

Sinornithosaurus (meaning “Chinese bird-lizard”) is a small feathered dromaeosaurid (or, more commonly, ‘raptor’) and an early distant cousin of the birds. Its teeth are unusually large and Gong says that those in the upper jaw are “so long and fang-like that the animal appears to be saber-toothed”. They’re very similar to the fangs of back-fanged snakes like boomslangs and vine snakes.
