Sinorinthosaurus probably wasn't venemous. That hypothesis was based off of three things, elongated fangs, ridges in those fangs as a venom delivery system and a pocket in the skull said tonbe perfect for a venom gland. However upon examination by other scientists, this all proved to be false, the fangs were not elongated, they had just slid partially out of the socket, the ridge was far wider than what can be seen in modern animals with a venom delivery system of that type and really isn't any different that of other therapods, and finally there simply wasn't hollow structure as described by the initial study. As a very bird like dinosaur sinorinthosaurus had hollow bones, the "pocket" was hollow but so was the rest of the bone. There is no reason to assume that it help a venom gland. The "venomous dinosaur" simply isn't true and is merely the results of a scientist making grandiose claim either by accident or to boost his own reputation.
