And the last of the Star Trek: Enterprise entries is a paleontological mention.
From Season 4, episode 19 "In a Mirror, Darkly, Part II", the crew is in the Mirror Universe and is being attacked by the infamous Gorn from the Original Series. While they are trying to figure out what did it they comment that they had "traces of reptilian saliva in the ... wounds" and the bite radius indicates a reptile that is more than 2 meters in length. When asked if this was a pet, the response was "Unless one of them owned a velociraptor, I find it extremely unlikely."
