Hmmm... Russell for "Tyrannosauridae", Currie for "Troodontidae"...BLAME CANADA! :-) :-)--On Sat, Aug 12, 2017 at 6:15 AM, Matt Martyniuk <martyniuk@gmail.com> wrote:Well, there was some question over whether or not Troodon was an ornithopod at one point. But what we now think of as "troodontids" were fairly well known, and known to be theropods. Saurornithoides, Stenonychosaurus, etc. It's just that they were called Saurornithoidids back then until Currie synonymized Stenonychosaurus with Troodon.
