Troodon (/’troU.@danor TROH-@-don in earlier source) is a wastebasket taxon, and is a unreliable genus comprising tiny, bird-like dinosaurs recognized as being from the Campanian time period in the Late Cretaceous period (about 77 mya). It contains at most an individual species called Troodon formosus which is found in Montana. It was discovered in the month of October 1855. T. formosus was one of the first dinosaurs to be discovered within North America, although it was believed as a lizard up to 1877. A number of well-known troodontids of the Dinosaur Park Formation in Alberta were previously believed to be part of this Genus. But, new analyses conducted in 2017 have revealed the genus not to be diagnostic and have linked some of these specimens to the Genus Stenonychosaurus (long thought to be the same as the troodontid) while others belong to the Latenivenatrix genus.

The genus ‘ name is Greek meaning “wounding tooth”, referring to the teeth which were distinct from those of theropods that were known when they were first discovered. The teeth are prominent and have serrations with an apically-oriented orientation. The “wounding” serrations, however they are morphometrically closer to those of reptiles with herbivorous diets and could indicate an food source that is omnivorous.
