Troodon (/ˈtroʊ.ədɒn/ TROH-ə-don; Troödon in older sources) is a dubious genus of relatively small, bird-like dinosaurs known definitively from the Campanian age of the Cretaceous period (about 77 mya). It includes at least one species, Troodon formosus, known from Montana. Discovered in October 1855, T. formosus was among the first dinosaurs found in North America, although it was thought to be a lizard until 1877. Several well-known troodontid specimens from the Dinosaur Park Formation in Alberta were once believed to be members of this genus.
Though it has made many appearances in popular culture in the late 20th and early 21st century, analyses in 2017 have found the genus to be undiagnostic and referred some of these specimens to the genus Stenonychosaurus (long believed to be synonymous with Troodon) and others to the newly created genus Latenivenatrix.
Troodon are small feathered theropods. They have large orange eyes on narrow skulls with exposed upper teeth. They are mostly brown, although individuals may vary in shade. A lighter shade of brown exists on the snout, underbelly, and scales.
In Dinosaur PlanetEdit
Three Troodon are first seen unsuccessfully hunting a herd of Orodromeus. The hunt is ends early when a geyser shoots from the ground underneath one of the Troodon, killing it. Another pack is later seen drinking from a lake and missing the herd of Orodromeus hiding nearby. The pack from the beginning appears again during the volcanic eruption, with one being killed by a falling magma rock and the last one killed in a pyroclastic flow.
