Pectinodon is a genus of dinosaurs from the Late Cretaceous period (66 mya). It currently contains a single species, Pectinodon bakkeri (sometimes classified as Troodon bakkeri), known mainly from teeth, as well as fragments of juvenile skeletons and eggshells. Pectionodon will be in the video game Saurian.
In 1982, Kenneth Carpenter named a number of theropod teeth from the late Maastrichtian Lance Formation of Wyoming as the type species Pectinodon bakkeri. The generic name is derived from Latin pecten, "comb", and Greek ὀδών, odon, "tooth", in reference to the comb-like serrations on the rear edge of the teeth. The specific name honors Robert Thomas Bakker.
The holotype, UCM 38445, consists of a 6.2 millimetres long tooth. The paratypes include other teeth and also a front dentary and a lower braincase. In 1985 Lev Nesov named a second species: Pectinodon asiamericanus based on specimen CCMGE 49/12176, a tooth from the Khodzhakul Formation of Uzbekistan, dating from the Cenomanian. This is today often considered a nomen dubium.
While historically considered synonymous with Troodon or more specifically the species Troodon formosus, Philip Currie and colleagues (1990) noted that the P. bakkeri fossils from the Hell Creek Formation and Lance Formation might belong to different species. In 1991, George Olshevsky assigned the Lance formation fossils to the species Troodon bakkeri. In 2011, Zanno and colleagues reviewed the convoluted history of troodontid classification in Late Cretaceous North America. They followed Longrich (2008) in treating Pectinodon bakkeri as a valid genus, and noted that it is likely the numerous Late Cretaceous specimens currently assigned to Troodon formosus almost certainly represent numerous new species, but that a more thorough review of the specimens is required.
In 2013 Currie and Derek Larson concluded that Pectinodon bakkeri was valid and its teeth could be found both in the Lance Formation and the coeval Hell Creek Formation. Some teeth from the older Campanian Dinosaur Park Formation could not be statistically differentiated from them, likely due to an insufficiently large sample, and were referred to a cf. Pectinodon.
In Saurian Edit
Pectinodon will be in Saurian. It is portrayed with feathers on pretty much all of the body, including wings on the forearms and a tail fan on the tail. Its' color is mainly black with white cheeks, reddish-brown tail, wings and snout, and sliver feet.
