Troodontidae / t r oʊ. ə ˈ d ɒ n t ɪ d iː / is a clade of bird-like theropod dinosaurs from the Late Jurassic to Late Cretaceous.During most of the 20th century, troodontid fossils were few and incomplete and they have therefore been allied, at various times, with many dinosaurian lineages.
Since these families were the same but the Troodontidae named first, it carries scientific legitimacy. [2] Many milestones of troodontid research occurred between the description of Troodon and the resolution of their confusion with pachycephalosaurs. The family itself was named by Charles Whitney Gilmore in 1924. [2]
Troodon (/ ˈ t r oʊ. ə d ɒ n / TROH-ə-don; Troödon in older sources) is a former wastebasket taxon and a potentially dubious genus of relatively small, bird-like theropod dinosaurs definitively known from the Campanian age of the Late Cretaceous period (about 77 mya).
The specific name honors television paleontologist Dr. Scott D. Sampson for researching and collecting fossils during ... In 2011 Talos was assigned to the Troodontidae.
While Pectinodon is only known from teeth, its larger family Troodontidae is known from much more complete specimens. They were small, bird-like feathered bipedal maniraptorans with proportionally large eyes and brains. Like dromaeosaurids, they possessed a "sickle-claw" on the second toe of each foot. See the Troodontidae article for more ...
Latenivenatrix, meaning "hiding huntress", is a genus of large troodontid known from a single species, L. mcmasterae.Along with the contemporary Stenonychosaurus, it is known from non-tooth fossils that were formerly assigned to the now potentially dubious genus Troodon.
Saurornithoides (/ s ɔː ˌ r ɔːr n ɪ ˈ θ ɔɪ d iː z / saw-ROR-ni-THOY-deez) is a genus of troodontid maniraptoran dinosaur, which lived during the Late Cretaceous period.These creatures were predators, which could run fast on their hind legs and had excellent sight and hearing.
Its holotype fossil, PIN 551-224, was found in a layer of the Nemegt Formation, dating from the early Maastrichtian, about 69 million years old. It consists solely of the (left) metatarsus, the first discovered of an Asian troodontid. The first metatarsal is missing. The top of the fossil shows some damage that was originally somewhat ...
