Artistic restoration of Byronosaurus with secretary bird-like plumage. This timeline of troodontid research is a chronological listing of events in the history of paleontology focused on the troodontids, a group of bird-like theropod dinosaurs including animals like Troodon.
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.
Florida fossils are often very well preserved. [1] The oldest known fossils in Florida date back to the Eocene. At this time Florida was covered in a sea home to a variety of marine invertebrates and the primitive whales, such as Basilosaurus. During the later Miocene Florida was exposed as dry land again due to geologic uplift and mountain ...
All troodontids have many unique features of the skull, such as closely spaced teeth in the lower jaw, and large numbers of teeth. Troodontids have sickle-claws and raptorial hands, and some of the highest non-avian encephalization quotients, meaning they were behaviourally advanced and had keen senses. [15] Saurornithoides was a rather small ...
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).
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.
