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). It includes at least one species, Troodon formosus, known from Montana.
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.
It probably had good vision in light and very good night vision. It had a long, low head, a depressed muzzle, sharp teeth and a relatively large brain. Swift and smart, like its North American cousin Troodon, Saurornithoides probably scoured the Gobi Desert, looking for small mammals or reptiles to eat. Like other troodontids, it had an ...
Troodon bakkeri (Carpenter, 1982) Pectinodon is a genus of troodontid theropod dinosaurs from the end of the Maastrichtian age of the Late Cretaceous period (66 mya ). It currently contains a single valid species , Pectinodon bakkeri (sometimes classified as Troodon bakkeri ), known only from teeth.
The spawn (eggs) of a clownfish. The black spots are the developing eyes. Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and ...
In response to such findings, Purnell said preserved stomach contents are questionable because they do not necessarily represent the usual diet of the animal. The issue remains a subject of debate. [6] Coprolites (fossilized droppings) of some Late Cretaceous hadrosaurs show that the animals sometimes deliberately ate rotting wood.
A model of the hypothetical Dinosauroid, Dinosaur Museum, Dorchester. In 1982, Dale A. Russell, then curator of vertebrate fossils at the National Museum of Canada in Ottawa, conjectured a possible evolutionary path for Stenonychosaurus, if it had not perished in the Cretaceous–Paleogene extinction event, suggesting that it could have evolved into intelligent beings similar in body plan to ...
Troodon, Ozraptor, Tyrannosaurus rex, Troodon baby, Brachiosaurus, Corythosaurus: Trek gives the same dino field guide he and his brother Dan use to do to a girl named Dana and like the former two, the latter loves Dinosaurs and now she can see them and does experiments with them. 5.2: Dino Divers / A Game of Microraptor and Mouse: May 25, 2017 ...
