During what era did theropods live?

Theropods first appear during the Carnian age of the Late Triassic about 220 million years ago ( mya) and were the sole large terrestrial carnivores from the Early Jurassic until the close of the Cretaceous, about 65 million years ago.

What did the theropods eat?

Theropod dinosaurs were meat-eaters (except for a very few that returned to eating plants) who walked on their two hind legs. Theropods ranged in size from relatively small, such as the Coelurosaur seen here, to the great Tyrannosaurs. Many theropods had feathers, and birds are their descendants.

Where do theropods live?

Theropod remains have been recovered from all continents except Antarctica and from the Middle Triassic through the Late Cretaceous Epoch (from 245 million to 65.5 million years ago).

Did all theropods have feathers?

Plumaceous feathers are found in nearly all lineages of Theropoda common in the northern hemisphere, and pennaceous feathers are attested as far down the tree as the Ornithomimosauria. The fact that only adult Ornithomimus had wing-like structures suggests that pennaceous feathers evolved for mating displays.

What environment did theropods live in?

Most of the dinosaurs we have found lived along ancient rivers or streams and roamed across the adjacent forested floodplains and densely vegetated swamps and lakes.

What's the spitting dinosaur in Jurassic Park?

The poison-spitting dinosaur reconstructed in Jurassic Park is Dilophosaurus. At the time the movie was produced, there was no evidence that this or any other dinosaur spat poison or had poisonous saliva of any kind.

Can theropods fly?

With this improved evolutionary tree, the team reconstructed the potential of bird-like theropods for powered flight, using proxies borrowed from the study flight in living birds. The team found that the potential for powered flight evolved at least three times in theropods: once in birds and twice in dromaeosaurids.

Do Archaeopteryx have longer arm bones?

Microraptor and Archaeopteryx, however, needed more elongated forelimbs to stay aloft, including upper arms longer than their shoulder blades. Additionally, Archaeopteryx's forearms, including its hands, were longer than its thighbones. Both of these traits are present in its modern bird descendants.

Is Rex a theropod?

The species Tyrannosaurus rex (rex meaning "king" in Latin), often called T. rex or colloquially T-Rex, is one of the best represented of these large theropods. ... Relative to its large and powerful hind limbs, the forelimbs of Tyrannosaurus were short but unusually powerful for their size, and they had two clawed digits.

Did theropods lay eggs?

But one group of dinosaurs with hard-shelled eggs, the theropods that later begat birds, had open-air nests they brooded—a much more involved form of parenting.

Can the Archaeopteryx fly?

Crow-sized Archaeopteryx, which lived about 150 million years ago in a tropical archipelago that is now Bavaria, combined primitive dinosaur characteristics with traits seen in modern birds. ... Its flight capabilities may have enabled Archaeopteryx to escape predators or fly among islands.

Do theropods have 3 digits?

Theropods, the predominantly carnivorous dinosaurs that included tyrannosaurids such as Tyrannosaurus rex and dromaeosaurids such as Velociraptor mongoliensis, also only had three long fingers.
