Where was the Allosaurus discovered?
Allosaurus, (genus Allosaurus), subsumes Antrodemus, large carnivorous dinosaurs that lived from 150 million to 144 million years ago during the Late Jurassic Period; they are best known from fossils found in the western United States, particularly from the Cleveland-Lloyd Quarry in Utah and the Garden Park Quarry in …
Was the Allosaurus a cannibal?
While there were hints of Allosaurus cannibalism in work done several decades ago, the new study presents “the strongest evidence so far” that these dinosaurs were eating one another, says Thomas R. Holtz, a paleontologist who studies carnivorous dinosaurs at the University of Maryland in College Park.
What dinosaurs had 500 teeth?
Nigersaurus
Bizarre 500-toothed dinosaur Nigersaurus, you might remember, we named for bones collected on the last expedition here three years ago. This sauropod (long-necked dinosaur) has an unusual skull containing as many as 500 slender teeth.
What is at Rex called?
Tyrannosaurus rex
Tyrannosaurus rex, whose name means “king of the tyrant lizards,” was built to rule. This dinosaur’s muscular body stretched as long as 40 feet—about the size of a school bus—from its snout to the tip of its powerful tail. Weighing up to eight tons, T. rex stomped headfirst across its territory on two strong legs.
Can dinosaurs be cannibals?
Cannibalism in dinosaurs is rare and has only previously been seen in the theropods T. rex and Majungasaurus, meaning this is the oldest recorded incident of dinosaurs munching one of their own.
Can animals be cannibals?
Cannibalism may be a major human taboo, but it’s surprisingly common in the animal kingdom. And there are a lot of good reasons to eat your own kind. The larvae of tiger salamanders can take two forms. The smaller type eats aquatic invertebrates, while the larger „cannibal morph“ feasts on its non-cannibal companions.

“A 6-ton T. rex,” Healy said, “would need the same daily calories as 80 people” on a diet of 2,500 calories per day. That translates to about 140 kilograms of meat, which the virtual T. rex had half a day to track down in the model.
Did some dinosaurs eat their babies?
His study, carried out with Oliver Rauhut of the Bavarian State Collection for Palaeontology and Geology in Munich, suggests baby-eating was a common behaviour among the large predatory dinosaurs, offering a possible explanation why so few juvenile dinosaurs have been found in fossil records.
