- Allosaurus Used to Be Known as Antrodemus. Like many early dinosaur discoveries, Allosaurus bounced around a bit in the classification bins after its "type fossil" was excavated in the American West, in the late 19th century.
- Allosaurus Liked to Lunch on Stegosaurus. Paleontologists have unearthed solid evidence that Allosaurus preyed on (or at least occasionally tussled with) Stegosaurus: an Allosaurus vertebra with a puncture wound that matches the size and shape of a Stegosaurus tail spike (or "thagomizer"), and a Stegosaurus neck bone bearing an Allosaurus-shaped bite mark.
- Allosaurus Was Constantly Shedding and Replacing Its Teeth. Like many predatory dinosaurs of the Mesozoic Era (not to mention modern crocodiles), Allosaurus constantly grew, shed and replaced its teeth, some of which averaged three or four inches in length.
- The Typical Allosaurus Lived for About 25 Years. Estimating the life span of any given dinosaur is always a tricky matter, but based on the voluminous fossil evidence, paleontologists believe Allosaurus attained its full adult size by the age of 15 or so, at which point it was no longer vulnerable to predation by other large theropods or other hungry Allosaurus adults.

Allosaurus feasted mostly on large herbivore dinosaurs, and paleontologists have long thought the dinosaur tussled with Stegosaurus. In 1914, paleontologist C. W. Gilmore described three Stegosaurustail spikes that broke or became malformed during the dinosaur's life, suggesting it whacked other dinosaurs hard enough to break its spikes, Mossbrucke...
The first Allosaurus was discovered in 1877 in Colorado and named by Othniel Charles Marsh. This specimen offered just a few fragments of the dinosaur. Marsh went on to name other, seemingly unique dinosaur specimens, which, with time, were discovered to also be Allosaurusfossils, causing quite a bit of confusion in the early documentation of this ...

Allosaurus is a large carnivorous dinosaur that lived approximately 155 to 150 million years ago. Like many other predatory dinosaurs, Allosaurus walked on two legs, and had long, sharp teeth. They were formidable predators, and massive dinosaurs.
The Allosaurus (/,ael@’so:r@s) is the genus belonging to the huge carnosaurian theropod dinosaurs, which lived from 155-145 million years in the Late Jurassic epoch (Kimmeridgian to late Tithonian). It was first discovered in 1877 by Othniel Charles Marsh and was a massive bipedal predator.
The Allosaurus was a giant carnivorous dinosaur that roamed the Earth during the late Jurassic period, about 155 to 150 million years ago. Known for its large skull, powerful jaws, and serrated teeth, this fearsome predator was one of the top carnivores of its time.
