Distinctive Features of Allosaurus

Over 40 fossils of Allosaurus have been unearthed, shedding light on this formidable predator whose name means 'different lizard' or 'strange lizard.' It was one of the largest and most powerful carnivorous dinosaurs of the Jurassic period. Known for its large head and jaws, this predator had about 30 sharp teeth on both its upper and lower jaws.

Unlike some other theropods, Allosaurus typically hunted alone, rather than in packs. Its prey included massive herbivorous dinosaurs, such as Apatosaurus, and even other carnivores. Evidence of its predatory habits includes fossilized bite marks on Apatosaurus bones, as well as broken Allosaurus teeth found nearby, suggesting fierce confrontations.

Hunting and Physical Characteristics

In addition to actively hunting, Allosaurus was likely a scavenger, consuming the carcasses of dead animals when available. A notable feature of the Allosaurus was a bony ridge above each eye, likely serving as protection. Its forelimbs were equipped with three-fingered hands, each ending in sharp claws, while its powerful hind limbs had four-toed feet designed for speed. Its long, muscular tail helped maintain balance while running, making this dinosaur a swift and agile predator despite its large size.
