Allosaurus was a highly carnivorous dinosaur that was alive during the Jurassic period and inhabited Africa, Europe and North America. This has been confirmed as fossil of this carnivore has been found places like Utah, Colorado and Texas.
This dinosaur is possibly the second most famous carnosaur after the Tyrannosaurus Rex, This dinosaur was extremely powerful carnivorous theropod that lived during the late Jurassic Period. For many year this dinosaur was known as Antrodemus because that was how it was first categorised. Then later in 20th century this dinosaur got known as Allosaurus.
Allosaurus is commonly depicted in arts as being smaller than the Tyrannosaurus Rex and having slightly longer forelimbs and have three fingers instead of two. The largest specimen of this dinosaur reaches 32 feet in length.
The allosaurus has been existed from 163.5 million years ago and live in terrestrial habitat. This dinosaur reduced by laying eggs and had a body mass of about 2090kg and there has been 116 different specimens have been found by palaeontologist.
The Allosaurus would typically eat large herbivore dinosaurs such as Stegosaurus, they were known for being fast even for their size. They had razor sharp teeth. They lost teeth easily however they were continuously replaced, this is according to the 1976 analysis.
However in a study in 2001 studies shown that the Allosaurus had a bite that was weaker than lions, alligators and leopards. They is why people believe they used their large skull which has small horns above their eyes, which would do the most damage to its prey, and that they would use their teeth to rip the flesh of the dinosaurs.
The first fossil to be discovered was found in 1877 in Colorado and named by Othniel Charles Marsh. A more complete Allosaurus skeleton was found in 1879 by H.F. Hubbell, but it was left unpacked at the time.
