Allosaurus fossils have been found in the Morrison Formation of the western USA, the Tendaguru Formation of Tanzania, and the Lourinhã Formation of Portugal and date to between 155 and 150 million years ago. The two former areas, if not all three, were semi-arid, subtropical to tropical plains with distinct wet and dry seasons. Along rivers, there would have been forests of conifers, cycads, ginkgoes, ferns, and horsetails. Farther from the rivers there were open expanses, but rather than being covered in grass, which didn't exist yet, they were covered in ferns, and there were scattered trees. Allosaurus probably preferred the more open areas for hunting.

Allosaurus fossils are known from the Morrison Formation in western North America, the Lourinhã Formation in Portugal, and the Tendaguru Formation in Tanzania. These areas had a tropical to subtropical, semi-arid climate with distinct wet and dry seasons, and the land consisted of flat floodplains. Native plants would have included conifers, cycads, ferns, horsetails, and ginkgoes. Forests would have lined the waterways, while the areas farther from water would have been open fields of ferns with scattered trees.
Allosaurus was the largest predator in its habitat, so the only formidable enemy of an adult Allosaurus would be another adult Allosaurus. For young Allosaurus, however, threats included Torvosaurus and Ceratosaurus, and even larger Allosaurus.
Young Allosaurus were either protected by their parents or simply ran to escape danger. Adult Allosaurus were 28 feet long and weighed somewhere between 2,200 and 8,800 lb depending on whose estimate you use. Because they were the largest predators in their habitat, the only significant threat to adult Allosaurus were other adult Allosaurus. They would have fought each other mostly by biting, but they may have also used their relatively strong arms and struck each other with their claws.

There is one accepted species in the Allosaurus genus. Its full Latin (or scientific) name is Allosaurus fragilis.
Allosaurus did not have horns.
allosaurus is hungry!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
how many teeth does allosaurus have
"allosaurus" (different lizard)
There were many species of allosaurs. Allosaurus Fragilis, Allosaurus Atrox, and Allosaurus Amplexus, plus others. Some were nearly as large as T Rex.
No descendants of Allosaurus exist today. However, birds evolved from other carnivorous dinosaurs, which were relatives of Allosaurus. Thus, the closest living relatives of Allosaurus are birds. All birds are equally related to Allosaurus.
No, allosaurus was the top predatore of its age.
Allosaurus means "Different Lizard".
