In 1869, Dr. Ferdinand Vandeveer Hayden obtained a second hand fossil of an Allosaurus vertabrae that had come from Colorado. He sent it to Joseph Leidy, who in turn assigned it to the new genus Antrodemus. It is now known that this was an Allosaurus fossil. In 1877, Othniel Charles Marsh found some fragmentary remains of Allosaurus, which he then named Allosaurus fragilis.
I'l your end of days
Allosaurus is the most common meat eating dinosaur fossil in the areas where it lived. Sometimes an animal's lifestyle makes it disproportionately likely or unlikely to fossilize, but since Allosaurus is so common in the fossil record, they were probably relatively common when they existed.
The first Allosaurus was discovered in Colorado in 1869 during the Bone Wars, by Ferinand Hayden. Since then paleontologists have identified seven different species of the Allosaurus. In Utah, over 60 sets of remains have been found in one site, ranging from the eggs of an Allosaurus to full grown adults. The Allosaurus is also the state fossil of Utah. Fossils and remains of the Allosaurus have been found in Asia, Africa, Australia, and all over North America.
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.
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!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
There is no state dinosaur for Utah. The state fossil is Allosaurus. This is strange, though, because there are at least two dinosaurs named after Utah. They are Utahraptor and Utahceratops.
They could cooperate during hunting and also compete when carrion was found by them.
how many teeth does allosaurus have
"allosaurus" (different lizard)
