New species of Allosaurus discovered to be 5 million years older

Allosaurus jimmadseni is the oldest species of Allosaurus, roaming around Western North America from 157 million to 152 million years ago. The Allosaurus was 26 to 29 feet long and weighed up to 400 pounds, according to paleontologists.

It was uncovered in Dinosaur National Monument. Researchers say that it is the oldest meat-eating dinosaur found until now. Earlier, the paleontologists discovered only one species of Allosaurus, Allosaurus fragilis, in Jurassic North America. Now, recent studies proved that roaming around Western North America from 157 million to 152 million years ago. The studies also showed that they had different feeding behavior, and that  Allosaurus jimmadseni evolved at least 5 million years earlier than Allosaurus fragilis.

The term Allosaurus means “different reptile” and “jimmadseni” honors the Utah state paleontologist – James H. Madsen Jr. It is believed that one day, the dinosaurs faced an asteroid extinction event – nuclear strikes equal to the power of 10 million atomic bombs. This event is believed to have happened 66 million years ago.

As soon as the asteroid struck, it triggered large tsunami waves, wildfires, and released sulfur into the atmosphere, blocking out the sun and cooling down the earth’s atmosphere that commenced the beginning of the Ice Age. The remaining dinosaurs were later killed by the rapid cooling effect.
