The last dinosaurs on earth


Triceratops is estimated to be last a non birds dinosaur on Earth. This conclusion was drawn after the research scientists of fossils from Hell Creek Formation, Montana, United States designated. Triceratops is the youngest dinosaur ever discovered. The findings are very close to the disaster Triceratops meteor 65 million years ago also tend to refute the theory that the extinction of the dinosaurs took place gradually.

"Our study really shows that the extinction caused by meteor impact," said study leader Tyler Lyson told Discovery News. Meteor impact in the Yucatan Peninsula, Mexico, destroying most of the dinosaurs, especially the dinosaurs that can not fly.

By studying the geological layers in the area, Lyson and his team discovered that the dinosaurs suddenly disappeared after a super disaster.

Meanwhile, the theory of gradual extinction of dinosaurs based on the gap as thick as 3 meters in the geological zone where the dinosaur fossils found before the disaster.

Triceratops was found in Hell Creek above the zone of 3 meters. "This shows there is one species, or even more, which is still alive when a disaster occurs," said one researcher. According to Stephen Chester, one of the researchers are also involved in the study, the location of important discoveries. "In addition to dinosaurs, we also found a diversity of small mammals was first documented after disasters Mammals undergo adaptation. And begin to fill the empty land," the researchers said.

Until now, scientists have not been able to find a good reason to explain how mammals, turtles, and a few other animals could have survived the meteor disaster
