If you are talking about the dinosaurs. Two reasons: First there was a huge volcanic eruptions happening in India. This made the world hotter. Second was a huge asteriod that hit the earth about 65 million years ago.
Did the dinosaurs extinct at once?
No, not all at once. Throughout the 150 million year "reign" of the dinosaurs, all kinds of groups of dinosaurs have flourished then died out. Dinosaurs living in the Triassic Period were not the same as dinosaurs living in the Cretaceous period. However, the final blow to the dinosaurs that caused them all to die out was the K-T mass extinction that occurred 65 million years ago.

Evidence leads most paleontologists to believe the Devonian mass extinction event to be caused by global cooling, triggered by a glaciation event on Godwana. A less-proven theory states the extinction could have also been caused by meteoric impact.Background Info:After the Ordovician mass extinction event around 440 - 450 million years ago, surviving groups of species continued to diversify evolutionarily into what became the Silurian and Devonian periods.The Devonian period spanned from 408-360 million years ago, in which came the first sharks, bony fish, and ammonoids (a type of predatory mollusk) in the ocean, as well as terrestrial amphibians, insects, and true land plants.
