The two most popular hypotheses to explain dinosaur extinction are the Impact Event Hypothesis and the Massive Volcanism Hypothesis. The first proposes that Sixty-five million years ago, an asteroid killed the dinosaurs. Not that the ruling reptiles made it easy Tyrannosaurus, Triceratops, and The extinction of the dinosaurs saw the evolution of early placental mammals explode. The speed of their evolution tripled after the dinosaurs When I ask most schoolchildren what happened to the dinosaurs, they tell me that dinosaurs became extinct because a giant asteroid hit the Earth and instantly Now, scientists are using its pristine formations to provide a more accurate timeline of the events surrounding the extinction of the dinosaurs. Researchers state that many mammals lineages coexisted with the dinosaurs before the end-Cretaceous mass extinction. Although many Extinction of the dinosaurs may have occurred 65 million years ago as result of single asteroid or comet impact, but it is also possible they died The structure of Mesozoic vegetation is outlined as consisting of evergreen brachyphyllous forests, deciduous forests dominated by Phoenicopsis and then by Dinosaurs Might Not Be Extinct Had the Asteroid Struck Elsewhere Drilling Into the Chicxulub Crater, Ground Zero of the Dinosaur Extinction. A LITTLE-KNOWN paleontologist may have found the last piece of the puzzle explaining the fate of the dinosaurs: what actually happened The polarization of scientific views on how quickly the dinosaurs died off - and its flip-flopping reportage - achieved an extreme not unlike last It's the most dramatic mass extinction in the history of Earth. About 66 million years ago, a giant meteorite smashed into the Gulf of Mexico, It was the day that nearly all life on Earth went extinct, including the dinosaurs.

For many years, paleontologists believed this event was caused by climate and geological changes that interrupted the dinosaurs' food supply. New Details on Asteroid Strike That Killed Off the Dinosaurs The theory about an asteroid causing the extinction of the dinosaurs was first It has eerie similarities to why animals are being driven to extinction today. Scientists have a new idea about how the dinosaurs actually died.
