A meteorite impact
The pterandon was a flying reptile and not a dinosaur as many people believe. It is believed that they died out and became extinct due to a direct meteor hit to the Earth.
because they could not survive the cool climate
a giant asteroid hit them
No, because dinosaurs (ALL of them) died out millions of years ago and officially became extinct.
dinosaur
Non avian dinosaurs became extinct 65.5 million years ago, at the end of the Cretaceous. However, birds are considered dinosaurs. Because birds still exist, dinosaurs are not completely extinct.
because have you seen any dinosaurs around? and go dig everywhere you will eventuly find dinosaur bones.
they are believed to have become extinct around 65 million years ago...... the reason they became extinct is that a huge meteor hit the earth and wiped the whole dinosaur-related population out .... just aswell this happened otherwise it is unlikely we would exist now....
