What are two pieces of evidence used two support the theory that dinosaurs became extinct as a result of volcanic eruptions about 65 million years ago?
Using fossils and geographical clues, paleontologists have determined with some certainty that a meteor, not a volcano killed the dinosaurs. Although dinosaurs died out, some birds survived and today's birds are the direct descendants of the dinosaurs.
