There are several theories on how dinosaurs became extinct. The first and most common is the Asteroid Theory. Some believe they became extinct because of volcanic activity and others think it had something to do with the ice age. Others believe it could have been climate change or a new disease introduced to the dinosaurs that eventually killed them all off. All we know is that they are extinct and scientists still do not know…
First of all, dinosaurs are extinct. Approximatively 65 million years ago, the dinosaurs became extinct by what most people believe was a large meteorite which hit Earth and caused an Ice Age. Ash and dust covered the sun causing the Ice Age. Secondly, dinosaurs did not eat chocolate (chocolate was not in that time period) They ate other dinosaurs and plants depending on if they were carnivorous or herbivorous.
