The dinosaurs in general haven't all died out. The genus of dinosaur "Aves" is still in existence. since birds are the descendants of dinosaurs. but most dinosaurs died out 65.5 million years ago at the KT boundary which is when the last major mass extinction occurred.

∙ 14y agoSome believe that they turned into birds, which doesn't make sense. How can an amphibian, a cold blooded animal, turn into a mammal, a warm blooded animal??
Many believe that it was a comet. I don't believe that because if that did happen, how are all the other reptiles and amphibians still alive? I can give you more evidence that it is not true but I don't want to write two pages at the moment.
In The Bible (Genesis 6) God (our creator) looks upon and saw us doing wicked things. He saw only one righteous, Noah. So God told Noah to build an Ark (big boat) and so he did. Now God led two of each animal (male and female) (seven of some animals for meat) and made them all fit in the ark. A great storm came and flooded the earth. Only Noah and his Family survived. After about a year, the ark settled Mount Ararat.
The flood destroyed many plants, leaving some of the dinosaurs to starve. some might've reproduced a few times before they died. Some might've even died before they were able to reproduce. Some might even be alive and just not discovered. I heard a rumor that they found some dinosaurs in a forbidden African jungle.
Many people wonder this but they are extinct; we can't bring them back :(
