Hi, my name is Kyle Bordes and I will be talking to you about how dinosaurs went extinct. So let's first talk about when this awful thing happened. It happened 65 million years ago. Normally when a group of dinosaurs died out it would be replaced with new ones but the devastation 65 million years ago was special.
So you guys have probably heard the reason dinosaurs became extinct. A giant asteroid came and hit Mexico. That's one theory but there are a couple more. The theory about that asteroid can be real but there are many more explanations. If an asteroid really hit the earth then some dinosaurs died, but not all of them. If only a few survived then they should have starved to death. If a couple of small asteroids were to scatter around the earth, the dinosaurs would starve because it would change the climate, and that would kill off all the plants. If all the plants were to be burn or die, that would kill the herbivores. If the herbivores died out than the carnivores would soon have to kill each other. Only a couple of dinosaurs are cannibals, like the carnotaurus, so then all of the dinosaurs would die out.
If there is that theory, than there are others. Many scientists think that disease killed the dinosaurs. They say that dinosaurs migrated to other lands because what else could they do, just sit around all day? After traveling they reach new lands. Sort of like Christopher Columbus, the diseases of the travelers killed the natives out and also killed the travelers. If this really happened, then why do we not have the viruses? Unless we do, I cannot believe this theory. Also, why would the dinosaurs move so far? So, like I said earlier, or more like a couple of seconds ago- I don't believe this.
The last theory I will talk about is that they are actually not extinct. AAAHH... oh no, so “scary”. No, they would be birds. That’s right, the tweety tweet things are relatives of our beloved Piatnitzkysaurus. For all of you who don't know what a Piatnitzkysaurus is then I have a picture.
This may be the most reasonable theory other than the asteroids. Did you know scientists are finding T-Rex DNA in my favorite animal...a chicken? So unless chickens were already chickens out there when dinosaurs ruled the earth, then I believe in the asteroid theory.
So that basically wraps everything up, but I have some cool dinosaurs I want to show you. The first one is called a Drinker Nisti. This is a small herbivore who would be normally picked on, and by picked on I mean picked out of a raptor’s teeth. Allosaurus was one of the most fierce dinosaurs because it would regrow its teeth like a shark.
Now, the last thing is the Triceratops. They were a herd of dinosaurs that were great moms because they would rather die than having their kids eaten. Now Trikes are my favorite dinosaur, I don’t know why, because they are just cool. Thank you for your time I hope you enjoyed.
