There are several theories for why dinosaurs died out. One is that large meteors struck the earth, causing extensive damage and also causing the sky to be full of ash. While the sky was full of ash, there was no visible sun, so many plants died off, causing a chain-reaction in the food chain.

How many dinosaurs are there approx?
Technically Dinosaurs are extinct but there may be some evidence that a lizard might be a dinosaur.
How could plate tectonics have caused some species to become extinct?
Plate tectonics cause earthquake which may result into upheavals of earth perishing the living objects that become extinct in due course of time.
When will anchovies be extinct?
Impossible to say. They may never become extinct.
How is the Big Bang different from the asteroid that hit the Earth which may have caused dinosaurs to go extinct?
You are thinking of diffrent things. The big bang was a giant explosion that allowed all the dust and debris from that to come together to form earth. Billions of years later was the dinosaurs thing
Are Butterfly going extinct?
They may become extinct due to the lack of their habitats.
Why are butterfly going extinct?
They may become extinct due to the lack of their habitats.
Are you going to follow the dinosaurs?
Meaning "will people become extinct, as the dinosaurs did?" Well, yes, but extinction may not be what you think. A species can become extinct in one of two ways: by all members of its line dying off, and by evolving into another species. People weren't around at the time of the dinosaurs, by some creature who was our who-knows-how-many-times grandmother was. She was probably a little mouselike thing and her species is extinct, yet here we are. In another hundred million years, there won't be any people like us, so Homo sapiens sapiens (as we like to call ourselves) will be extinct; however, there might be some thriving creatures who don't look anything like us who will be our descendants.
Why did dinosaure finished to exist?
Dinosaurs existed because a group of archosaurs evolved to have legs directly underneath the body, a defining trait of the dinosaurs. They may have become so diverse because at the end of the Triassic, a mass extinction opened up many niches, and dinosaurs were able to evolve quickly enough to fill them. Modern birds later evolved from dinosaurs.
What may happen to a species whose limited habitat is destoryed by land development?
it will become extinct. NOVANET
Are mamouths dinosaurs?
NO. Mammoths were large mammals and lived millions of years after the dinosaurs became extinct. Dinosaurs do not fly (those are pterosaurs), dinosaurs do not swim (those are mosasaurs, plesiosaurs, etc. etc.) and dinosaurs became extinct approximately 65 million years ago, although the may have survived up to 62 million years ago. Mammoths only appeard a few million years ago, and they are related to elephants.
What was first extinct animal?
dinosaur...i think so.... No, animals were going extinct long before the dinosaurs. The earliest 'animals' were single-celled organisms, which may or may not have been named by scientists but are of little concern to mere mortals like ourselves. They would have been the ones to have first gone extinct on Earth, billions of years ago.
What causes extinctions?
Extinction is caused by a change in a species environment. The members of a species may not have adaptions that allow them to survive and reproduce in the changed environments. Extiction may also be caused by catastrophic upheavils that perish the entire living matter of that place and if an organism is localized to that region it may get ileminated.
