Jurassic period

I need to know how the JURASSIC period ended. (It'snot a metior hit Earth)

Jaz, everything you said is incorrect. The end of the Jurassic period has nothing to do with the end of the age of the dinosaurs or any other extinction event, for that matter. The dinosaurs were still very much alive when the Jurassic period came to a close.

The Jurassic is a measure of geologic time that runs from the end of the Triassic 200 million years ago to the beginning of the Cretaceous 145 million years ago. The beginning and end of the period are marked by specific ages of rock, not by what was living or dead. There are no competing theories about how it ended, and a meteor or climate change or a flood had nothing to do with it.

thats something that cant really be answered correctly, because there isnt an answer
just a lot of theories
one theory is that a meteor hit the earth and killed them all
another theory based on religion is that there was a flood that suposedly drowned them all
but one of the theories that seems a lot more accurate is that there was a change in temperature, causing many dinosaurs to die. and the ones that didnt die evolved to adapt to there surrounding and changing inviroment
