Question

What was reasons for how dinosaurs die

Answer 1

Explanation:

Dinosaurs are a diverse group of reptiles[note 1] of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago,[1][2] although the exact origin and timing of the evolution of dinosaurs is the subject of active research.[3] They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago; their dominance continued through the Jurassic and Cretaceous periods. Reverse genetic engineering[4] and the fossil record both demonstrate that birds are modern feathered dinosaurs,[5] having evolved from earlier theropods during the late Jurassic Period.[6] As such, birds were the only dinosaur lineage to survive the Cretaceous–Paleogene extinction event 66 million years ago.[7] Dinosaurs can therefore be divided into avian dinosaurs, or birds; and non-avian dinosaurs, which are all dinosaurs other than birds. This article deals primarily with non-avian dinosaurs.

Here is your answer ......

The great reason of death of all the Dinosaur is that one around 66 million years ago , A huge asteroid

clashed with earth. This cause the dinosaur of that area where asteroid had clash to crush . When the asteroid clashed some of it got raised in space and some times it stated to fallen down as a volcanic ball. The climate of Earth became so hot with high volume of sulphuric contents in air. This was cause the problem that the Dinosaur became unable to took oxygen from air and hence all the animals died . But some mammals are usually live underground and hence they only got survived on the earth and later that mammals developed day to day and becomes several hundred species including our predators Homosapiens .
