Did an asteroid kill the dinosaurs?

It was an meteorite and climate change that killed the dinosaurs. Meteorites are similar to asteroids and are commonly called shooting stars. If an asteroid approaching towards the Earth catches fire due to the friction of the Earth's atmosphere, it is seen as a shooting star. The meteorite that killed the dinosaurs measured 6miles(10 km)

in length. It fell in the village of in Mexico. Due to the impact and the large mass of the meteorite, the sky was laden heavily with dust, particles which suffocated the dinosaurs.

Answer2: Listing some speculations as to what happened to them, Princeton scientist G. L. Jepson stated:

"Authors with varying competence have suggested that dinosaurs disappeared because the climate deteriorated . . . or that the diet did. . . . Other writers have put the blame on disease, parasites, . . . changes in the pressure or composition of the atmosphere, poison gases, volcanic dust, excessive oxygen from plants, meteorites, comets, gene pool drainage by little mammalian egg-eaters, . . . cosmic radiation, shift of Earth's rotational poles, floods, continental drift, . . . drainage of swamp and lake environments, sunspots."-The Riddle of the Dinosaur.

It is apparent from such speculation that scientists are not able, with any certainty, to answer the question: What happened to the dinosaurs?

University of Arizona scientist David Jablonski concludes that 'for many plants and animals, extinction was abrupt and somehow special.Mass extinctions are not merely the cumulative effects of gradual dyings. Something unusual happened.' Their arrival was also abrupt. Scientific American observes: "The sudden appearance of both suborders of the pterosaurs without any obvious antecedents is fairly typical of the fossil record." That is also the case with dinosaurs. Their relatively sudden appearance and disappearance contradicts the commonly accepted view of slow evolution.
