  You’d have to ask a paleontologist for a more accurate answer, but I believe the consensus is now that a huge meteorite hit near Mexico caused devastating changes to the climate for several years which made food scarce. Apparently, dinosaurs were already dying out so the meteorite might have only accelerated their demise.
