It's well established that a major asteroid collision 66 million years ago in the present Gulf of Mexico caused an extended global winter which led to the extinction of 75% of species worldwide, including the dinosaurs, insects and animals on land and in the sea over the following 30,000 years. This also created an evolutionary advantage for warm-blooded mammals.
