Mammals Weren’t the Only Life Boosted by the Death of the Dinosaurs

June 30th, 2015

The death of the dinosaurs was good news for mammals. Those furry little guys who were scurrying around trying not to be stepped on or eaten by dinosaurs must have had a rough time just trying to survive. They would not have had much of any chance of actually establishing themselves in any position of dominance anywhere near the top of the food chain as long as dinosaurs walked the earth. Especially in light of a hit movie in theaters now, many of us wonder at the thought of dinosaurs still being alive. We, however, probably owe our existence to an asteroid coming along and wiping them out so those little mammals could crawl out from their holes and eventually become us.

Mammals, it seems, were not the only beneficiaries of the mass extinction that occurred about 65 million years ago. A recent find indicates that fish diversity shot way up after this time as well. It is mainly believed that the extinction of ammonites, or a type of marine invertebrate animal, was the basis for the population and diversity of fish taking off. People at Boraie Development (linkedin) know that it is believed that ammonites and fish would have competed for the same food resources in the world’s oceans. Being extinct, we’ve never had occasion to eat an ammonite, but I can’t imagine it tasted as good as tuna or salmon, so this development was an eventual win for us mammals as well.
