   Why is it that cool creatures like tyrannosaurs and supercrocs go extinct, and that we’re left with homo "sapiens", flies and cockroaches at the apex of the evolutionary tree ? 😛

   Apart from planetary level circumstances like climate change, one problem with those creatures is the size. The size of possible preys reduced, predators are forced to go the same way. The energy spent in hunting is not directly correlated to the size of the prey, and hence to the amount of energy obtained from it. For example, the size of sharks species is conditioned by the size of marine mammals or fish they can catch. The larger sharks will have a hard time at being efficient while moving all it’s mass hunting small animals.
   The carcharodon megalodon for example, was a shark like the one in the Jaws movie, but it’s extinct now. It’s diet consisted mostly of whales.
