In Sea Monsters: A Walking With Dinosaurs Trilogy, the shark camera shows the Megalodon hunting. Megalodon sees a giant whale (called Cetotherium) and goes into an attack pattern and bites for the tail of the Cetotherium, presumably successfully performing the typical rising attack and presumably leading to the death and consumption of the whale later.
