Why did the megalodon go extinct while the shark which was much smaller and less fierce survive?

Hi Tegan,

My expertise is in physical oceanography, not marine biology or paleontology, so I'm sorry I cannot provide an authoritative answer to your question.

Nonetheless, I suggest you Google megalodon to see if they went extinct near the same time as the dinosaurs, in which case the reasons for their demise might also apply to the megalodon. Also, are megalodons and sharks from the same 'family' (biological classification)? If not, then survival and extinction pressures for the two types of animals may not be closely linked.

Good luck.
