Conversely the increase in baleen whale size may have contributed to the extinction of megalodon, as they may have preferred to go after smaller whales; bite marks on large whale species may have come from scavenging sharks. Megalodon may have simply become coextinct with smaller whale species, such as Piscobalaena nana. [109]
During the Late Pleistocene, particularly from around 50,000 years ago onwards, most large mammal species became extinct, including 80% of all mammals greater than 1,000 kilograms (2,200 lb), while small animals were largely unaffected. This pronouncedly size-biased extinction is otherwise unprecedented in the geological record.
One of the most striking fossils around today are the teeth and reconstructed jaws of the megalodon.The jaws of the extinct shark are so big, one or two people can stand inside them. They're ...

A new study finds that megatooth sharks’ warm-blood adaptation and giant size may have played a role in their extinction. Scientists find new clue in what led to megalodon’s demise Skip to ...
The proportion of extinct large mammal species (more than or equal to 10 kg (22 lb)) in each country during the last 132,000 years, only counting extinctions earlier than 1000 years BP
The Pyrenean ibex, the only animal to have been brought back from extinction and the only one to go extinct twice. Main article: De-extinction Some, such as Harvard geneticist George M. Church , believe that ongoing technological advances will let us "bring back to life" an extinct species by cloning , using DNA from the remains of that species.
The second theory is basically the opposite: That fishing can drive a population to extinction. One of the study's authors said in a statement, "Bioeconomic thinking has predicted that scarcity ...
