The extinction of megalodon set the stage for further changes in marine communities. The average body size of baleen whales increased significantly after its disappearance, although possibly due to other, climate-related, causes. [119] Conversely the increase in baleen whale size may have contributed to the extinction of megalodon, as they may ...
The extinction was biased toward larger-sized species because smaller species have greater resilience because of their life history traits (e.g., shorter gestation time, greater population sizes, etc.). Humans are thought to be the cause because other earlier immigrations of mammals into North America from Eurasia did not cause extinctions. [212]
This idea is no longer considered valid, as improved dating on Titanis specimens show that the last phorusrhacids went extinct over one million years before humans arrived. [9] However, several fossil finds of smaller forms have been described from the late Pleistocene of Uruguay in South America.

Marine mammals likely constituted a big part of megalodon's menu, so with it gone, they were free to thrive. Observations indicate that in the years since the mega-shark's extinction, baleen ...
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 ...
Prehistoric Predators is a 2007 National Geographic Channel program based on different predators that lived in the Cenozoic era, including Smilodon and C. megalodon.The series investigated how such beasts hunted and fought other creatures, and what drove them to extinction.
A giant shark that was known as a megalodon use to terrorize the underwater world. Although the enormous sharks didn't make the evolutionary cut, researchers believe they still had a big impact on ...
