Still others needed date readjustments that took more recent analyses of those samples into account. Getting a more accurate read on the megalodon's demise is vital for understanding the forces driving the disappearance of these mega-beasts.

The new date, published February 12 in the journal PeerJ, coincides with the rise of the modern great white shark, hinting that this shakeup in the marine hierarchy may have spelled doom for the mighty âmeg.â. To solve the cold case, Boessenecker, now an adjunct lecturer at the College of Charleston, and his colleagues started searching for more traces of the megalodon in California, creating a compendium of West Coast finds. A great white shark compared with the much larger megalodon, and a hapless hypothetical human.

Past theories were often tied to a wider marine extinction that happened as the curtains closed on the Pliocene epoch roughly 2.6 million years ago. Pimiento went to several museums around the world and measured the tooth size of about 400 specimens of Megalodon. the above is true then Argentavis may have relied
For some mysterious reason, though the biggest and smallest members of the species were the same length, many of the giant sea monsters got longer over a 14-million-year period, and then, they all went extinct, new research suggests.. âNothing else is that cosmopolitan,â Boessenecker says.
