Megalodon. Otodus megalodon (/ ˈmɛɡələdɒn / MEG-əl-ə-don; meaning "big tooth"), commonly known as megalodon, is an extinct species of giant mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Early Pliocene epochs.
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.
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 ...
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 ...
August 19. (2007-08-19) –. November 7, 2007. (2007-11-07) 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.
"The megalodon shark was the apex predator in the water," Bischoff said. Many other fish swam alongside these giant hunters. The bone beds also included an extinct saber-tooth salmon.
The extinct dire wolf (Aenocyon dirus) reached 1.5 m (4.9 ft) in length and weighed between 50 and 110 kg (110 and 243 lb). [42] [169] The largest wolf (Canis lupus) subspecies ever existed in Europe is the Canis lupus maximus from the Late Pleistocene of France.
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 ...
