Megalodon

.






The megalodon, Carcharodon or Carcharocles megalodon is an extinct megatoothed shark that existed in prehistoric times, from the Oligocene to Pleistocene epochs, approximately 25 to 1.5 million years ago.
C. megalodon may have been the largest and most powerful macro-predatory fish in vertebrate history. Fossil remains of C. megalodon indicate that it was the biggest shark that ever lived and possibly approached a maxima of around 20.3 metres (67 ft) in length. C. megalodon has been assigned to the order Lamniformes but its phylogeny is disputed. Scientists suggest that C. megalodon looked like a stockier version of the great white shark, Carcharodon carcharias, in life. Fossil evidence confirms that C. megalodon had a cosmopolitan distribution. C. megalodon was a super-predator, and bite marks on fossil bones of its victims indicate that it preyed upon large marine animals.
