23 – 2.58 million years ago
In this time lived the legendary Megalodon, or Megatooth shark lived. It was the most enormous shark that ever lived, and I am glad that it doesn’t live in the Holocene age (today). One of the Megalodon’s prey is Zygophyseter, a whale with teeth, about half the size of the 50-ton Megalodon (In my opinion, Zygophyseter looks like a beluga whale). I believe that the Megalodon, who’s scientific name is Otodus megalodon, is related to Otodus obliquus, a smaller extinct shark because of one reason…
They have the same Genus!
