Megalodon was the biggest predatory shark that have existed in Earth’s history. Latest studies say the pups of these sharks were larger than most humans when they’re born. This suggests that they hatched in the womb and were born live. Like modern sharks that give birth to live young, may have gobbled up their smaller siblings while still in the mother’s womb
Megalodon sharks lived from 23 million to around 3.6 million years ago, dominating the ocean. Palaeontologist have lots of evidence of Megalodon in the fossil record. Researchers calculated the size of megalodon babies by analysing skeletal fossils of an adult Otodus megalodon that measured about 30 feet (9 meters) long when it died. The scientists then looked at “growth rings” in pieces of the shark’s preserved skeleton, similar to the rings in tree trunks used to determine a tree’s age.
However, while teeth constitute the bulk of the Megalodon fossil record, some vertebrae have also been retrieved. And it was from several of these vertebrae, housed in the Royal Belgian Institute of Natural Sciences in Belgium, that scientists were able to learn more about the early lives of these mysterious animals.
The research was published in Historical Biology.
