The greatest shark to ever swim the oceans had big, sharp, serrated teeth that it might utilize to tear into its victim like a handful of knives.
However nature didn’t simply hand these instant-killing weapons to these ancient sharks, called megalodons Rather, it took countless years for the teeth to develop into their last, deadly type, according to a brand-new research study released on March 1 in the Journal of Vertebrate Paleontology
To comprehend the advancement of megalodon’s killer teeth, scientists at the Florida Museum of Nature performed some ancient oral evaluations. They examined 359 fossils of teeth discovered– mainly by amateur fossil collectors– on the Calvert Cliffs, which lie on the coast of the Chesapeake Bay in Maryland.

About 20 million to 7.6 million years earlier, this location became part of the ocean, according to a declaration from the museum. And now, these dry hills hold ratings of fossilized teeth from the 2 enormous sharks that swam through the water throughout that time duration: megalodon and its most instant forefather, a shark called Carcharocles chubutensis
Previous research study has actually revealed that megalodon’s earliest forefather, called Otodus obliquus, which lived in between 60 million to 40 million years earlier, had smooth teeth with “cusplets,” or tiny teeth, that surrounded either sides of the primary tooth. These three-pronged teeth might have been utilized like a fork for grasping and tearing into victim, according to the declaration.
