24 million-year-old nursery for baby megasharks discovered in South Carolina

About 24 million years ago, baby shark ancestors of the giant beast called megalodon needed a place to grow big before heading into the open ocean, so they swam around a coastal spot replete with easy-to-catch prey — a nursery in what is now South Carolina, according to new research.

Until now, scientists knew of just two fossil shark nurseries: a 10 million-year-old megalodon nursery in Panama and a 5 million-year great white shark nursery in Chile. In addition to being the third such nursery, the new discovery is also the first nursery on record for Carcharocles angustidens, a megatoothed shark that lived during the Oligocene epoch (34 million to 23 million years ago), said co-researcher Robert Boessenecker, a research fellow at the Mace Brown Museum of Natural History at the College of Charleston, in South Carolina.
