Peru Uncovers Near-Complete 7-Meter Shark Ancestor Pointing to Great White Origins
Peru’s Pisco Basin has yielded a nearly complete 9-million-year-old fossil of Cosmopolitodus hastalis, a seven-meter-long relative of the modern great white, with 9-centimeter blade-like teeth and sardine remains in its stomach. The well-preserved specimen offers rare insight into jaw arrangement and tooth evolution, supporting a transitional path from mako-like sharks to modern great whites.
