The Chinese scientific research team made the first-record finding in China on the latest archaeological research to the fossil in the Lower Permian (Cisuralian) period in Yangquan city, Shanxi Province. The discovery provided a proof that petalodus, a shark species with petal-shaped teeth, had migrated across the Paleo-Tethys Ocean in the history.

Characterized by petal-shaped teeth, the species is a top predator with excellent swimming ability in the ancient ocean.
