Fang Wound on 520‑Million‑Year‑Old Cambrian Predator Suggests Cannibalism

A fossil of a 520‑million‑year‑old apex predator from Cambrian seas shows a healed fang wound, indicating the animal once suffered a bite. The injury appears to have been inflicted by a similar creature, pointing to cannibalistic behavior among early marine predators. The find, preserved in exceptional detail, provides the first direct evidence that such large Cambrian predators may have preyed on their own kind. By revealing this aggressive interaction, the discovery offers a new perspective on the ecological dynamics of Cambrian ecosystems and the evolutionary pressures shaping early predator strategies.
