‘Astonishing’ 500 million-year-old fossils preserved the brain of this creepy 3-eyed predator

An ocean predator from the Cambrian period known as Stanleycaris hirpex. Newfound fossils of the bizarre creature are exceptionally complete, preserving the brain, the nervous system and a third eye.

Researchers at the Royal Ontario Museum (ROM) in Toronto recently announced the discovery of fossils belonging to that strange animal as part of an “astonishing” treasure trove of fossils dating to 506 million years ago, according to a statement (opens in new tab).
