A spectacularly well-preserved sea monster that once prowled the oceans during the Cambrian Period has been unearthed in China.
The 520-million-year-old creature, one of the first predators of its day, sported compound eyes, body armor and two spiky claws for grabbing prey.
The fossils of the new species were so well preserved that the nervous system and parts of the brain were still clearly defined.
