LONDON.- Excellent eyesight is essential if you are a top predator, like the prehistoric sea creature Anomalocaris, an early arthropod relative that patrolled the oceans over 500 million years ago. However, finding proof that a long-extinct animal had super vision has been difficult, until now.

Its compound eyes had at least 16,000 lenses each, making its sight rival many arthropods living today. © Katrina Kenny A team of scientists led by University of New England, Australia, and including those at the Natural History Museum, have uncovered the first direct evidence that Anomalocaris had compound eyes, each with more than 16,000 lenses.
