Weird, Extinct Animal Species Identified in First Such Finding in Over 100 Years

Peering back hundreds of millions of years into the past can turn up some astonishing findings – as it has with the discovery of a second species of opabiniid, a soft-bodied arthropod with a segmented exoskeleton that lived on the seafloor during the Miaolingian (509-497 million years ago). The original opadiniid, Opabinia regalis, was first described over a century ago in 1912, and has several notable physical characteristics – not least the five eyes protruding on stalks from its head, a backwards-facing mouth, and its hollow, tubular proboscis. Now there's another: Opabinia regalis is not as unique a species as first thought, because it's been joined by Utaurora comosa. This creature was previously thought to belong to a different group of animals known as radiodonts, but has now been reclassified as an opabiniid after some extensive research.
