CHENGJIANG, China, Jan. 18 (UPI) -- Scientists say examination of fossils in China has shed light on peculiar tentacled marine creatures that lived 520 million years ago.
It had been believed the creatures, Cotyledion tylodes, belonged to the cnidarian group of jellyfish-like animals, but anatomical features seen in the fossilized remains suggest the species was an early member of the group of small marine organisms called entoprocts, they said.
