Moss Animals

A group of prehistoric "moss animals" called Bryozoa - tentacled animals that lived in massive colonies - are not as ancient as previously thought; the earliest fossils of these creatures are seaweeds, a new study found.
In the peer-reviewed study, which was supported by China's National Natural Science Foundation and published on Wednesday in the journal Nature, researchers at Durham University in the United Kingdom and Yunnan University and Guizhou University in China found that the fossils - previously believed to be the oldest Bryozoans - are actually green algae.
This means that Bryozoans are millions of years younger than previously thought.
Bryozoans lived during the Cambrian "explosion," a period of quick evolution 440 million years ago, 40 million years earlier than they were thought to have lived.
