Resumen de Mystery fossil may be a beast out of time
An odd 380-million-year-old fossil that looks like a worm might be the last known survivor of an early form of life. But some palaeontologists are sceptical. The Ediacarans were some of the earliest multicellular life forms. They were weird, bag-like organisms, a few millimetres thick and up to 2 metres long. Nobody knows if they were animals, plants or something else Ediacarans first appear in the fossil record about 600 million years ago. They are thought to have vanished 60 million years later, after animals burst onto the scene in the Cambrian period. They may all have beeneaten.
