Earliest animal fossils are identified


Scientists have identified the earliest known animal in the geological record.

It's a 558-million-year-old oval-shaped creature that may have borne a superficial resemblance to a segmented jellyfish.

Researchers found specimens of the creature, known as Dickinsonia, that was so well preserved they still contained molecules of cholesterol.
