In Britain, found traces of the first jellyfish of the Earth.

In Charnwood Forest in Leicestershire, paleontologists have found body prints of the oldest jellyfish on Earth. She lived about 560 million years ago. This means that the first animals from this group appeared on the planet 20 million years earlier than is commonly believed. A. attenboroughii looks like a cross between a jellyfish and a coral. Her body is a standard goblet shape, but it is divided into several polyps. Scientists believe that A. attenboroughii was imprinted in the rock after it suffocated in sediment and ash flowing down the slope of an ancient underwater volcano.
