The Ediacaran seafloor shows a time before animals started burrowing through the sediment. The top layers were covered in thick microbial mats where these primitive animals lived. As time passed ...

It was named Ikaria wariootia. Until now, palaeontologists traced our ancestry to the explosion of marine lifeforms in the Cambrian period, which began 541 million years ago. It was thought that ...
