A tiny shrimp-like fossil which is thought to be around 430 million-years-old has been discovered.
Researchers found the creature preserved in ancient volcanic rock, and decided to name it after Sir David Attenborough.
They called it: Cascolus Ravitis, which is a combination of the Latin word for Attenborough, and the Roman word for Leicester, where Sir David lived.
The newly discovered creature is a tiny arthropod – a group of animals which includes things like spiders, shrimp, and crayfish, who have their skeletons on the outside of their bodies, like shells.
Sir David Attenborough is the voice behind many wildlife documentaries. His marvellous TV career has introduced generations to the wonders of the natural world for more than 60 years.
