A group of researchers have found a tiny shrimp-like fossil, which is thought to be around 430 million-years-old.
The creature was preserved in ancient volcanic rock. The researchers decided to name it after their favourite naturalist Sir David Attenborough.
The creature has been named as Cascolus Ravitis, which is a combination of the Latin word for Attenborough, and the Roman word for Leicester, where the naturalist lived.
