Animators have brought back some of the most fearsome ancient sea predators for a new interactive exhibit in Brighton, England.
The deadly Plesiosaurus, mighty Megalodon, and lethal Liopleurodon were some of the most fearsome creatures to roam the sea millions of years ago.
Now, a team have created realistic animations of them, which allow people to learn more about them, and even have a go at feeding them!
The exhibit also features prehistoric creatures which are still alive today, like terrapins and mudskippers, and has information about how help save endangered species.
