Everybody knows at least one gastropod - the common garden snail.
Besides garden snails, other gastropods include slugs, sea slugs and marine snails like limpets and periwinkles.
Gastropods live in many different environments, on land, in the sea, and in fresh water pools or streams. They use their broad flat foot for crawling, swimming or burrowing.
Many gastropods are protected in a cap-shaped or coiled shell. It is these shells that are often found as fossils. The oldest gastropod fossils are over 500 million years old.
Fossil gastropods come in all shapes and sizes.
The molluscs are split into different groups - the gastropods, bivalves and cephalopods. The cephalopods are also split into three groups.
