Spriferina in ironstone.
The picture shows a Spiriferina fossil found
in the rock at Edgehill Quarry.

Spiriferina lived and fed in the sediment at the bottom of our Jurassic seas.

This one is still stuck there in the ironstone!

Ironstone was once the rusty red soil of our subtropical islands.

But tropical storms gradually washed the soil into the sea. The soil then became seabed sediment, and eventually rock.
