This is a lovely and well preserved Scallop shell that is some 200 million years old. The scallop shell has been preserved on a block of Frodingham ironstone from the world famous and very sought after Scunthorpe quarries. Sadly, these quarries are no more, so items such as this will become scarse.
Collected over ten years ago this specimen was found in a temporary inland location. This is a classic Oxford Clay ammonite that has been preserved in pyrite and is totally matrix free. A lovely drawer specimen.
