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.
This beach collected specimen has wonderful markings which are characteristic of this well known Cretaceous sponge. This is one of the finest examples of the species we have seen and will enhance any collection and would also make a great conversational piece to guess what it is !!!
