Holderness Sponges (erratics)

Hello All

We have found a few sponges on the Holderness that I would like the ID for.

Because of the nature of the Holderness being made up of several different boulder clays deposited during the last ice age all of these fossils were found loose on the beach (erratics).

These sponges probably came from the cretaceous chalk of the Flamborough area.

The first specimen is 4in high by 3in across with a hole in the center and was found by myself at Holmpton.
