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 !!!
This lovely specimen is complete and has good detail throughout. Wrens Nest is a world classic Silurian fossil locality which is approximately 410 million years old. A very good study fossil for the collector.
