LARGE SEA URCHINS ECHINOIDS
Large Sea Urchins Echinoids undescribed Monostychia with oyster plate attachments adhering. This is quite an attractive piece, great for a collector of Australian Sea Fossils. A real bargain too.
Sea Urchins are a group of marine invertebrates that today can be found in almost every major marine habitat from the poles to the equator and from the intertidal zone to depths of more than 5,000 metres. There are around 800 extant species and the group has a long and detailed fossil record stretching back about 450 million years ago.
