Large Clypeaster Sea Urchin
Very well defined
Base of the Sea Urchin
This is a large Clypeaster Sea Urchin, discovered in the Sahara of Egypt.
It dates from the Late Eocene, 35 million years old
The genus Clypeaster derives from the Latin, clypeus (meaning round shield) and aster (meaning star).
Echinoderms were the first animal to develop an internal skeleton, and were solitary marine organisms,
They fed, using their fine tentacles to direct food to their mouths, on micro marine organisms such as plankton.
Their first appearance was in the Cambrian Period, and their descendants still exist in the oceans of today of course.
This is an exceptionally large specimen, and well worth adding to a collection.
