Holectypus depressus

Specimens of Heliophora orbicularis, collected from the Western Sahara, Morocco. Heliophora orbicularis is an unusual species of echinoid, characterised by their unique finger like protrusions, jutting outward from one side. They date to the Upper Pilocene period, approximately 3.6 million years ago. They have a relatively flat, disc like shape and belong to the sand dollar family. Their distinct appearance is highly variable among individual specimens in terms of over all shape and size. These particular samples have been mostly cleaned and prepped so that features on the surface of the body can be viewed, as well as the ‘fingers’. Please note there may be some blemishes present however. These specimens are beige in colour and come supplied in a 1.5″ x 1.5″ white card try with information label.
