39mm on 69mm chalk slab.

Conulus is an extinct genus of sea urchin known from the Early to Late Cretaceous (Valanginian to Maastrichtian) of Europe, Asia, and the Middle East.

This complete specimen on matrix makes a nice display piece. The smooth, dome-like shape on the irregular surface could appeal to those looking for forms of purely natural art.

Those who collect forams might want to take samples from the chalk matrix to see what they get.
