Sea urchins, Claviaster beltremieuxi

Here we offer you three inconspicuous but quite rare sea urchins, Claviaster beltremieuxi.

The fossils come from the Cenomanian Inferior. This is the lowest stage of the Cenomanian,
a geological stage of the Upper Cretaceous that existed approximately 100.5 to 93.9 million years ago.

They were discovered in 1984 in Gémozac, a commune in western France in the
Charente-Maritime department in the Nouvelle-Aquitaine region.
