1.1" Ordovician Carpoid Fossil - Ktaoua Formation, Morocco

This is a 1.1" long Ordovician aged carpoid fossils from the Ktaoua Formation of Morocco. The orange coloration is due to the oxidization of iron pyrite.

Carpoids are bizarre and somewhat controversial invertebrates - they are extinct, early echinoderms (living examples are starfish, sea urchins and sea lilies). Carpoids first appeared in the fossil record in the Cambrian Period with some types surviving into the Carboniferous Period.

They are an enigma to scientists and much has yet to be learned as to exactly how these creatures lived. Because they are so unlike other echinoderms, carpoids are now placed within the subphylum, Homalazoa. This is due to the fact they lack radial symmetry and an obvious hydrovascular system. However, like echinoderms, carpoids possess a calcite skeleton made up of plates in a three-dimensional mesh called a stereom.
