1.5" Ordovician Crinoid & Carpoid Fossil - Kaid Rami, Morocco

This is a nicely preserved Ordovician aged crinoid fossil from the Kataoua formation of Morocco. It's 1.5" long, nicely detailed and centered on a 3.2x1.7" piece of limestone rock which comes with a display stand. It's associated with a very small Carpoid fossil that measures about .3" long. The bright orange coloration is due to the oxidization of iron pyrite.

Comes with an acrylic display stand.

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.

The carpoids may be related to the most primitive chordates or vertebrates and are ancestral to the more advanced echinoderms.
