Rare Dendrocystoides from Starfish Beds of Girvan Scotland

Description: Presented is an exceptionally rare find from the world famous Starfish Beds of Girvan Scotland. This is the only one I have to offer. Please don’t delay if this is on your collection wish list.

Cystoids include any member of an extinct class (Cystoidea) of primitive echinoderms (animals with a hard, calcareous external skeleton, related to the modern sea lily and starfish) that first appeared during the Middle Ordovician epoch and persisted into the Late Devonian epoch (the Ordovician Period began about 488 million years ago, and the Devonian Period ended 359 million years ago). Once diverse and important, the cystoids had sack-like bodies that were attached to a stem anchored to the seafloor. Numerous plates covered the body.
