A new Devonian asteroid-like ophiuroid from Spain by D.B. BLAKE, S. ZAMORA, J.L. GARCÍA-ALCALDE

“…Ophiocantabria is assigned to the Encrinasteridae based on the morphology of individual skeletal elements, although overall form of the new species is similar to that of approximately coeval members of the asteroid family Xenasteridae. Such homoplasy, especially among earlier members of asterozoan class-level clades, is an important but not well understood aspect of subphylum evolution. …”
