Holasteroida

Lateral and oral views of Echinocorys scutatus, from Wagner & Durham (1966).


Belongs within: Atelostomata.

The Holasteroida are a diverse group of mostly deep-water irregular echinoids known from the Lower Jurassic to the present. They exhibit a wide variety of forms; the primarily bathyal Pourtalesiidae are among the most unusual of all echinoids, with a more or less elongate, bottle-shaped test (Wagner & Durham 1966).

Characters (from Wagner & Durham 1966): Apical system typically elongate or disjunct, no genital 5; plastron feebly differentiated or meridosternous; petals not always differentiated, paired petals typically not impressed; no floscelle; apical system and peristome may be opposite to one another; fascioles variable.
