Classification

The family Encrinasteridae was originally named by Charles Schuchert in 1914 as a monotypic group containing only the genus Encrinaster.[1] Later authors assigned more genera to the family, and two subfamilies, Encrinasterinae and Armathyrasterinae, were proposed based primarily on the arrangement of the adambulacrals (ossicles lying along the ambulacral grooves) in 1978.[2]
