The Lepidocystidae are an extinct family that constitute the most basal known group within the paraphyletic class "Eocrinoidea", and therefore within the subphylum Blastozoa as a whole. Its members, along with the transitional Felbabkacystidae, are also known as "imbricates" or "imbricate Eocrinoids" after the likewise paraphyletic order Imbricata.
