† ORDER POLLICIPOMORPHA ORD. NOV. (JURASSIC–RECENT)

Diagnosis: Capitulum includes a large number (20– 40+) of imbricating, secondary lateral plates, which decrease in size towards the basal margin.

Comment: This group was abundant and widespread in the Upper Jurassic and Cretaceous ( Zeugmatolepadidae; see Gale, 2014a, 2020a). Extant Pollicipedidae (Capitulum and Pollicipes) extend back into the Cretaceous and, with Lithotryidae, form a group that always cluster closely together in the molecular analyses.
