††ORDER ARCHAEOLEPADOMORPHA ORD. NOV. (JURASSIC–CRETACEOUS)

Diagnosis: Robust forms, in which the peduncle is armoured with eight to ten columns of broad, strongly imbricating plates.

Comment: The phylogenetic position of calcareous forms with few lateral capitular plates and strongly armoured peduncles was discussed by Gale (2015a), who argued that these are basal to Thoracicalcarea .
