Ankyramorpha ("anchor forms") is an
period (latest Rhaetian stage) of Africa, Antarctica, Asia, Australia, Europe, North America and South America.[1][2]
This clade was named in a
procolophonoids, Hallucicrania was originally designed to exclude procolophonoids, which Lee's analysis argued to have split off prior to the divergence between lanthanosuchids and pareiasaurs.[6]
Nevertheless, purely considering the taxa encompassed by their definitions, Hallucicrania and Ankyramorpha refer to an identical grouping.
The following cladogram is simplified after the phylogenetic analysis of MacDougall and Reisz (2014) and shows the placement of Ankyramorpha within Parareptilia. Relationships within emboldened terminal clades are not shown.[5]
