Hallucicrania is an extinct clade of procolophonomorph parareptiles from the early Cisuralian epoch (middle Sakmarian stage) to the latest Triassic period (latest Rhaetian stage) of Africa, Antarctica, Asia, Australia, Europe, North America and South America.[1][2]

The clade Ankyramorpha was named by the paleontologists Michael deBraga and Robert R. Reisz in 1996 and given nearly the same definition. They defined it as "the most recent common ancestor of Procolophonia and Lanthanosuchoidea and all its descendants".[3] The following cladogram was found by the analysis of Linda A. Tsuji, Johannes Müller and Robert R. Reisz, 2012.[4]
