Lanthanosuchoidea is an extinct superfamily of ankyramorph parareptiles from the late Cisuralian to the middle Guadalupian epochs (Artinskian^[1] - Wordian stages) of Europe, North America and Asia. ^[2] It was named by the Russian paleontologist Ivachnenko in 1980, and it contains two families Acleistorhinidae and Lanthanosuchidae.^[3]

Phylogeny

Lanthanosuchoidea is a node-based taxon defined in 1997 as "the most recent common ancestor of Lanthanosuchus, Lanthaniscus, and Acleistorhinus".^[3] The cladogram below follows the topology from a 2011 analysis by Ruta et al.^[2]
