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]


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]


Chalcosaurus rossicus

Lanthaniscus efremovi

Lanthanosuchus watsoni


Acleistorhinus pteroticus

Colobomycter pholeter
