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[edit]

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]

Lanthanosuchoidea 

Chalcosaurus rossicus



Lanthaniscus efremovi



Lanthanosuchus watsoni


Acleistorhinidae

Acleistorhinus pteroticus



Colobomycter pholeter
