Lanthanosuchoidea

Lanthanosuchoidea is an extinct superfamily of ankyramorph parareptiles from the middle Pennsylvanian to the middle Guadalupian epoch (Moscovian[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]

gollark: I bet it's CGNAT. Turkey probably lacks IP addresses.
gollark: I got bored a few days back and connected the osmarks.tk servers to yggdrasil and reconfigured my webserver so they're reachable over it.
gollark: Like yggdrasil or cjdns.
gollark: You can use one of those cool overlay network things instead of "hamachi".
