Arctotraversodontinae is a subfamily of Late Triassic cynodonts belonging to the family Traversodontidae. Members of the subfamily include Arctotraversodon , Boreogomphodon and Plinthogomphodon from North America, and Habayia , Maubeugia , Microscalenodon and Rosieria from Europe. [1]

Classification

The subfamily was erected in 2020 by Hendrickx et al., who defined it as all traversodontids more closely related to Arctotraversodon plemmyridon than to Massetognathus pascuali or Gomphodontosuchus brasiliensis . [1] In their cladistic analysis, they found Arctotraversodontinae to be the sister taxon of the subfamily Gomphodontosuchinae. Below is a cladogram from that analysis: [1]
