Triconodontidae is an extinct
Triconodontids can be distinguished from other eutriconodonts by the shape of their
mammaliaform Morganucodon.[4] However, a 2020 study on Priacodon suggests that triconodontids occluded their molars in the same manner as other eutriconodonts (so-called "embrasure occlusion"), with the middle cusp (cusp A/a) fitting between two opposing molars.[5]
Taxonomy
Triconodontidae was named by Marsh (1887). It was assigned to
Mammalia by Marsh (1887) and Luo et al. (2001).[6]
Sometimes
Volaticotheria is recovered as a part of this group.[2] However, other phylogenetic studies group it outside of Triconodontidae.[7][8]
