Prozostrodontia

Clade of cynodonts

Prozostrodontia is a clade of cynodonts including mammaliaforms and their closest relatives such as Tritheledontidae and Tritylodontidae. It was erected as a node-based taxon by Liu and Olsen (2010) and defined as the least inclusive clade containing Prozostrodon brasiliensis, Tritylodon langaevus, Pachygenelus monus, and Mus musculus. Prozostrodontia is diagnosed by several characters, including:Reduced prefrontal and postorbital bones, with the disappearance of a strut of bone called the postorbital bar separating the eye socket from the temporal region Unfused symphysis between the dentary bones in the lower jaw The presence of a small hole within the eye socket called the sphenopalatine foramen A long sagittal crest extending to the rearmost part of the lambdoidal crest at the back of the skull Neural spines of the dorsal vertebrae angled backward A convex-shaped iliac crest and a reduced posterior iliac spine on the hip An acetabular notch on the ischium The position of a small projection called the lesser trochanter close to the head of the femur
