Mammals are cynodonts, as are their extinct ancestors and close relatives (Mammaliaformes), having evolved from advanced probainognathian cynodonts during the Late Triassic. Non-mammalian cynodonts occupied a variety of ecological …

Cynodont, any of a group of mammal-like reptiles of the order Therapsida that existed from the late Permian to the early Cretaceous Period. Cynodont skulls have many features that anticipate those found in mammals, and fossil evidence suggests that mammals evolved from cynodonts early in the Jurassic Period.

Oct 6, 2016 · The analysis of two newfound species of cynodont, a group that gave rise to all living mammals, sheds light on how mammals developed from these late Triassic creatures, the researchers said.

Cynodonts are direct ancestors of mammals. Their advanced jaw structure, specialized teeth, and development of middle ear bones were critical in the evolution of mammals. Some cynodont lineages evolved into the first mammals during the Late …

They were one of the most diverse groups of therapsids. They are named after their dog -like teeth. Cynodonts have nearly all the characteristics of mammals. Their teeth were fully differentiated, the braincase bulged at the back of the head, and many of them walked in an upright manner unlike reptiles.

The Cynodonts are a sub-order of the Therapsida. Cynodonts, one of the most diverse groups of therapsids, are named after their dog-like teeth. The taxon is a clade which includes modern mammals and their extinct close relatives, the Mammaliaformes.

Eucynodontia ("true dog teeth") is a clade of cynodont therapsids including mammals and most non-mammalian cynodonts. The oldest eucynodonts are known from the Early Triassic and possibly Late Permian. Eucynodontia includes two major subgroups, Cynognathia and Probainognathia. [1]

Oct 5, 2016 · Research by Agustín Martinelli and colleagues from Brazil has now revealed two new species of probainognathian cynodont from the Late Triassic, around 230 million years ago, of the Rio Grande do Sul state in southern Brazil.

The cynodonts are a very well-known and intensely studied volume of phylospace. In particular, a series of interdependent changes in the cynodont head -- mostly soft tissue changes -- has been the focus of much science and not a little inspired speculation.

Bonacynodon is named for Argentine paleontologist José Bonaparte and the term cynodont (Greek for dog-toothed), a term applied to the part of the mammalian lineage that has fully differentiated incisors, canines, and post-canines. The specific name honors Brazilian paleontologist Cesar Schultz.
