Early cynodonts have many of the skeletal characteristics of mammals. The teeth were fully differentiated and the braincase bulged at the back of the head. Outside of some crown-group mammals (notably the therians), all cynodonts probably laid eggs.

Los cinodontos (Cynodontia, griego «dientes de perro») son un clado de terápsidos que aparecieron por primera vez en el Pérmico Superior, hace unos 260,4 millones de años. El grupo incluye a todos los modernos mamíferos, así como a …

cynodont, (clade Cynodontia), any of a group of mammal-like reptiles of the order Therapsida that existed from the Late Permian to the Early Cretaceous Epoch (259.5 million to 100.5 million years ago). Fossil evidence suggests that mammals evolved from cynodont stock early in the Jurassic Period (201.3 million to 145.0 million years ago).

The cynodonts ('dog teeth') (clade Cynodontia) are a clade of therapsids that first appeared in the Late Permian (approximately 260 Ma), and extensively diversified after the Permian–Triassic extinction event. Cynodonts had a wide variety of lifestyles, including carnivory and herbivory.

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.

In the unbroken evolutionary sequence from reptile to mammal, the cynodonts are intermediate between earlier and more primitive theriodont therapsids and the earliest mammals.

Esses animais primitivos eram os cinodontes, grupo que começou a desenvolver as características que hoje são exclusivas dos mamíferos: sangue quente, pelos sobre o corpo e diferentes tipos de dentes na boca – em latim, cinodonte significa dentes de cão.

Even the earliest cynodonts, the Procynosuchidae of the Late Permian, show many advanced mammalian characteristics, such as a reduced number of bones in the lower jaw, a secondary bony palate and a complex pattern of the crowns of their cheek teeth.

Cynodontia ou cinodontes (dentes-de-cão) é um táxon de terapsídeos que apareceu pela primeira vez no final do Permiano e se distribuíram por todos os sete continentes no Triássico. [1] Este clado inclui os mamíferos — modernos e extintos — e os seus parentes mais próximos.
