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.

These ancient, mammal-like reptiles emerged during the Late Permian period, approximately 260 million years ago, and played a pivotal role in the evolutionary transition from reptiles to mammals. Cynodonts are part of a larger group of animals known as Therapsida, which also includes other early synapsid relatives of mammals.

Oct 6, 2016 · Two weird, mammal-like reptiles that sort of looked like scaly rats, each smaller than a loaf of bread, roamed ancient Brazil about 235 million years ago, likely dining on insects the predators...

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.

Mar 5, 2024 · Using computed tomographic data derived from extensive sampling of the earliest known (late Permian and Early Triassic) cynodonts and selected exemplars of therocephalians and later (Middle Triassic onwards) cynodonts, we describe novel aspects of the endocranial anatomy of these animals.

Oct 5, 2016 · Cynodonts are some of the earliest ancestors of mammals, often referred to as ‘mammal-like reptiles.’ They first arose around 260 million years ago, just before the greatest extinction of all time which claimed 95 percent of all life on Earth.

Mar 12, 2007 · Early mammaliaforms and their extinct relatives, nonmammaliaform cynodonts, have long been the focus of intense research in attempting to unravel how and when major changes toward mammalness occurred. The earliest well-known representatives of cynodonts are latest Late Permian in age.

Cynodonts were a group of animals that lived during the late Permian period, though to the mid Cretaceous period, perhaps from about 250 million to 100 million years ago. Cynodonts had many mammal-like features.

These primitive animals were the cynodonts, a group that began to develop the characteristics that today are exclusive to mammals: they were warm-blooded and had hairy bodies and different types of teeth. In Latin, cynodont means dog teeth.
