What is the animal Dvinia known for?

Dvinia is an extinct animal that belonged to the group of cynodonts, which were close relatives of mammals.
Dvinia is known for having a large opening in its skull behind the eye, which allowed more space for the jaw muscles.
This feature is typical of advanced therapsids, which were the ancestors of mammals.
Dvinia also had a specialized dentition, with small incisors, two canines, and 10-14 postcanines, which suggest that it was an omnivore that could eat both plants and animals.
Dvinia lived in Russia during the Late Permian period, about 265-252 million years ago, and shared its habitat with other therapsids such as Inostrancevia, Scutosaurus, and Vivaxosaurus.

Where does the Dvinia live?

Dvinia is an extinct genus of cynodonts, a group of mammal-like reptiles that are the ancestors of modern mammals.
Dvinia lived in the Late Permian period, about 259 to 252 million years ago, on the territory of present-day Arkhangelsk Oblast, Russia.
It was a small animal with specialized cheek teeth, probably omnivorous.
It was one of the first cynodonts to show signs of warm-bloodedness, as its nasal cavity was divided into ethmoidal and maxillary turbinates, which are structures that help warm the inhaled air.
Dvinia was the only member of the family Dviniidae.
Dvinia was discovered by Professor Amalitsky in 1899 on the Northern Dvina River (hence the name), in bone lenses of sands "Sokolki", near the village of Novinki, under the city of Kotlas.
Dvinia is one of the representatives of the Severodvinsk fauna, a unique assemblage of Permian vertebrates that inhabited the northern part of the ancient continent of Pangaea.
Dvinia had a slender body, a long tail, and a relatively large head with a short snout.
Its skull was about 12 cm long, and its total body length was estimated at 50 cm.
