What is the animal Dvinosaurus known for?

Dvinosaurus is an extinct genus of amphibious temnospondyls that lived in western and central Russia during the middle and late Permian, about 265-254 million years ago.
It was first discovered in 1921 by Russian paleontologist Vladimir Prokhorovich Amalitskii near the Northern Dvina River, which gave the genus its name.

Dvinosaurus had a large, triangular head, short limbs, and a long powerful tail.
It was probably a gill-breathing, fully-aquatic tetrapod, similar to modern axolotls.
It fed on small fish and invertebrates.
A typical individual could grow to be about 40 inches (100 cm) in length, but some species could be larger, up to 2.5 meters.

Dvinosaurus belongs to the order Dvinosauria, a group of primitive semi-aquatic to completely aquatic amphibians.
They are characterized by a reduction of the otic notch, the loss of a flange on the rear side of the pterygoid, and 28 or more presacral vertebrae.
The most basal family of dvinosaurs is Trimerorhachidae.
Most other dvinosaurs are placed in the superfamily Dvinosauroidea.

Dvinosaurus is known for being one of the leading fossils of the late Permian (Tatarian stage) of Eastern Europe.
It is part of the Severodvinsk fauna, a diverse assemblage of vertebrates that inhabited the brackish and freshwater environments of the region.
Dvinosaurus is also known for being one of the few temnospondyls that survived the Permian-Triassic extinction event, the largest mass extinction in Earth's history.
However, it did not last long in the Triassic, as it was outcompeted by other aquatic reptiles and amphibians.

Dvinosaurus is an extinct genus of amphibious temnospondyls that lived in regions of western and central Russia during the middle and late Permian, approximately 265-254 million years ago.

Its name is derived from the proximity of its discovery site to the Northern Dvina River.

Dvinosaurus is thought to have been a gill-breathing, fully-aquatic tetrapod, characterized by a large, triangular head, short limbs, and a long powerful tail.

A typical individual could grow to be approximately 40 in (100 cm) in length.

Dvinosaurus was first described by Russian paleontologist Vladimir Prokhorovich Amalitskii in 1921, based on fossils found near the village of Novinki in the Arkhangelsk District.

Later, more specimens were identified and analyzed by other researchers, who classified four more species of Dvinosaurus: D. egregius, D. purlensis, D. campbelli, and D. secundus.

Dvinosaurus was a water-dwelling animal, probably neotenic (like modern axolotls).

It fed on small fish and invertebrates.

It belonged to the Dvinosauria, a group of primitive, eel-like temnospondyls that were most common in the Permian and earliest Triassic.

Dvinosaurus was a guide fossil for the late Permian (Tatarian stage) of Eastern Europe, and part of the Severodvinsk fauna.
