Chroniosuchia
Chroniosuchia is a group of tetrapods that lived from the Middle Permian to Late Triassic in what is now Eastern Europe, Kyrgyzstan, China and Germany. Chroniosuchians are often thought to be reptiliomorphs, but some recent phylogenetic analyses suggest instead that they are stem-tetrapods. They were all rather short limbed with a strong tail and elongated snout, somewhat resembling modern crocodiles. The group is traditionally considered to be a suborder or order of labyrinthodonts. Chroniosuchians likely had ecological niches as riverside predators, and may have been outcompeted by semiaquatic true reptiles such as phytosaurs in the late Triassic. Most forms bore a heavy armour of scutes along the back, possibly for protection against land born predators like therapsids, or to strengthen the axial skeleton for terrestrial locomotion. Indeed, femoral microanatomy of ''Chroniosaurus'' suggests that it was amphibious to terrestrial. Description The most distinguishing features o ...

Chroniosuchidae
The Chroniosuchidae are a family of semi-aquatic reptiliomorph amphibians found in sediments from the upper Permian and the upper Triassic periods, most in Russia. They were generally rather large animals, with long jaws similar to those found in modern crocodiles, and probably lived a similar life style as riverside piscivores and ambush predators. Like all Chroniosuchians, they bore extensive osteoderm armour on their backs, possibly as protection against terrestrial predators such as the Permian therapsids and the Triassic Rauisuchians. Phylogeny Below is the cladogram from Buchwitz ''et al.'' (2012) showing the phylogenetic relations of chroniosuchids: See also * Permian tetrapods Permian tetrapods were amphibians and reptiles that lived during the Permian Period. During this time, amphibians remained common, including various Temnospondyli and Lepospondyli. Synapsids became the dominant type of animal, represented by the P ...

Bystrowiana Permira
''Bystrowiana'' is an extinct genus of bystrowianid chroniosuchian from upper Permian deposits of Vladimir Region, Russia and Jiyuan, China. Chroniosuchians are often thought to be reptiliomorphs, but some recent phylogenetic analyses suggest instead that they are stem-tetrapods.

Axitectum
''Axitectum'' is an extinct genus of bystrowianid reptiliomorph from lower Triassic deposits of Nizhni Novgorod and Kirov Regions, Russia. It was a rather large animal judging by the size of its vertebrae. The back was covered in bands of highly ornamented osteoderm plates, similar to those found in modern crocodiles. The bands overlapped with the next band at the posterior end. Michael J. Benton, Mikhail A. Shishkin and David M. Unwin (2003): The Age of Dinosaurs in Russia and Mongolia. Cambridge University Press, Cambridge UK.Relevant pagefrom google books It was first named by M.A. Shishkin and I.V. Novikov in 1992 and the type species is ''Axitectum vjushkovi''. ''A. vjushkovi'' is known from the holotype PIN 1025/334, which consists of armor scute.

Bystrowiella
''Bystrowiella'' is an extinct genus of bystrowianid reptiliomorph from upper Middle Triassic (Ladinian age) deposits of Kupferzell and Vellberg, northern Baden-Württemberg, Germany. It was first named by Florian Witzmann, Rainer R. Schoch and Michael W. Maisch in 2008, from a complete osteoderm fused with tip of neural spine (SMNS 91034, the holotype), partial osteoderms (SMNS 91036, 91037) and vertebrae (SMNS 81698, 81871–81874, 81876, 81877, 81879). The type species is ''Bystrowiella schumanni''. The genus is named in honour of Dr. Alexey Bystrow Alexey Petrovich Bystrow, sometimes spelled Alexey Petrovich Bystrov and Aleksei Petrovich Bystrow, (russian: Алексе́й Петро́вич Быстро́в; February 1, 1899 – August 29, 1959) was a Soviet paleontologist, anatomist, ..., a Russian paleontologist and the species in honour of Schumann family.

Dromotectum
''Dromotectum'' is an extinct genus of bystrowianid reptiliomorph from the Late Permian of China and Early Triassic of Russia. Two species have been named: the type species ''D. spinosum'' and the species ''D. largum''. ''D. spinosum'', the first species to be named, comes from Lower Triassic deposits in the Samara Region of European Russia and is known from the holotype PIN 2424/23, which consists of armor scutes, and from PIN 2424/65, 4495/14 and 2252/397. It was found in the Staritskaya Formation of the Rybinskin Horizon and named by I.V. Novikov and M.A. Shishkin in 2000. The generic name means “corridor with hipped vault” (''dromos'' in Greek) + “roof” (''tecton''), and the specific name means “spinous” (''spinosum'' in Latin). A second species, ''D. largum'', was named by Liu Jun, Xu Li, Jia Song-Hai, Pu Han-Yong, and Liu Xiao-Ling in 2014 from the Shangshihezi Formation near Jiyuan in Henan Henan (; or ; ; alternatively Honan) is a landlocked provi ...

Jiyuanitectum
''Jiyuanitectum'' is an extinct genus of chroniosuchian tetrapod from the Late Permian Shangshihezi Formation of China. It is known from a single bony scute from Jiyuan in Henan province, ascribed to the type species ''Jiyuanitectum flatum'' in 2014. Plate-like scutes, which formed armor-like coverings on the backs of chroniosuchians, are the most commonly found chroniosuchian remains. They are also the most informative when it comes to distinguishing between species due to small variations in scute anatomy between different taxa. For example, a shallow groove along the midline of the scute is unique to ''Jiyuanitectum''. The flatness of the scute is another unusual characteristic, giving it the species name ''flatum''. ''Jiyuanitectum'' shares several features in common with the chroniosuchians '' Synesuchus'' and '' Bystrowiella'', including the upper surface of the scute being covered in ridges that are mostly oriented perpendicular to the midline, and the absence of a bony pro ...
