Erythrosuchidae

Erythrosuchus (from , 'red' and , 'crocodile') is an extinct genus of archosauriform reptiles from the early to middle Triassic of South Africa. Remains have been found in the Cynognathus Assemblage Zone of the Beaufort Group in the Karoo of South Africa. In the Late Triassic, the ecological niche left by Erythrosuchus was filled by archosaurs including Saurosuchus and Postosuchus.

Erythrosuchidae (meaning "red crocodiles" in Greek) are a family of large carnivorous basal archosauriforms that lived from the later Early Triassic (Olenekian) to the early Middle Triassic (Anisian). Reaching lengths of over , they represented among the largest apex predators across Pangaea during their existence.

Garjainia is an extinct genus of erythrosuchid archosauriform reptile from the Olenekian of Russia and South Africa. It contains two species, Garjainia prima, from the Yarengian/Yarkenskian Supergorizont of Russia, and Garjainia madiba, from the Burgersdorp Formation (Cynognathus Assemblage Zone A) of South Africa. "Vjuskovia triplicostata", a name assigned to some erythrosuchid fossils from Russia, has been synonymized with Garjainia prima.

Uralosaurus is an extinct genus of erythrosuchid archosauriform known from the Middle Triassic (Anisian stage) Donguz Formation of southeastern European Russia. It contains a single species, Uralosaurus magnus. It was named by Vitalii Georgievich Ochev in 1980 as a species of Erythrosuchus otherwise known from the Triassic of Africa and reassigned to its own genus by Andrey G. Sennikov in 1995.

The first fossils of Shansisuchus were discovered from the Ermaying Formation of Shanxi (Shansi) province in 1964 by Chinese paleontologist Yang Zhongjian. Like other erythrosuchids, Shansisuchus was a large-bodied carnivore with a large, deep skull. Shansisuchus is unique among early archosauriforms in having a hole in its skull called a subnarial fenestra.

Though it is only known from some fragmentary cranial material, the skull is estimated to be around 80 centimeters long, making it one of the largest erythrosuchids known. left|thumb|Due to a breakage in the nasal/maxilla region, these bones were pr

Fugusuchus is an extinct genus of archosauriform, probably the basal-most member of the family Erythrosuchidae. The genus is known from a single fossil from the middle Early Triassic Heshanggou Formation in Shanxi, China. The partial skeleton consists of an incomplete skull, parts of the right forelimb, and an intercentrum. The skeleton, known as GMB V 313, is currently in the Geological Museum of China in Beijing.

Bharitalasuchus is an extinct genus of erythrosuchid archosauriform known from the Middle Triassic Yerrapalli Formation of India. It contains a single species, Bharitalasuchus tapani, known from a holotype and paratype consisting of tooth-bearing cranial fragments (maxillae and possible premaxillae), at least 17 presacral vertebrae, ribs, probable intercentra, fragmentary pectoral and pelvic girdles, a femur, and tibiofibular elements. The discovery and description of this taxon was important for the understanding of not only the age of the Yerrapalli Formation, but also the global distributio
