Jaikosuchus
''Jaikosuchus'' is an extinct genus of archosauriform that is likely an erythrosuchid. Fossils have been found from European Russia that date back to the upper Olenekian stage of the Early Triassic.〔Shishkin, M. A., Ochev, V. G., Lozovskii, V. R. and Novikov, I. V. (2000). Tetrapod biostratigraphy of the Triassic of Eastern Europe. ''In:'' M. J. Benton, E. N. Kurochkin, M. A. Shishkin, D. M. Unwin (eds.), ''The Age of Dinosaurs in Russia and Mongolia''. Cambridge University Press, Cambridge. pp. 140-159.〕 The genus is quite poorly known, however, and the remains of other erythrosuchids that are also from the Early Triassic of European Russia such as ''Garjainia'' are much more common.〔Borsuk-Bialynicka, M., Cook, E., Evans, S. E. and Maryafiska, T. (1999). A microvertebrate assemblage from the Early Triassic of Poland. ''Acta Palaeontologica Polonica'' 44(2):167-188.〕 The genus was originally assigned as a new species of the proterosuchid ''Chasmatosuchus'' in 1979, but was later put in its own genus in 1990. It has often been described as a rauisuchian or a basal suchian closely related to rauisuchians rather than the more traditional view of it being a more primitive archosaur.〔http://www.helsinki.fi/~mhaaramo/metazoa/deuterostoma/chordata/archosauria/pseudosuchia/suchia_2.html〕 Despite this, its exact classification within Archosauriformes remains uncertain.
