Material belonging to "Narynsuchus" consists of large and characteristically striated teeth as well as a robust left tibia. "Narynsuchus" is thought to have been larger than Sunosuchus, another crocodyliform from Sarykamyshsai 1, due to the greater size of the known elements belonging to the genus. This material was first recognized as belonging to a new crocodyliform in 1989, when it was referred to as an indeterminant species of Peipehsuchus.
