Narynsuchus is an extinct genus of giant Goniopholidid Crocodylian. Because it has not yet been formally described, it is currently considered a nomen nudum. The name was first used in 1990 for fossil material found from a formation called the Balabansai Svita, which forms a lens in site FTA-30 of the Sarykamyshsai 1 locality in the Fergana ValleyofKyrgyzstan.[1] The formation dates back to the Callovian stage of the Middle Jurassic.[2] The type species of "Narynsuchus" is "N. ferganensis".Being semi-aquatic it is very similar to modern crocodiles. It ranged from 7–8 metres in length, and would have had a very similar lifestyle to the American alligatororNile crocodile.
Material belonging to "Narynsuchus" consists of large and characteristically striated teeth as well as a robust left tibia.[3] "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.[2] This material was first recognized as belonging to a new crocodyliform in 1989, when it was referred to as an indeterminant species of Peipehsuchus.[3]
