Ferganastegos is a dubious genus of stegosaur from the Middle Jurassic (Callovian) Balabansai Formation of Fergana Valley, Kyrgyzstan.[1][2]

Description

The holotype of Ferganastegos callovicus, IGB 001, consists of four posterior dorsal vertebrae.[3] Although Averianov et al. did not consider the vertebrae diagnostic to genus, the freelance Russian dinosaur enthusiast and amateur paleontologist Roman Ulansky decided that the differences between IGB 001 and other stegosaurs were sufficient to warrant a binomial for IGB 001, Ferganastegos callovicus (Callovian roof from Fergana Valley), despite the fact he did not examine the material himself.[1] Other researchers still contend that the material is not diagnostic and that the genus is a nomen dubium.[4]

Biology

Based on present of stegosaur diet, Ferganastegos would have been a low-browsing herbivore.
