Titanoperdix

Titanoperdix is only known from a single holotype fragment of a coracoid, that appeared similar to that of modern "true" partridges and pheasants. Substantial differences in its anatomy allowed however to erect the animal into a distinct genus. The 20 cm long coracoid was substantially larger than that of modern species of partridges, indicating that Titanoperdix reached the size of a male black grouse.^[1]

The environment preserved in the Malye Goly locality preserves an important and rare view of the paleoenvironment of Eastern Siberia. The local avifauna is predominantly composed of waterbirds, including a modern common shelduck, an indeterminate sea duck potentially related to the modern goldeneye, the diminutive teal Sibirionetta formozovi, two other indeterminate genera of ducks, a grebe, the extinct crake Porzana payevskyi and a sandpiper, although terrestrial birds, such as Titanoperdix, a specimen associated to the modern Daurian partridge and a corvid were also present. Based on this fauna, the environment appears to be the ancient shoreline of a lake, along with a riverine ecosystem and open steppe-like environments in the hinterland.^[1]
