Rustaviornis is an extinct monotypic genus of pheasant-like bird. Its remains were discovered in Miocene-aged sediments near Rustavi, in Eastern Georgia.[1]
History and etymology
[edit ]The genus Rustaviornis was erected in 1972 by Burchak-Abramovich and Meladze, based on a single distal fragment of a tibiotarsal bone, found in the right bank of the Kura, near the town of Rustavi, in modern Georgia, that was at the time a Union Republic of the USSR.[1]
The genus name, Rustaviornis, is formed by the prefix Rustavi-, referring to the town of Rustavi near which it was found, and the suffix -ornis, meaning "bird".[1]
Description
[edit ]Rustaviornis is only known after a single and fragmentary holotype tibiotarsus, sharing similarities with those of modern-day pheasants and black grouse, although it was much larger, reaching the size of that of the modern junglefowl.[1]
Paleoecology
[edit ]During the Early Miocene, the Iagluja locality, as well as several other sites in the area, was populated by a typical European Hipparion fauna, such as a Mediterranean tortoise, an undeterminate rodent, a badger, the skunk Promephitis , the hyenas Ictitherium and Adcrocuta , a saber-toothed cat, the early elephant Choerolophodon pentelicus , the namesake horse Hipparion cf. eldaricum, a chalicothere, the rhinoceros Dicerorhinus and Aceratherium , the hog Microstonyx , the deer Procapreolus , the giraffid Palaeotragus , and the bovids Oioceros , Paraoioceros and Tragocerus .[1]
