A new Eocene bird species has been discovered in the Uinta Formation in the Uinta Basin of Utah. Dubbed informally as the Uintan paraortygid (yet to be formally named), this bird species lived about 44 mya and belongs to a family of extinct birds known as Paraortygidae that are related to living Galliformes (like chickens, turkeys & quails) and fossils from this group have been found in Europe, Asia, Africa & North America. The species is know from a coracoid bone. The authors state that these small ground-dwelling birds may have been competing with early mammals for resources http://www.sci-news.com/paleontology/uintan-paraortygid-08189.html https://www.mdpi.com/1424-2818/12/3/90 (Stidham, Townsend & Holroyd., 2020)
