The saola, siola, Vu Quang ox, spindlehorn, or Asian bicorn, also, infrequently, Vu Quang bovid (Pseudoryx nghetinhensis), is one of the world’s rarest large mammals, a forest-dwelling bovine found only in the Annamite Range of Vietnam and Laos. Related to cattle, goats, and antelopes, the species was defined following a discovery of remains in 1992 in Vũ Quang Nature Reserve by a joint survey of the Vietnamese Ministry of Forestry and the World Wide Fund for Nature. - Pseudoryx nghetinhensis
Assessment and conclusions are based in part on information exchanged among researchers at recent meetings of the Saola Working Group of the IUCN SSC Asian Wild Cattle Specialist Group (Saola Working Group 2009, 2013). - Rediscovering the Saola – Panda – WWF
