Oioceros fossil map
Where fossils of Oioceros have been found, shown on the Earth as it looked about 5 million years ago and on today’s map.
Dots are fossil collections recorded in the Paleobiology Database. The “then” view moves today’s fossil sites back to their positions 5 million years ago (the time slice nearest the median age of the fossils) using the Merdith et al. (2021) plate model; positions are approximate. Open on the timeline map →

About Oioceros
Oioceros is an extinct genus of spiral-horned antelope from the late Miocene. Its fossils have been found in Greece, China, Iran, and Africa. It was first discovered by Wagner in 1857, and contains nine species, O. rothii, O. atropatenes, O. jiulongkouensis, O. noverca, O. robustus, O. stenocephalus, O. lishanensis, O. wegneri, and O. tanyceras. Former species include O. grangeri (Pilgrim, 1934), now recognized as the genus Sinomegoceros, and O. xiejiaensis (Li and Qui; 1980), now recognized as the genus Sinopalaeoceros.
Oioceros somewhat resembled a gazelle.
