Biology:Orientornis
Orientornis is an extinct species of ratite from the Miocene of China.[1]
Description
Remains of a pelvis, including a synsacrum, were recovered from mudstone in the Linxia Basin, Guanghe County, Gansu Province, northwest China. Based on the size of these remains, it is believed to have been slightly larger than Struthio camelus. When this bird lived, the area is believed to have been either open grasslands or wetlands.[1]
Taxonomy
Orientornis was originally named as a species of Struthio, S. linxiaensis, by Hou et al. (2005).[1] However, Wang (2008) placed the taxon in its own genus, Orientornis.[2]
Mikhailov and Zelenkov et al (2020) have disputed the validity of this genus, treating Orientornis as a junior synonym of Struthio, and noting that a direct comparison with Struthio wimani is required, as both taxa may represent the same species.[3]
