Discokeryx is an extinct genus of even-toed ungulates, possibly related to the modern giraffe and okapi.

D. xiezhi was alive during the Early Miocene period 17–16.9 million years ago.

Fossilized remains of this animal were discovered in the Halamagai Formation located in northwest China.

[1][2] Discokeryx had a thick-boned cranium which had disk-shaped headgear located in the middle of the head, cervical vertebrae with thickened centra, and the most complicated head-neck joints in any mammal known at the time of its discovery in 2022.

Tooth enamel isotopes indicate that the species was an open-land grazer which drank from multiple sources of water, and that their habitats included areas that other contemporary mammals were not adapted to make use of like D. xiezhi could.
