Giraffa jumae is an extinct species of even-toed ungulate in the Giraffidae family. The species ranged from Malawi to Chad with a possible occurrence of the species or a closely related species found in Turkey. The type specimen was discovered during trenching excavations on the upper member of the Rawi Formation by Louis Leakey in the 1930s.[2] The specimen was found with Ceratotherium simum, Suidae such as Metridiochoerus andrewsi, a Hippopotamus gorgops, and a nearly complete pygmy hippopotamus mandible.[2]
