Kipsigicerus is an extinct genus of tragoportacin bovid that inhabited East Africa during the Middle Miocene.^[2] The type species, Kipsigicerus labidotus, was discovered in Fort Ternan, Kenya, and was originally described as a species of Protragocerus . The horn cores were distinct, being highly compressed with each horn growing forward to one another. Because of the unique horn morphology, the genus Kipsigicerus was erected for this species.^[3]

Palaeoecology

Though its palaeoenvironment was forested, the dental microwear patterns of K. labidotus are suggestive of the tragoportacin being a grazing herbivore with some intermediate feeding tendencies. Its premaxillary morphology was geared towards a diet of mixed feeding.^[4]
