Leptobos is an extinct genus of large bovine, known from the Late Pliocene and Early Pleistocene of Eurasia.

Contents

Distribution

The range of Leptobos extended from the Iberian Peninsula to northern China. [1] L. merlai is known from the Early Pleistocene of central Italy. [2]

Description

Species of Leptobos weighed on average 320 kilograms (710 lb). [3]

Evolution

The first appearance of Leptobos in Europe around 3.6-3.5 million years ago is considered to define the beginning of the Villafranchian European faunal stage. [4] Leptobos is considered to be closely related to the insular genus Epileptobos from the Pleistocene of Java [5] , and is considered to be ancestral to Bison . [1] [6] Leptobos became extinct after being replaced by their descendant Bison during the Early Pleistocene, after a period of temporal overlap. [1] [6] "Leptobos" syrticus from Libya likely belongs in a different genus. [5]

Palaeobiology

The dietary preference across the genus includes species that were browsers, [7] grazers [8] and mixed feeders. [9] Ecomorphological analysis of its humerus suggests that L. etruscus was adapted for open grassland habitats. [10]
