Colobus flandrini

Colobus flandrini is an extinct species of colobus monkey that lived in Africa during the Miocene, about 10 million years ago, and its fossils come from Algeria. It is the oldest known colobus monkey and one of only two extinct species of true colobus monkey described so far, the other being Colobus freedmani. It was larger than its living relatives, with an estimated weight of about 21 kilograms. Its fossils were first assigned to the macaque genus Macaca by Arambourg, and they were given their current placement in Colobus by Delson in 1973, which is the work that settled where the species belongs.
