Laetolia sadimanensis

Laetolia sadimanensis is an extinct galagid primate, a member of the galago family Galagidae, known from the Pliocene of Tanzania. It is the only species of the genus Laetolia and is known from several fragments of lower jaw found in the Upper Laetolil Beds at Laetoli. It was first described in 1987 as a species of Galago, and a separate genus, Laetolia, was erected for it in 2011. The jaw fragments are the whole of the fossil record that the sources describe, so little can be said of its size, diet or way of life beyond its place in the family and its age and place of discovery.
