Orrorin

Even the leg bones we have from Orrorin tugenensis 6 million years ago appear to suggest a bi-pedal posture (though it's harder to know from such incomplete remains).

Heck, Orrorin at 6MYA appears to be a biped jury is still out on Ardipithecus.

Much the same conclusion has been drawn by the respective discoverers of two even older fossils, Orrorin (‘Millennium Man’) and Sahelanthropus (‘Toumai’, below).

Other palaeoanthropologists are sceptical of the claims to bipedality that have been made on behalf of Orrorin and Sahelanthropus by their discoverers.

The show put Ardipithecus in its evolutionary place, about a million years earlier than the famous Lucy skeleton (Australopithecus afarensis), but earlier fossil hominins such as the seven-million-year old Sahelanthropus tchadensis and six-million-year old Orrorin tugenensis are scarcely mentioned.

He believes his Orrorin tugenesis fossils are unique because CT scans reveal unusually intricate details of their internal bone structure.

You might ask about ask if there are other species of Hominids that Luskin forgot to mention that also walked upright: oh, say, Australopithicines (several species), Paranthropines (several species), Kenyapithecus, Ardipithecus, or perhaps several that we're currently unsure as to if they walked upright or not (Orrorin, Sahelanthropus).
