A.L. 666-1 was discovered in 1994 in Hadar, Ethiopia. It dates to ~2·33 MYA and has been attributed to Homo habilis. A number of Oldowan flakes and choppers were found as well.

OH-65 was found in 1995 in the Upper Bed I at Olduvai Gorge. It dates to 1.942-1.785 mya. OH-65 is a nearly complete maxilla that has been attributed to Homo habilis. It’s morpholoogy is similar to that of KNM-ER 1470 and the authors of the paper announcing the find use that similary to make two arguments.
This overall concordance of the ER 1470 and OH 65 morphologies with that of the type specimen of H. habilis casts doubt on H. rudolfensis as a biologically valid taxon. Consequently, H. rudolfensis (Alexeev) Groves would be a junior synonym for H. habilis Leakey, Tobias, and Napier …
The architectural similarities between OH-65 and ER 1470 support the judgement that late Pliocene hominids from Olduvai Gorge and East Lake Turkana usually assigned to H. habilis instead represent more than one species…
On the surface these seem to be contradictory arguments unless they are arguing that because H. rudolfensis is a junior synonym for H. habilis the species in the H. rudolfensis group have to be named something else. At any rate, below is a picture of OH-65.

I am going to be very busy today so I won’t get an in depth post up on Australopithecus sediba until tomorrow. In the meantime three items jumped out at me so I thought I would, briefly, mention them.

Science Daily has an item concerning the Laetoli foot print study in PLoS One. One bit stands out:
The subjects walked both with normal, erect human gaits and then with crouched, chimpanzee-like gaits.
Film of the latter would be interesting – lord knows we were disappointed with last year’s Ardipithecus special on that score… Speaking of, why is the idea that some of our ancestors were bipedal on the ground but still spent a lot of time in the trees news?
And then there is this (also from Science Daily):
This morphology differs distinctly from our own genus, Homo, who abandoned arboreal life around 2 million years ago and irrevocably committed to human-like bipedalism.
I guess Homo habilis don’t count, eh? I hope the PLoS One article is better (I haven’t read it yet).

Ecobotanical Contexts for African Hominids, by O’Brien and Peters, was published in a book edited by J. Desmond Clark entitled Cultural Beginnings: Approaches to Understanding Early Hominid Life-Ways in the African Savanna.
O’Brien and Peters describe the work they are doing on a project called “Survey of the Wild Edible Plants of Africa”. The point of the survey is to assemble as much information as possible on plant species used by baboons, chimpanzees, and humans in Africa. The eventual inclusion of plants used by gorillas was also mentioned.
