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.

Regourdou 1 is a partial neanderthal skeleton discovered in 1957 near Lascaux. Also discovered were the pedal remains of a second individual.

The Dederiyeh Neanderthal infant was found in Dederiyeh Cave, in Syria, in 1993. The skelton is that of a two year old and dates to 50,000-70,000 years ago.

Sambungmacan 3 was discovered in 1977 and spent some time on the antiquities market, eventually ending up in New York, where its importance was realized. It has since been returned to Indonesia. It is attributed to Homo erectus and may be the skull of a female.

I am starting a new series, similar to “know Your Primate” – which will continue – on hominins. The difference, besides subject matter, will be that instead of discussing species I’ll be posting pictures of individual fossils with some additional commentary as the mood strikes me. First up is Stw 53 from Sterfontein. Stw 53 was discovered in 1976 by Alan Hughes and has been at the heart of debates over South African hominin variability. So much so that last year Curnoe used it as the holotype of a new species. The question of how many species are represented in the South African fossil record is something I am becoming interested in, so I will be taking a more in depth look at the question over the coming months. In the meantime, here is Stw 53:

Nature News mentions a new study on Homo floresiensis that concludes that the fossil is that of a microcephalic modern human. The study is actually published in PNAS (and if someone could send me a copy I would appreciate it – my email is in the about tab). Continue reading

I was hoping to have a more in depth post on this for the upcoming edition of the Four Stone Hearth but I am not going to get it finished in time. Here is the short version.

In the previous post in this series I looked at vitamin D metabolism and the effects of vitamin D deficiency on the skeleton. So, lets talk about Lubenow and Neanderthals. Lubenows discussion of Neanderthals and rickets occurs in chapter 14. He begins the chapter by invoking the Genesis flood to explain the ice ages, which only lasted, according to Lubenow, for 700 years (give or take). Continue reading
