Dear Charlie,

Thanks for the reference to this recent VanLandingham paper. Together with the earlier ones, the Valsequillo case gets increasingly intriguing. I wonder what Waters thinks about all this.

By the way, do you know VanLandingham's email address. I would like to ask him a few questions, both general and specific.

Jacques

VanLandingham, S.L., 2009, Use of diatom biostratigraphy in determining a minimum (Sangamonian = 80,000--ca.220,000 yr. BP) and a maximum (Illinoian = 220,000--430,00 yr. BP) age for the Hueyatlaco artifacts, Puebla, Mexico. Nova Hedwigia (February, 2009), Beiheft 135, p. 15-36.

Abstract: The diatom biostratigraphy presented herein establishes a minimum (Sangamonian) and a maximum (Illinoian) age for the younger (bifacial) artifacts at the Hueyatlaco archaeological site in units B,C, and E, Puebla, Mexico. One of the 13 samples in this study is from a position of Sangamonian age which is stratigraphically higher than the artifacts. The minimum age of this sample (from unit B) is demonstrated by 6 taxa which became extinct at the end of the Sangamonian , and its maximum age (also Sangamonian) is denoted by 3 taxa with earliest known first occurrences in the Sangamonian. The diatoms of the remaining 12 samples have a minimum age of Sangamonian. Three of the 13 samples are in unit I and no Hueyatlaco artifacts are known below this unit.

Abstract: Bona fide artifacts have been found in situ in sedimentary deposits which, by various reputable means (including fossil cysts), have been demonstrated to be older than the Last Ice Age, but most American archaeologists disagree. No other archaeological site in the world is known to be associated with such highly significant age and environmentally diagnostic cyst/diatom evidence as Hueyatlaco. Two diagnostic Yarmouthian (430,000 - 500,000 yr BP) cyst assemblages (in samples VL2149 and VL2316) occur in a bed (Unit J) which is conformably below (and older) than the lowermost artifact-bearing bed (Unit I) at the Hueyatlaco archaeological site. And these two samples correlate with a third diagnostic Yarmouthian sample (68M288=VL2243) from a core 7 km NNW at Rancho Batan. The extinctions and earliest known first occurrences of the 26 extant and 8 extinct cyst taxa in the three samples (with a minimum 430,000 yr BP Yarmouthian age) corroborate a maximum of 430,000 yr BP age for the Hueyatlaco artifacts which previously was established by means of cyst/diatom assemblages with a maximum age of Illinoian (220,000 - 430,000 yr BP) in Unit I.

Dear Marc Washington,

This is to inform you that I have had enough of your never ending pseudo-archaeological absurdities and I would like to think that most Forum members feel the same way.  Ergo, I'll shortly begin to delete all your irrelevant posts and if more of the same happens to recur, I'll have to to delete your membership.

Robert,
Sorry, I have not studied the early New Guinea/Australian crania. However it might be pertinent to your research to review some of the papers by Marta Lahr @ Cambridge. She has studied some possible causes for 'cranial robusticity'. Somewhere I have one of her papers discussing robusticity versus latitude in Patagonia/Tierrs del Fuego.

The robust,archaic Coobool Creek,Kow Swamp [ca 16.8-8.4Ka],
WLH 50 [ca14Ka] and Cossack [ca 6.0Ka] skulls are anomalous,
when compared to the older WLH 1,WLH3 and Tasmanian crania.
Stimulated luminescence measurements dated the sediments by
the Kow Swamp remains and cultural material to ca 22-17Ka [T
Stone,2003].This method does not record the date of the burial.

Kow Swamp skulls have flat receding foreheads,thick vaults,
heavy supra orbital ridges and prognathic faces.Some mandibles
have huge teeth and jaws [A Terne,1977].Kow Swamp 1 and5
have been cited as evidence for the cultural modification of the
frontal bone [A Durband,2009].S Webb[in J Flood,2001] suggests
that replacement of the exterior and interior tabular bone of the
massive WLH 50 skull with diplasic tissue might be related to
genetic disorder.It could have been  defense against malaria.
Regardless of the pathological change WLH 50 has very robust
cranial characteristics [A Durband,2009]. C Stringer [1991]
noted that WLH 50 had affinities with Qafzeh/Skhul skulls.
The cranial morphology of Cossack man,which was recovered
In the warm climes of NW Western Australia,shares a number
of features with the Kow Swamp specimens [J Flood,2001].

T Stone [2003] proposed that the struggle for survival during
The LGM had altered the characteristics of the Kow Swamp
and Coobool Creek skulls.This is difficult to rationalize.There
is no definitive of cranial change among Tasmanians during
the LGM.New Guinea highlanders  have robust features,
heavy bones,and strong supraorbital ridges.They share some
traits in common with Qafzeh/Skhul,Patagonian Tierra del
Fuegens,and a number of the more archaic Australian crania
P Ferdinando [2002].The Talgai skull from SE Queensland
belongs to a 15 year old male,who suffered a severe blow
to the head ca 11??Ka.The reconstruction of the crania
is sub-standard.The rugged archaic skull is robust with a
retreating low forehead and prognathic face.His palate and
teeth are very large.Deformation may have emphasized
these traits [Macintosh,1967].

Ca 18-16 Ka the New Guinea mountain valleys above 3700m
asl were glaciated.Snowline and pollen data imply that
temperatures in the highlands were 8-10C lower than and about
1-2C lower in the lowlands [B Mark,2005]The harsher climate    
Conditions “might” have motivated  a group of New Guinea
Highlanders to begin a long trek southward towards Kow
Swamp [blatant speculation].
   
DNA analysis tends to lend minimal support to this premise.
Most of the genetic studies infer an ancient common
ancestry between the earliest colonists of Australia and New
Guinea.G Hudjashovet [2007] identified an mtDNA
Kalumburu,north Queensland,sample,which exhitited most of
The basic mutations,that are characteristic of haplogroup Q.
This lineage  is deemed to have arrived in Australia from New
Guinea before rising sea level severed [ca 8Ka] the landbridge
between the two countries.

If anyone has sighted detailed cranial information on New
Guinea highlanders,could they please supply a reference or
article.Any comments on the above would be appreciated.

There was a symposion about this question in Tübingen some years ago and the answer was : probably  NO, especially in the Swabian Region. A new publication claims that Neanderthals and modern humans could have met in the Charente region.

"Cutmarked human remains bearing Neandertal features
and modern human remains associated with the
Aurignacian at Les Rois"

http://www.isita-org.com/jass/Contents/2009%20vol87/PDF/On-Line_bassa/JASs2009_06_RamirezRozi.pdf


From the Summary -  The view that Aurignacian technologies and their associated symbolic manifestations
represent the archaeological proxy for the spread of Anatomically Modern Humans into Europe, is supported
by few diagnostic human remains, including those from the Aurignacian site of Les Rois in south-western
France. Here we reassess the taxonomic attribution of the human remains, their cultural affi liation, and
provide fi ve new radiocarbon dates for the site. Patterns of tooth growth along with the morphological and
morphometric analysis of the human remains indicate that a juvenile mandible showing cutmarks presents
some Neandertal features, whereas another mandible is attributed to Anatomically Modern Humans.
Reappraisal of the archaeological sequence demonstrates that human remains derive from two layers dated
to 28–30 kyr BP attributed to the Aurignacian, the only cultural tradition detected at the site.  ree possible
explanations may account for this unexpected evidence. The first one is that the Aurignacian was exclusively
produced by AMH and that the child mandible from unit A2 represents evidence for consumption or, more
likely, symbolic use of a Neandertal child by Aurignacian AMH.  e second possible explanation is that
Aurignacian technologies were produced at Les Rois by human groups bearing both AMH and Neandertal
features. Human remains from Les Rois would be in this case the first evidence of a biological contact
between the two human groups.  e third possibility is that all human remains from Les Rois represent an
AMH population with conserved plesiomorphic characters suggesting a larger variation in modern humans
from the Upper Palaeolithic.

Thanks Johannes,

Although I had only access to the two papers asbstracts , this is extremely interesting.

The very early manifestation of representative art is my main subject of interest in prehistory. Although we will never know if there were other representative art production on supports that didn't pass the test of time, any new finding of preserved art that pushes back in time the manifestation of human abstraction capabilities through representation of a subject adds to the marvel of early human culture evolution.

Yours.

The team of Tübingen (Conard et al.)  report the discovery of a female mammoth-ivory figurine in the basal Aurignacian deposit at Hohle Fels Cave in the Swabian Jura of southwestern Germany during excavations in 2008. This figurine was produced at least 35,000 calendar years ago, making it one of the oldest known examples of figurative art.

The whole story can be found HERE: http://www.nature.com/nature/journal/v459/n7244/full/nature07995.html

A short comment by Paul Mellars: http://www.nature.com/nature/journal/v459/n7244/full/459176a.html

Besinde the figurine from Krems-Stratzing ("Fanny")  which may be femal, this is the first "venus" from a secure Aurignacien context

I agree, we need more specimens. However the evidence has been gradually mounting against the microcephalic camp and for a genuine new (or old!) species.

Did you see the article about the wrist below, particularly the transition between chimpanzees/hobbit/H. sapiens? I found it pretty convincing, or at least consistent with the proposal that the hobbit was not just a microcephalic modern human.
