There are already two known likely HSIE major geological structures.

I can not discuss the new candidate crater publicly here for the reasons stated.

IMO, the problem of the peopling of the Americas can be solved by looking at the mt DNA distributions. I've posted notes on them here at archaeologica, along with some rough dates.

The riddle wrapped up in an enigma may be occurring simply because the field is amazed at the answers they are getting from the data. Very early man in SE Asia being another example of this.

BTW, Farpoint....

The women in my group who run Facebook want to know if they can post your "golden with the cats" photo? I don't do FB myself....an enormous time suck and I'm busy enough.... but I have to humor them.

Fair warning, I am PWI.

The women here say that that would be fine as long as they get proper billing; heh heh.

The golden is ELE; not a misspelling, figure it out.

The tuxedo kitty's formal name is Robert Tuvak, but we call him "Bob".

The gray tiger, who moves for no one, is Lobo.

If you look closely at the "golden with the cats" photo, there is a white paw at the bottom of the photo, that would be KC; pronounced "Casey".

ELE = Extinction Level Event?

"He shall know your ways as if born to them."

You are correct, you know me so well so quickly, "it is not a matter of if, it is a matter of when" (Ice, Sir Fred Hoyle, 1981).

Now, back to the subject at hand, the Lateglacial period, 13.5 to 12.8 calybp, in Beringia, saw cooling temps, the extinction of the mammoth, expansion of shrub tundra, an open Ice Free Corridor, and a change in lithics, on both sides of the still available land bridge, somewhat away from the microblade industry to a leaf shaped and an occasional bi-face (Hoffecker and Elias, 2007). Clovis were well entrenched far to the southeast with well developed bi-face technology at that time. Swan Point, dated at 14.3 calybp, is microblade, and one of the oldest still accepted eastern Beringian sites; eg. Bluefish cave data has fallen apart.

So, we are still looking for boats.

Ahh, boats. If only you knew how long we've been looking for boats on this site. i think you're fitting in quite well here Farpoint.

I don't expect to find a boat.

But finding organisms across the sea implies that the got there somehow and walking and flying seem out of the question.

"the extinction of the mammoth" -

That kind of skates through what occurred, as if that extinction was connected to gradual global climate change.

And which leaves out the simultaneous and instantaneous extinctions of mega-fauna that occurred world-wide.

I assume that the microblade knives were developed for fileting fish and preparing other marine foods.

And how exactly did Jacque's Bluefish Cave site "fall apart"?

The scapula was redated to the holocene.

Boats, on pages 48, 49, and 50 in Charles Lyell's Antiquity of Man (1863) he reports dugout canoes up to fifty feet long at Glasgow. I have not checked the dating, but I am sure they are Holocene. But thats not the point. During the late Pleistocene big trees in the northern latitudes were scarce if not at all, eg. Beringia or the Atlantic ice sheet. It would seem that a more sophisticated technology would be required and all we have for certain are bone needles.

Or, is there more, dannan14? [By the way, thank you.]

Farpoint wrote:The scapula was redated to the holocene.

Ok, it was a tibia, not a scapula. Since I erred, more information is required of me. The work of Cinq-Mars was excellent. However, a green worked tibia was dated to 27k RCYBP in 1973, making Bluefish potentially the oldest site. The tibia was redated to the late Holocene (Nelson 1986, Science Mag).

There were always issues with association of the lithics and the dateable material which makes the pollen data important in getting a handle on the timing of the occupation. The lithics are primarily associated with the transition to shrub tundra which means that the occupation occurred sometime after 13Ka caly;(Hoffecker and Elias, 2007).

My apologies.

Hi Farpoint -

Yes, palaeoclimate is always as constraint and indicator.
An excellent example you cite is the need for large trees for dugouts.
But in that case you also have to keep in mind hominid range with watercraft.

Another significant item to keep in mind is local micro-climates which may be far different than the surrounding climate.

In the case of Beringia, the ice free corridor to the south was open several times during the Pleistocene.

San Jon, the scale is in feet, compare to man's leg standing on the terrace.

Cactus Hill McAvoy 1996

Possible pine hearth 15,070 -+ 70 RCYBP

Clovis working surface 10,920-+ 250 RCYBP

They walked from where?

No problem...and considering this subject is about things dug out of the ground i feel secure saying that there will always be more

Anyway, just saw this today.

8k years still is not 13k or 30k or whatever and there is only a small fragment, but some evidence tends to trump none hehe.
