Unifaces II & III

Unifaces II & III

The black one (black Buffalo River chert, unless I miss my guess) fits right into a type that thirty7 and I are working on trying to define. Core-&-Blade technology and large size place these in the Early Paleo (Clovis) era.

Re: Unifaces II & III

Nice, those are much larger than I was expecting from the lot picture you posted the other day. The size alone suggests paleo horizon. I'm well aware all cultures manufactured uniface flake tools and knives, but out of the 40 or so Hopewell uniface pieces I have, none exceed 2 inches in length. Not saying this proves anything, just playing the averages here.

Re: Unifaces II & III

Ok so it is the small edge work that defines that piece? The small micro pecking or is it pressure flaking. The reason I ask is that looks like a common tool scaper any of us might find or even pass up as debri till you came along. I am seeing the large random flakes that reduced the item then very small almost like serrations on the edges?

JMO... If I found that in a creek. I would say it was raw flint that has been creek tumbled.. I find alot of stuff like that, here in my kneck of the woods. Just my opinion. John

In the second one, note : four North-South removals ; one South-North removal, then a North-South that detached the blade.

The first one is similar, but less immediately obvious.

What isn't apparent in the pictures is the thinness of them :

Re: Unifaces II & III

Those are some beautiful examples, and I agree very different than Hopewell Bladelets.

Here are a couple examples that I have pictures of on my laptop. These are all from Mexico, and probably not more than 2000 years old; the Obsidian rich areas of Central Mexico, Guatemala and El Salvador took core blade technology to extremes. I've seen examples much larger than this one. The other ones are the the smaller, more refined core blades. And pictures of both types of core (the really large cores weigh up 40 or 50 pounds, and no one thought to bring any back prior to the ban.)

The key differences between this technology and Clovis is the thickness/regularity. There are two types of pre-colombian core blades, the more refined ones are thin enough to be Paleo but way too perfectly regular, the other is more irregular but way to thick to be paleo.

Re: Unifaces II & III

Woah, Joshua, that is one monster uniface blade, nice bladelets too.


Both of unifaces pieces look like a match for clovis blade tools imo.

the last paragraph here explains clovis blade / core technology a bit

notice the consistency in edgewear.
