Clovis Spurred Endscraper

[uniface]

Clovis (proper), as distinguished from presumably later fluted point people (Gainey, Barnes, Debert-Vail), made endscrapers with prominent, substantial spurs like these from Blackwater Draw:

This one, from Clark County, Ky. comes closer than any others I've encountered

Picturing this hornstone one (Dongala, probably, like the rest) ex Bill Tatu, ex Dick Savage, although it's as much cornered as spurred after re-sharpening, because, like the previous one, it shows evidence of the neutron bombardment of the "thermonuclear event" (Firestone & Topping) that brought Clovis to a fiery end. (Research paper -- extremely technical -- is in the Mammoth Trumpet and should still be accessible for free). Tap pictures twice to enlarge them enough to show this -- tiny pinholes. Not uncommon in some materials for geologic reasons but also diagnostic of neutron bombardment according to Bill Topping, who ID'd this in some artifacts I'd sent him to make sure I'd correctly identified what he wrote about.



Butt end end is thinned for hafting, as you'll notice. Not seen that often that I'm aware of.

This cornered endscraper shows the same thing (microscopic pin holing), but this may be normal for Sonora chert (?).

Some of these western Clovis scrapers have the spurs
and several also exhibit a thinning flake on the bulb.
