No way to hit the center of that rock and create a concoidial fracture? Really? What happens when a piece of chert takes a direct hit? Not saying the rock isn't natural but a human could easily have done that. What breaks rocks naturally other than earthquakes and landslides?
For the closest match, you might want to try contacting people knowledgeable about your particular region, such as the Arizona Archaeological Society (www.azarchsoc.org) Verde Valley chapter or the Arizona State Historic Preservation Officer page (azstateparks.com/public-educationarchaeology-programs).
@@uwlmvac Big salute to you Is there an expert among you in this field because I want to communicate with him to advise me on some of the pieces that I have and I think that they are more than 200 million years old

One chip ,sets up an easy chip from the opposite side,,this spinning is ...what separates chimps from man ...a man with a plan....3(or 4) spins defines the plan and infers the man ...artifact!
Tell me Dr. what do you do when the Archeologist across our Ohio State are to afraid or to corrupt to Admit to a site ! Because of its State cover up & the site's size and Age ? Very Old , Very Large Covering Parts of 3 States , The standard B.S. archaeological line [a glacier did it] Not really sure how a Glacier actually makes Ceramics, Glass , stone work , Burials And a Documented Unresearched Mound Twice the Size of Monks Mound Cahokia ? I own a 1960's Intentionally Destroyed Covered over Burial ground in one valley and Part of the Ancient City on top of an End Moraine in another Valley ! To sum up how do we stop archaeological fraud ? Our gutless archaeologists are screwing upcoming archaeologist out of a job !

Awesome video ..as an arrowhead artifact hunter for over 36yrs these videos are outstanding information ! 👍
Thank you for this information, please don't stop putting up this information for the rest of us.
This confirms my guess about my rock that appears to have been repeatedly chipped to make tools. Thanks !
These are great educational videos. Thank you!
That was OUTSTANDING! Thank you for sharing!!
As old and used as some of these stones are do not always show the chips. Especially if found around rivers or creeks.
Alot of artifacts do not always show the napping.
Very good informative video on worked pieces. Thanks for sharing!
.Muy interesante su aportacion mi amiga ,.
Awesome video. You rock! 🪨

Wonderful, again!
Amazing content 🎉🎉🎉
Can I send pictures of my finds from Sedona?
What about art rather than tool?

Hey ara you’re a real nutcase aren’t you?
Ripple marks = concoidial fracture
If there's little to learn ,they don't dig it up...in 200 years they will have ..sharper scalpels
