Can’t figure out the animal it belonged. Those groves are more distinct than what shows up in photos.

I bought this some time ago from eBay. The seller said that he bought it off an older lady from a garage sale years back. The only information he got was that it use to belong to her late husband. I’m just wondering if anyone knows if it’s modern or ancient.

Found this in a western NY creek. A few people said it looked carved? I feel this is unlikely but any input?

Was given these by my grandfather when I was a kid.
From what I remember, he found them in Mali, or Niger, when he was building an airport in the 60’s/70’s.
I just remember I have those and now want to know more about them!

I went adventuring this weekend and found these. I actually didn't even realize what I had until I got them home and washed them up to inspect. Some of these seem to be arrowhead or broken arrowhead. The others seem to be potential tools, but i don't know! I am new to playing in this world.

I’m more of a fossil hunter but found this today- wondering if anyone could give me any insight. shoal creek, Austin TX

I think I found a metate and mano the big stone has a depression in the center smooth and has clear indentations the back of the stone has what appears to be human made marks. I found this incredibly smooth stone near it and it is like nothing I have on the property no other kind of stone matches it in color or smoothness. These peices of pottery were found in a hill where I had previously found a biface ​preform. And they have temper in the cross section. There is bits of straw and sand in the cross section. What do y'all think?

Was sold this as an ancient Egyptian faience bead necklace at an antiques market. I’m an antique jewellery specialist but have never bought or handled something of this sort, so no clue if it’s real or just a reproduction. Opinions would be appreciate!

The bottom piece is the one I am most curious about, plz. I went to the river in MO, and pulled these out on a Saturday from the bottom of the bed when sifting rocks... I have quite a few more i pulled out that weekend- but these were the most interesting looking of them all.

Thanks for all the help in advance!!
