I can usually find at least a close cousin to what I find to lead me in the right direction... I am lost when it comes to these...


(In reference to the photos below, I apologize for not explaining more when I posted.. I am new to this Smiley  Sorry for that.

The first three pics are different angles (front and back) of the same stone.

The next two pics are the same stone, one a closer shot. ~~   to me is an amazing color - lI love anything blingy lol

This also is the same specimen, front and back pic
The last piece I was pushed more into believing this is a fossil of some sort of marine life as well.  It immediately made me think of a clam or something of that type but someone told me that rolled up trilobites look oddly like that also  Huh

Good selection of ROCKS there, naturerocz!
Given where these rocks come from I would venture to guess we are looking at several varieties of sedimentary rocks, and some pressure.

The first one looks like it was trying to be a vein agate but didn't quite make it and are left with silica that looks like quartzite, but maybe not enough pressure to relly call it quartzite either. Huh
But it does have those interesting dark bands or rings swirling thru it.
Try this link to help explain those,https://en.wikipedia.org/wiki/Liesegang_rings_(geology)

I'm going to guess the rest of your rocks are different forms of chert. There may be a local name for the middle one if there is enough of it in the area to make it identifiable. If so, then it could be a local knapping material. I wonder if any of your husbands artifacts are made from it, or something similar? The last two look like the chert was either formed among marine fossils, to explain shapes, or the chert actually replaced the fossils, last one.

Best guesses for today. Hope it helps!
