I found this walking in Vermilion County, Illinois a few years ago. This was in a corn field by my house. It appears to have been used for something and I thought it was unique so I took it home. I’ve been keeping it up by my house for a few years now and decided I’d like to try and identify it possibly. I’ve been looking online and to me it looks like an Native American flaked axe or possibly something else used by them. The indentations on it are very unique. Open to suggestions please. Thanks!

Yell County , Arkansas

Keewatin, MN, USA. Overburden pile from local iron mine. So I believe these to NOT be glacial erratics like my other fossils, which would be a first for me!!! Some obviously seem like clams of some sort, but what I stood out to me the most was the holes and subsequent worm-like things inside, most of which were loose enough to remove (albeit I broke most of them). My guess is they’re some kind of worms, any thoughts?

So I went to a new site nearby me where I heard there were shark teeth and while I didn't find any shark teeth I found flint(?) fossils, that, unlike my previous flint(?) fossils, which I believe were deposited by glaciers, I think these ones are native to where I found them, which is an old mine overburden pile (the rock above the ore they're mining for), my evidence for this was the presence of many iron rich rocks that was in the same pile, pictured I have what I believe is botryoidal hematite, which hematite is what they mine here. Also the fossils in these new specimens are different to my glacial ones, which mostly have crinoid stems and brachiopods, here I've got spiral shells and other clams. Also they're much bigger and in much better shape. The Coleraine formation (cretaceous) runs just south of where I live according to a bedrock map, and another nearby mine tapped into it years ago (Hill Annex) and is fossil ferric, the bed rock map shows it doesn't quite reach the mine I live next to, but I'm doubting the map is perfectly accurate since the mine I live next to has dug up sharks teeth, fish vertebra, and saw fish saw teeth. (MN Discovery Center has some on display). Anyway, any help identifying these and what possible time period? I really hope they're native fossils and not glacial.

This is a rock/fossil found in grandparents rock bed. I believe it to be a fossilised lizard on top of a rock. When I studied it, I noticed the lizard shape and, on the bottom side, what seemed to be an engraving that looked interesting. I tried to write down the symbols I saw and research them and came up with something similar to the Mayan writing for lizard. Looking for any advice/input on this intriguing piece.
