Need help IDing west Texas rock/fossil

[John R.]

This is my first time using the site, but my dad just purchased some property in west Texas next to big bend and i need help identifying a rock formation or fossil we have found out there. There are multiple so we were guessing it was a byproduct of the ancient volcanic activity or a fossil of sorts. it can be scratched by steel and there is barley any magnetic pull if any. please help id.

can't really tell, but it might be a concretion. I am not really seeing fossils, but I am kinda blind even with my glasses on. Harry where are you when we need ID?

 

[John R.]

Thank's for the mineral list very helpful info still not sure what it is, but now i know not to touch the Tyuyamunite!

I google search instead of going by the sample pictures they use since if you noticed they are almost perfect specimens

I am asking some members of a mineral club I am in..I posted a pic on that site as well..hoping for an answer for you soon.

Might not be but it looks like iron ore I find here in Ga

 

[TeAra]

I was told it looked like Almandine Garnet but I don't think it is...It looks more like Aragonite/Chalcedony which I saw was in your area..If so they say it is rare.

It's a type of Hematite, from what I can see.

Iron-hematite ore (kidney) hardnes 5.5-6

Going by the rusty colour I'd guess Limonite. A brownish streak?
