Here is what I believe to be a concretion I found last year. Got a bunch of jokes about it being an old petrified cow patty lol. I was hesitant to open it up but I saw cut it the other day and was curious about what I’m looking at. There’s some cool veins in it, there is a “granite” like looking vein but not entirely sure what it is exactly. Then there is some like fools gold appearing metallic veins in it. Couple areas that look like some quartz or crystalline structure. Just posting to learn about it if anybody knows.
