I am no geologist but if it is magnetic and your sure it wasn't found in a foundry. I think it could be a meteor core. Such as this:

Meteorites are usually heavy, contain a lot of iron, and others are light and contain no metal.
Meteorites form a fusion coating, a thin layer of dark glass. The fusion coating may be black or brown, dull or shiny on a recently fallen meteorite. The fusion coating may even rust, giving the outside of the meteorite a reddish-brown coloring, or the fusion coating may erode off partially or completely.

My advice would be to take it to a local university. They could tell you for sure.

I forgot to put its not magnetic it is heavy.

Its a contaminated meteorite. What you have here is the cause of the next zombie invasions. Im suggestion is leave it where it is and make a run for it. Its to late for your home town. It's now ground Zero.

Zombie meteor? I think that is the next movie title on the SyFy channel.

If that is soft metal like lead it could be just a blob of lead that somebody melted down. Lead melts at a pretty low temp I have melted it on the stove in a cooking pot before. How big is it? Looks kind of small from the photos. So if you live near fishing pond or lake it could be a fishing weight.

Yea i thought lead also but i took my knife to the rock it will not shave any off or even scratch the rock its hard. The weird part is my family and I was working cows and found it in there feed trough. The rock is little bigger then a 2 liter bottle cap

So, it's not deforming, not magnetic but still it looks like kind of a metal? I'm quite sure you got an extraterrestial super-rare new kind of metal you can sell to the NASA or such for quite some money

No, seriously, take it to the nearest university or a friend of the family who knows about geological stuff. But don't you give it away! Or if you do, let them hand you a paper that they're only testing it for you and that you're the owner. Might be over-cautios, but maybe it's really some kind of rare metal you can sell for a few bucks.

Oh, wow! Drunkjedi, you found my bath sponge. Still got a couple of years use left in it, I reck'n!

I think it's just flintstone with porphyry in it.

That explains it, your cows are playing a practical joke on you. I can see them now,

"Look here they come. Quick put that funny looking rock in there."
"Why?"
"The big monkey will get all puzzled about it and start posting images to his facebook."
"Ha ha ha..."

The surface looks a lot like Galena, however Galena's crystal structure is most commonly cubic or octahedral. Your specimen has no visible crystal structure at all.
If you really want to figure out what it is, you could do a water displacement test on it. Galena is about 7 1/2 times heavier than water.
If this really is Galena, it should mark pretty good (almost like charcoal). You wouldn't want to get it on your hands, and then put them in your mouth as the stuff is Lead Sulfide (PbS).

One more thing, I looked up the common occurrences of Galena, and it appears they find a lot of it in Oklahoma in their lead/zinc mines. So that might be where it came from.

P.S. Technically, it's not a rock, but a mineral. A rock is a composition of many different things. A mineral has a single chemical compound throughout. I'll shutup now. :lol:

[edit, I didn't see your lead comment. If it's that hard, it pretty much rules out Galena. PbS is about 2-3 on the Mohs scale I believe (softer than a copper penny)]

It's quite hard to distinguish any microstructure with a naked eye.

No no ! You were starting to make a lesser moron of me lol !
7 times more dense than water you say ?
Far from a black hole but pretty close to a very cool apparatus to keep.

no wait,
I am wrong,
this is useless
you don't want it.
just send it to me and il pay for the shipping fees.

Take some new pics next to a quarter and pop it up on eBay or Craigslist. Don't give any description other than "A rock I found while tending my cows. Buyer pays for shipping."

People will buy anything. :lol:

But seriously, I wanted to know if you live near a river? It looks like something smoothed over time by a constant water flow.

Denser as in heavier.

whut ?
If you're not talking about density what are you talking about

Hardness ?
