I found this walking a creek here in southwest ohio. Any opinions would be appreciated!

Wow, my first post on Tnet and I get a link to a cartoon! Really? Anyway, this rock is about the size of a junior football that's been flattened at one end and weighs 11lbs. It has what appears to be a crust and regmaglypts. It's also just slightly magnetic. I've been a rock hound since I was a very young boy and I have never come across anything like this.

If you really think you have a meteorite, take it to the geology professor at your local college or university. I have found a lot of L4-L5 chondrites, and my opinion is you have a terrestrial rock. Of course, ALL of my ex-wives would disagree with me - Good Luck!

Thanks Terry. It also sets my MD off, but I had to crank her all the way up. When i filed a small window and did the ceramic test it did not leave any kind of mark so i was thinking it might be an LL and was hoping for a variety of opinions before I take it somewhere. Thanks again

Post photo of filed window?

This does not appear to have a fusion crust, which is usually black or brown. Purpose of window is to get below the fusion crust, usually 1-2mm.

Looks kind of pointed though. May have regmaglympts. Ancient? Fusion crust would last for a couple of million years on earth.

I can't get a good pic of the window but its a lighter gray with metallic dots, not flakes. The crust also appears much darker in person than on film and I can actually flake it off with my finger nail in a couple of spots. If it is a chondrites it's definitely ancient.

Here are a couple more pics. It's hard to see the metallic dots but they are there.

Here are examples of L4 chondrites I have found at Gold Basin, in Arizona.
