$Lynn$ 3 Posted February 13 So my grandson and I were collecting rocks from my land in N.E. Oklahoma around chelsea okla. I found these elongated rocks with what looks like a rock growth on them. they are brittle I dropped one and it broke with ease. You can see in pic the center of the broken one. If you tap them together while loading they sound metallic ish. they are seemingly heavy. smooth but in places looks like a growth. The growth is as hard as rock itself. Thanks ahead for your help. the first pic is the broken one. its mate is in the forground. Quote Share this post Link to post Share on other sites
bigrex 52 Posted February 14 Looks potentially sedimentary, not sure of much else. Quote Share this post Link to post Share on other sites
Morlock 1,023 Posted February 14 Limestone perhaps? Put a few drops of warm vinegar on it. If it fizzes after a few minutes, it's limestone. Quote Share this post Link to post Share on other sites
4meter 158 Posted February 14 I agree with Morlock. Looks like a fossiliferous limestone that is weathering unevenly due to different difference in the material that makes up the rock. Quote Share this post Link to post Share on other sites

chrisski 622 Posted February 14 Are they typical of the rocks found in that area? To me it kind of looks like what someone may have used as an old cobble sidewalk. If there's lots of those spread all over, I doubt it, if they were found in one group, maybe. Quote Share this post Link to post Share on other sites
