tfer Posted July 31, 2019 Share Posted July 31, 2019 Found this in 2012 somewhere in northwest Alabama, while tromping around. I've no idea what it is, but it looked like some kind of tooth in bone. The big protrusion looks rough and kind of like cement, but looking closer it appears to go into the "bone" area, like a regular tooth. I'm more of a rockhound, but this was too unusual to not pick up. Any help with identifying it would be greatly appreciated. Link to comment Share on other sites More sharing options...
FranzBernhard Posted July 31, 2019 Share Posted July 31, 2019 Welcome to TFF from Austria! Thanks for the many pics in different angles! The grey thing is a piece of oddly weathered limestone, definitely not a tooth. It seems, that it has some wavy lines in it, this could be stylolites. https://en.wikipedia.org/wiki/Stylolite I am unsure about the brown thing. It could be dolomite, a rather fresh siderite concretion or even chert. I am wondering, if there could be some organism involved forming its shape, because it seems that there is some spiraling pattern in some of the pics. But I really don´t know .

Ludwigia Posted July 31, 2019 Share Posted July 31, 2019 I agree with Franz. There is neither bone nor tooth there, but the spiral pattern makes it interesting. I'd say we need a trained geologist to help us here. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

westcoast Posted July 31, 2019 Share Posted July 31, 2019 Possibly a rhizocretion that has incorporated a piece of rock debris in soil. Link to comment Share on other sites More sharing options...
ynot Posted July 31, 2019 Share Posted July 31, 2019 I agree with the limestone and concretion ID, but wonder if the concretion could be a sponge also. Darwin said: " Man sprang from monkeys."

fifbrindacier Posted July 31, 2019 Share Posted July 31, 2019 Welcome from France. I agree the concretion might be a sponge.
