PSchleis Posted January 21, 2019 Share Posted January 21, 2019 Found on Myrtle Beach. I've been picking up a lot of bone that is quite obvious to me in its look and texture, but this is a strange piece and I'm not convinced it's bone at all. The only reason I haven't given up on it is because it has two colors - the outside is black, the inside is brownish. Thoughts? Link to comment Share on other sites More sharing options...
ynot Posted January 21, 2019 Share Posted January 21, 2019 Not bone. Non fossil rock. Minerals in a rock can oxidize when exposed and make the surface a different color than the inside (in this case most likely an iron compound). 2 Darwin said: " Man sprang from monkeys."

Plax Posted January 21, 2019 Share Posted January 21, 2019 I would say it's a piece of either Peedee or Goose Creek Limestone that was a hardground at some point and got phosphatized (blackened). This can be seen in local quarries but seeing a piece in the surf makes it difficult to recognize. Rip up clasts in basal lags also get the blackened treatment and are often associated with vertebrate concentrations such as shark teeth. Link to comment Share on other sites More sharing options...
Rockwood Posted January 21, 2019 Share Posted January 21, 2019 I can't really identify anything, but I get a sense there may be fossils (marine invertebrates) in there. Link to comment Share on other sites More sharing options...
Rockwood Posted January 21, 2019 Share Posted January 21, 2019 Right there. Link to comment Share on other sites More sharing options...
Plax Posted January 21, 2019 Share Posted January 21, 2019 I agree with Rockwood. Giving it a wack with a hammer, if you should so decide, might expose some index fossils so we could ID the rock. Some small Anomia species are typical of the Peedee and Carolinapecten eboreas walkerensis is an index for the Goose Creek. Link to comment Share on other sites More sharing options...
