connorp Posted May 9, 2021 Share Posted May 9, 2021 This little bone chip is from the Dundee Limestone (Middle Devonian) of Ohio. I find a lot of bone fragments in these rocks, but this one seems different. In particular, along one edge there look like there might be serrations, so maybe a tooth fragment? It measures approximately 1cm at the largest dimension. Thanks for any input. Link to comment Share on other sites More sharing options...

jdp Posted May 10, 2021 Share Posted May 10, 2021 I don't think it's a tooth fragment. Could be a bit of placoderm armor though. I wonder if it's a piece of a gnathal plate. 2 Link to comment Share on other sites More sharing options...
