DinoMike Posted November 16, 2015 Share Posted November 16, 2015 I found this object partially visible in a chunk of matrix from the Martin Marietta quarry near Midlothian, Texas. (Formerly the TXI quarry.) The site is listed as being basal Atco contact between the Eagle Ford shale & the Austin Chalk. The rock I found this in was Eagle Ford shale. At first I thought it might be a tooth, but on-site tentative ID was possibly brachiopod, but as the ends were buried in matrix, no one could be sure. I do note a "ridge" down one side that LOOKS almost like the worn serrated edge of a tooth, but the broken end of the piece doesn't look like tooth structure.

FossilDAWG Posted November 16, 2015 Share Posted November 16, 2015 I'll tentatively suggest a phosphatic internal mold of a finger of a crab claw. Don Link to comment Share on other sites More sharing options...
DinoMike Posted November 16, 2015 Author Share Posted November 16, 2015 I'll tentatively suggest a phosphatic internal mold of a finger of a crab claw. Don .. you know, that never occurred to me. Looking at the piece now, it does seem very crab-like. If that's what it is, that would be awesome. I've never found any crab fossils! Link to comment Share on other sites More sharing options...
