rwise Posted March 18, 2015 Share Posted March 18, 2015 Found this in the TXI Cement Quarry in Midlothian, TX. It is 1.25 inches tall and about .5 inch at the base of the fossil. This is the ATCO contact between the Eagle Ford Shale and the Austin Chalk formations. Other finds in the area are Cretodus, Pytchodus, Squalicorax and other shark teeth, as well as fish verts. It has pyrite crystals up the middle of the fossil. Thanks for any help with ID Thanks for your help in advance. Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 18, 2015 Share Posted March 18, 2015 Looks fishy, to me. Maybe some locals will weigh in... Neat find.

Auspex Posted March 18, 2015 Share Posted March 18, 2015 I think it may be a mosasaur tooth that the pyrite has had its way with.

abyssunder Posted March 18, 2015 Share Posted March 18, 2015 ...may be mosasaur.I agree with Auspex.

TroyB Posted January 9, 2017 Share Posted January 9, 2017 Looks like a fossilized pyritized burrow to me. I have found several of those there at Martin Marietta cement quarry. Tankman Link to comment Share on other sites More sharing options...
rwise Posted January 9, 2017 Author Share Posted January 9, 2017 Not a burrow, too many linear features, i too find pyritized burrows there but this is different Thanks for your help in advance. Link to comment Share on other sites More sharing options...
Carl Posted January 10, 2017 Share Posted January 10, 2017 Could also be a weathered chunk of bone. The detail isn't convincing me it's a tooth. Link to comment Share on other sites More sharing options...
Vieira Posted January 10, 2017 Share Posted January 10, 2017 From the pictures i'm seeing, I don't see a tooth too. Post some more pictures please. A Picture of the root may help. Link to comment Share on other sites More sharing options...
TroyB Posted October 8, 2018 Share Posted October 8, 2018 Here is a 4" long burrow that filled in with pyrite from the Martin Marietta cement quarry, Midlothian Texas area. It has the linear striations as well. I still don't think it is a tooth, sorry. Looks like the bottom of a burrow to me. Tankman Link to comment Share on other sites More sharing options...
