Tony G. Posted October 1, 2016 Share Posted October 1, 2016 I was wondering if someone familiar with Eagle Ford fossils from the Las Colinas, Texas area could identify this. I think it looks like Inoceramus, but am not sure. For size reference, the graph paper that it is sitting on is 1/4" grid. Link to comment Share on other sites More sharing options...
Ludwigia Posted October 1, 2016 Share Posted October 1, 2016 I'm not familiar with Eagle Ford fossils, but that certainly does look like an Inoceramus. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
abyssunder Posted October 1, 2016 Share Posted October 1, 2016 I think, Roger is right, also you. Could be an inoceramid valve. The general shape is good for that, also other details. I'll attach here an image with some features regarding to the morphology of inoceramid shells, compared with your specimen. I think, that the evolution characters from the juvenile stage to the adult stage are distinguishable in the specimen in question. Ireneusz Piotr Walaszczyk.

Ridgehiker Posted October 2, 2016 Share Posted October 2, 2016 Re Inoceramus. I've always found this bivalve a bit of a puzzle. Hard sometimes to get a handle on the shape...especially as the two shells are often offset. Even in the same deposit they would confuse me as I didnt know there were juvenile and adult stages in their shape. Link to comment Share on other sites More sharing options...
