Sam WP Posted April 2, 2023 Share Posted April 2, 2023 (edited) Wondering if you can help me identify these fossils. They are all on the same slab of shell rock in southern colorado, near lake pueblo. The two pieces that look like bone or exoskeleton (approx the length of an adult hand) are on one side and the round object is on the other. The third image is the side of the round object. I took it to show how deep it goes into the rock. There are many mollusk-type shell fossils in the area, but I've never seen fossils like these. Thanks so much for any help you can give.

Sam WP Posted April 2, 2023 Author Share Posted April 2, 2023 Sorry, should be more specific: this is in the United States in the southern part of Colorado near Lake Pueblo. Link to comment Share on other sites More sharing options...
Rockwood Posted April 2, 2023 Share Posted April 2, 2023 These are big flat mollusk shells. More specifically Inoceramid bivalves. 1 1 Link to comment Share on other sites More sharing options...
