Brandy Cole Posted February 26, 2023 Share Posted February 26, 2023 From time to time, I find these rocks in the river that look like they have many small shells and fragments embedded in them. Unfortunately, mostly what I know is Pleistocene, so it's hard for me to make anything out of them. This one I found a couple of weeks ago seemed particularly busy. Would love it if someone could tell me more. @JohnJ @Jared C Link to comment Share on other sites More sharing options...

Rockwood Posted February 26, 2023 Share Posted February 26, 2023 That must be Cretaceous. There are a few small gastropods in there. The Z shapes and cogs, I have to wonder if the Texas rule applies. 1 Link to comment Share on other sites More sharing options...
Jared C Posted February 26, 2023 Share Posted February 26, 2023 IMO, that reminds me of the conglomerates from the sparse Eocene Claiborne group marine deposits on the river. Whiskey bridge has boulders of these. If you can follow those and sniff out an outcrop that isn't at the bridge, you'll have something special on your hands 1 1 “Not only is the universe stranger than we think, it is stranger than we can think” -Werner Heisenberg Link to comment Share on other sites More sharing options...
JohnJ Posted February 26, 2023 Share Posted February 26, 2023 I agree with Jared. These look like tumbled Eocene shell matrix. It's amazing how far things make it down the river. 2 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
