New Members AnneHall Posted July 3 New Members Share Posted July 3 Are these fossils? Or rocks? I find clams (seen in one photo), bivalves and other castings all over the ranch. These are fragile and break horizontally. Link to comment Share on other sites More sharing options...
debivort Posted July 3 Share Posted July 3 I think you might have infilled burrows (trace fossils). The lower item in the last photo looks like a bivalve shell to me. There are TX experts here. Cretaceous marine formations are exposed in the Hill Country, so perhaps that's what you're seeing. Link to comment Share on other sites More sharing options...
