Cluros Posted July 23, 2017 Share Posted July 23, 2017 Here is a paradox that was found at U-DIG while searching for trilobites. At first I thought pelecypod but as I started prepping I didn't find a shell. Instead I found it full of small cubes. I didn't take a pre-prep photo but I stopped prepping so you can see the shape and the gray surface. The white cube is one centimeter. Second photo.

Al Dente Posted July 23, 2017 Share Posted July 23, 2017 The small cubes were originally pyrite cubes that have been replaced, maybe with limonite. 2 Link to comment Share on other sites More sharing options...
Sagebrush Steve Posted July 23, 2017 Share Posted July 23, 2017 Could be the remnant of a Peronopsis cephalon? Link to comment Share on other sites More sharing options...
