deutscheben Posted September 18 Share Posted September 18 The calcite infill and lack of symmetry would lead me to identify this as a coprolite. 1 2 Link to post Share on other sites
Fossildude19 Posted September 18 Share Posted September 18 Better pictures in daylight, from directly above the item in question would be helpful. Oblique angles in a darker setting are not always the best for identification purposes. Also, please provide scale of the item, by placing a ruler in your photos. I think the lines are just from the way the concretion broke (conchoidal fractures) but better pictures would help tell the tale. Link to post Share on other sites
