Darbi Posted August 10, 2020 Share Posted August 10, 2020 I'm wondering if it's a fossilized burrow or some form of ichnofossil. Notice the depression from the opposite side of the burrow-like projection. Dakota Sandstone formation and Cenomanian in age. Link to comment Share on other sites More sharing options...
Rockwood Posted August 10, 2020 Share Posted August 10, 2020 Looks like it would pass for half a hole. Link to comment Share on other sites More sharing options...
westcoast Posted August 10, 2020 Share Posted August 10, 2020 If the first image shows the piece the correct way up then burrow is most likely. Link to comment Share on other sites More sharing options...

I found it among the rubbles. Link to comment Share on other sites More sharing options...
