Johnny676767 Posted March 28, 2020 Share Posted March 28, 2020 Hello, my son and I had a great time on the shores of the Potomac River in Maryland, USA yesterday. Found some nice shark teeth and also a few objects that may or not not be fossils. We’re hoping you could help. These two pieces were associated with the Paleocene Aquia formation 56-59 million years old. Here are 4 pictures of each of the two objects. #1 #2 Link to comment Share on other sites More sharing options...
Rockwood Posted March 28, 2020 Share Posted March 28, 2020 I think these are a form of ironstone concretion. I've seen them referred to as "doo dads". Could have been @Carl I got that from. Link to comment Share on other sites More sharing options...
