Bev Posted July 29, 2013 Share Posted July 29, 2013 Ordovician. Galena Formation probably. Found on rocky beach on the Root River. SE MN. To me, the totally untrained eye, these look similar. To me, they look like leaves. But I know nothing. Thoughts? Ideas? Speculation? Mother Nature playing with me again? Too water worn to make out anything? Thanks for looking!

squalicorax Posted July 29, 2013 Share Posted July 29, 2013 The second one looks cephalopod like. My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...
Bev Posted July 29, 2013 Author Share Posted July 29, 2013 Really! I should note that both of these are about the size of my palm. I just didn't see cephalopod coming!

Caleb Posted July 29, 2013 Share Posted July 29, 2013 Looks like burrows/trace fossils in the first and a cephalopod in the second picture. Caleb Midwestpaleo.com Link to comment Share on other sites More sharing options...
Indy Posted July 29, 2013 Share Posted July 29, 2013 Bev When you're hunting river localities ... You probably will find fossils from other time periods even if the general area is Ordovician.

Caleb Posted July 29, 2013 Share Posted July 29, 2013 The root river cuts through pretty much the entire Ordovician section. It starts in the Ordovician Maquoketa Formation near Spring Valley and ends up in the Cambrian at the Mississippi River. Being that the rock looks to be limestone places them probably in the Ordovician, but nailing down a formation would be very difficult. 1 Caleb Midwestpaleo.com Link to comment Share on other sites More sharing options...
