Irongiant97 Posted April 30, 2022 Share Posted April 30, 2022 Keewatin, MN, USA. Overburden pile from local iron mine. So I believe these to NOT be glacial erratics like my other fossils, which would be a first for me!!! Some obviously seem like clams of some sort, but what I stood out to me the most was the holes and subsequent worm-like things inside, most of which were loose enough to remove (albeit I broke most of them). My guess is they’re some kind of worms, any thoughts? Link to comment Share on other sites More sharing options...

Fossildude19 Posted April 30, 2022 Share Posted April 30, 2022 I think I see bivalves, and possibly orthocone cephalopods, rather than worms. 1 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Rockwood Posted April 30, 2022 Share Posted April 30, 2022 I may see what you are referring to now. The conical shapes may be nautiloid shells, but it's hard to tell for sure. 1 Link to comment Share on other sites More sharing options...
Rockwood Posted April 30, 2022 Share Posted April 30, 2022 The 30th photo may be a crinoid stem segment. 1 Link to comment Share on other sites More sharing options...

ClearLake Posted May 2, 2022 Share Posted May 2, 2022 First off, yes, they are fossils (or at least most of what you have shown are). There are several bivalves in here, especially the ones that look like this one: There might be a gastropod or two in there and then the cone shaped ones are probably orthoconic cephalopods as others have mentioned. I'm not that familiar with Minnesota geology and I guess I always figured as far north as you are in the state that you have predominantly very old rocks that did not retain much in the way of this type of fossils (especially in an iron mining area) so I think they are quite interesting. Maybe Mike @minnbuckeye can provide some better info and/or ID's. Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted May 2, 2022 Share Posted May 2, 2022 The long thin ones may be orthocone cephalopods, but there isn't enough detail in the photos that I can make out. There may not be enough detail in the fossils themselves to give a better ID. The brachiopods appear to be steinkerns (molds of the inside), which normally don't show enough detail to be identifiable. The long, thin fossils also look like internal molds, so precise IDs may not be possible. Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

minnbuckeye Posted May 2, 2022 Share Posted May 2, 2022 Maybe Mike @minnbuckeye can provide some better info and/or ID's. Unfortunately, I hunt the Ordovician of SE Minnesota. Cretaceous specimens from Keewatin, MN are far from what I know. Someone at Hill-Annex Mine State Park could likely ID your finds. Good luck!
