Iowa/Minnesota Orthocones (Ordovician)


Wrangellian

Recommended Posts

Mike @minnbuckeye kindly sent me a package of orthocone nautiloids from his area recently. It's one of the taxa that are sparse in my collection so I was happy to accept the offer. I'm posting them to show what a generous guy he is and to elicit more info about them that might be missing...  I don't think that big one in the lower right was labeled - Is it the same as the other large one, Elgin IA?

Those are some good looking orthocones!

Orthocones :yay-smiley-1:

As long as it is a paleozoic cephalopod you got my attention :P

growing old is mandatory but growing up is optional.

I'd be happy with those! Especially the Isorthoceras sociale.

Now I remember what I sent you!! The unlabeled one is from a housing development in Rochester, Minnesota, Olmsted County. Likely from the Platteville formation, Ordovician.
