Great finds, Mark - congrats to you and your wife!

 

Do you think the large cephalopod chunk could be a piece of Endoceras?  I think they can be found throughout Ontario's Ordovician rock, including the Georgian Bay Formation.

Interesting thought! I imagined that genus to have rings with slight concavities, or a little dip in the middle. Basing this on the Gull River rocks, and on Alice E. Wilson's Ottawa area catalogue. But I am shakey on IDs, so it is a promising possibility.

 

Thanks for the tip.

 

P.S. Wonder why Hessin is so cursory about Georgian Bay formation? Seems not to have photos of many of our types.

I can't be sure, but I imagine his book focuses on where he personally collected most of the time, and since I think he's from the Cobourg area, perhaps he focused more on the fauna found in the rocks further east of us.  Just a thought. :)
