New Members Noah Loiselle Posted March 3, 2022 New Members Share Posted March 3, 2022 Hello all! I was wondering if anyone would perhaps be able to help me identify this species of cephalopod I found last summer while out exploring for fossils on Manitoulin Island in Canada (specifically in the Sheguiandah area)? I am pretty sure it is some sort of Orthocone, but it would be neat if I could narrow it down to a potential species level for sure. Any help with this is greatly appreciated!

Fossildude19 Posted March 3, 2022 Share Posted March 3, 2022 Welcome to the Forum. Your pictures are much too small to make out any detail. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

Kane Posted March 3, 2022 Share Posted March 3, 2022 Agreed -- larger photo will help with determination. The Sheguiandah area is mostly Lindsay/Cobourg Fm dolostones, with some surge channel grainstones. We can at least narrow this down to Upper Ordovician so far. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
New Members Noah Loiselle Posted March 3, 2022 Author New Members Share Posted March 3, 2022 I kind of though they would be. I will see if I can get some more high quality photos and upload them as soon as I can! Link to comment Share on other sites More sharing options...
New Members Noah Loiselle Posted March 4, 2022 Author New Members Share Posted March 4, 2022 I hope these are better (same fossil from various angles). 1 Link to comment Share on other sites More sharing options...
New Members Noah Loiselle Posted March 4, 2022 Author New Members Share Posted March 4, 2022 (edited) I also have this one that is similar (although it seems to be slightly flatter, but that might just be due to the fossilization process).

Thomas.Dodson Posted March 4, 2022 Share Posted March 4, 2022 Spyroceras bilineatum? Do you know the specific formations or age exposed in the area? 1 Link to comment Share on other sites More sharing options...
FossilDAWG Posted March 4, 2022 Share Posted March 4, 2022 The combination of ribs and prominent longitudinal striations also suggests Gorbyoceras as a possibility. Don 2 Link to comment Share on other sites More sharing options...
