Tightly coiled cyrtoconic nautiloid found in Middle Ordovician Deschambault formation (Trenton Group), Canada.

Hey there guys.

 

First of all, I would like to deeply apologize for the potato phone, over exposed, shaky, early Blackberry quality of the picture. This is not what I am used to post here on TFF and I am somewhat ashamed of this footage. I took the picture late at night and did not verify the image quality before leaving the site, which is far away from home. I will acknowledge and accept every insult sent towards me for this rookie mistake. Help me God.

 

But there it is. We were at the end of a rope climbing course in Portneuf county, Québec province, Canada; when we stumbled upon a well preserved tightly cyrtoconic nautiloid cephalopod. The fossil was found in the Middle Ordovician Deschambault limestone formation (Trenton Group), on a horizontal limestone bed by a small river. The specimen in 10 centimeters across (10x10 cm, or 10 cm diameter).  Chambers and septas could clearly be observed in the shell (even on the terrible/punishable by prison picture), but not the siphuncle. 

 

 

Since this is the first cyrtoconic nautiloid I find in this area, I would like to read your educated guesses on which Order or Family this nautiloid could belong to. After a short chat with OpenAI, we narrowed it down to a possible Tarphycerida, but I'd like to read you guys instead since human experience and judgment is much more reliable that actual AI.

 

What Order/Family do you think it belongs to?

 

Thank you very much.

A clearer picture that shows detail, would help to get a more accurate ID.

With this pronounced blur, I imagine you swinging from a rope of 30 m in a strong wind !

 

Sorry, I can’t help you.

The hardest part was clicking the camera button right in time when the rope swung across the fossil. GOT IT.

Better, in focus pictures are needed to be able to say anything intelligent about this.

About all that can be said is that it could be one of the Tarphyceridae.

AI is quite terrible for identifying fossils.     The technology just isn't there yet.

 

Take anything that AI told you, and toss it out the window.

Apologies don't help in this case. I guess you need to climb back up there to get a better focussed photo.
