Geological or Orthocone cast

Recommended Posts

Kato

Hi, noone will hurt my feelings if this turns out to be geological and not an orthocone cast. I was exploring for other fossils when I chanced upon 3 separate specimens of the following. They were all about the same dimensions and appearance so I decided to bring one home. What the heck it only weighed a couple of pounds.

 

7.5" x 3" at the widest. Elliptical shape on left end

Yes, i'm fairly certain that's a section from an orthoconic nautiloid.

Nice find!:)

Agreed.

Suppose the sponginess is preserved cameral  deposit, maybe even indicating the ventral side ?

Thank you for the confirmation. Part of me was wanting it to be a concretion as I am too easily distracted by all the wonders out there. 

 

What with finding 3 in a small span of time and a small area, I now sort of feel like I need to go back and try to find a really nice complete specimen. 

 

Thanks again!

I didn't notice the weight.

I think it may be preserved within (with, by, whatever) a stromatoporoid.
