Unknown Fossil Needs ID

[TPryan]

Found this slab of limestone digging out an old garden wall. I think it’s a large plant or small tree, approximately 15 inches long and 3-4 inches across. Not much detail visible in either end.
 

Any help?

[Tidgy's Dad]

Hmmm.

Could we see the ends anyway, please?

I think that could be an orrthoconic nautiloid.

Definitely an orthoconic nautiloid.  You can clearly see the chambers.

Othocone nautiloid for me.

[Mark Kmiecik]

Orthocone nautiloid as the others have mentioned. I just wanted to say, Nice find!!!

[TPryan]

Thanks for the ID - I had no idea. I’ve heard of nautiloids, but not straight ones. I think we found another one today!

 

I’ll post additional pictures soon, including the ends.

Looks like a lovely nautiloid to me. Where exactly did you find it?
