Where'd you get that 1 inch cube from? It seems useful.

I received it from FF member @aerogrower he makes them. It is very useful.

Terrific finds, Ralph! :drool:

That orthocone is spectacular, and just look at all the brachiopods  lying around! :wub:

Does that large orthoconic cephalopod have bumps on its surface?  If so, very nice ornamentation!

 

I really like the strophomenid with all those inarticulate brachiopods on it - very cool!!!

I noticed that too - thought it was a bryozoan. Maybe it's coated in bryo's?

Admirable, whatever it is.

@Monica and @Wrangellian , I believe it is bryozoan- I will take a better pic later and post.

 

Here are a couple more quick pics that did not post last night. The first 2 are of the largest concentration of Isotelus parts that I ever found.

@Monica and @Wrangellian here are hopefully better pics. I am thinking bryozoan- it is The skinniest one I have ever found.

Beautiful. 

A species of Escharopora, perhaps?

Interesting.. The shape would lead you to believe it was a nautiloid coated in bryo, but were there bryos that grew in long spikes/pillars like that?

I don’t know that,  and I know @Tidgy's Dad responded- I will also tag @Peat Burns and @Herb .

We have a bumpy-looking bryozoan in the Georgian Bay Formation (Stigmatella) that I've found encrusting other fossils, including orthoconic nautiloids, but it's never looked as nice as the one that Ralph has found...

 

Here are pictures of mine:

@Nimravis - is there any evidence of a siphuncle at either end of your specimen?

But are they so evenly spaced? I guess bryozoa are space themselves evenly since they are in a colony, but I don’t know of any that look quite like that. But that doesn’t exclude the possibility.

I seem to recall a young artist from Israel who posted drawings of straight cephalopods on here based on descriptions in journal articles, but I can’t remember if any had bumps. Many ammonites have numerous tubercles so why not an otho covered in them?

 

It kind of makes me think of my polka dotted ammonites. Not exactly, but my polka dots are not bryozoan they go below the surface.

Oops, I think I totally missed the point of Adam’s post. It was the proposal that it could be a bryozoan rather than a cephalopod.

See Ralph, I can be a bit dingy. Why does it always seem to follow Adam’s comments though?

It's probably because I speak gibberish. :D

What Adam meant was "monticules".

Nim, some pretty nice finds you have there, congrats.

Picture from Dry Dredgers.

And one showing monticules (bumps) from an online retailer :

 

Ah! Didn't think they could get as big and round in x-section as Ralph's.

beautiful orthocone or whatever...never noticed anything even resembling such a piece at that location...but it is large and always interesting to explore.

looks like a bryozoa coated cephalopod to me also. Nice finds.
