Incense cone like teeth?

Recommended Posts

These are some things that look like an insense. On every one, there is a sharp rib as a tooth would have. Any ideas?

Do you mean incense?

Haha, yes that's what I mean. If your not old like me you, you probably won't get the reference,  lol.

I don't know how old you are, but I'm also not the youngest any more. I really am not sure what those things could be though. I was thinking belemnite, but the structure doesn't seem quite right.

They look like straight (orthoconic) cephalopods; note septa.

My goal is to leave no stone or fossil unturned.

Can we see photos of the base of the objects?

Theses are pics of the base of the 2 larger ones. There is a pic of a comparison with a typical Belamnite that we find. Unless there are different kinds, the Belamnite has a bullet shape, unlike the others.

I looked this up, and it does look like that. One question, wouldn't they be hollow?

Sort of like “nature abhors a vacuum”; nature abhors a hollow. Most hollows in fossils are now filled with sediment or minerals. If hollows are not filled then many fossils collapse if they are buried deeply. 

My goal is to leave no stone or fossil unturned.

They are definitely belemnite phragmacones. Very common find in the New Jersey brooks.

The age is Cretaceous, so not orthocone cephalopods.

I defer to local experts. It does look like a Belemnites.

@Fossildude19 What are the structures that look like septa? 
 

Also, I found a paper on an orthoconic cephalopod from the Eocene.

They are septa, just modified and reduced compared to the ones in nautiloids, the belemnite phragmacone is actually a very similar structure to those seen in nautiloids it's just that it was reduced and was on the inside of the animal rather than the outside.

Here is a diagram of the structures that make it up:

The larger item is the rostrum, the others are as others have said the phragmocone. This pic should help

Better photos almost always solve the problem. Belemnite phragmocone and/or rostrum tip was the very first thing I thought.

The dorsal ridge is characteristic of belemnitellid phragmocones and there's a corresponding groove on the inside of the alveolus. (Not to be confused with the ventral fissure which relates to the fissure under the ventral furrow on the rostrum - this is just in the rostrum and doesn't have a corresponding ridge on the phragmocone.)

 

(Belemnitella sp.. Maastrichtian, Belgium)

This is the right way up - groove corresponding to alveolar ridge at the top.

And fissure at the bottom:
