Tube in rock ID?

Recommended Posts

Zenmaster6

Snow is just melting but in the mean time I've split open one of the larger rocks I took home and discovered a new little guy.
Probably a twig. If not it could be a tube worm. You can see brachiopods around on this rock, I do know it was a shallow Eocene ocean 50 million years ago.
So let me know what you all think. Maybe its just a stick or maybe something more interesting :)

Thanks for you time  - John

Sorry, I realized how far away these look after posting them. There is a close up.

Perhaps a bivalve. I often find modern razor clam shells with the valves still articulated.

A bivalve? Its very thin and slender. I've never seen a bivalve like this. Also this is smaller than a penny, couldn't be a razor clam.

Can you provide an end view---so we can see its cross section?

You are going to have to explain why not before I buy that argument.

Quantum tunneling from egg to adult ? or do juvenile forms look quite different ?

All of the photos are from the same angle.  :unsure: 

Maybe a few more pictures from different angles to give us an Idea of the shape of it from the top, or bottom?

Personally, I would try to remove some of the surrounding matrix, and see if it exposes something more definitive.

I have fossil bivalves that are much smaller.  :headscratch:

A bivalve can look like a centimeter long stick? I know about rudists being strange looking and still being bivalves but this is only 5x the width of a sewing needle.

I guess the size doesnt matter but its round like a marker, perfectly circular from the end. cylindrical.

That is why I asked for more photos from a different angle.  ;) 

4 photos from the same angle don't really help in determining what you have there.

Not sure this will rule mollusk out all together. Exposing an end as Tim suggests would be what I would try.

Scaphopod

That's what I was reaching for.

If this were indeed a bivalve I would be seriously surprised. Not because of the size (I've found bivalves that are pretty much microscopic), but simply because of the shape. This one really seems to have a bullet-shape, and I've never seen a bivalve like that.

Already more plausible in my eyes, but they are usually a little curved. This thing seems to be straight. I doubt it is scaphopod, but maybe keep it as a slight possibility (I don't wanna ditch that just yet). 

 

My first thought when seeing this was belemnite. But that wouldn't work if the sediment is indeed Eocene. How sure are you of that age? Where was this specimen found?
