Another find from a beach at Lake  Champlain in Vermont that I originally thought to be just a cool rock but now I see it's a fossil of something, any ideas welcome!

I do not see anything diagnostic in this.

Look at the striations within the white part of the rock. 

[ynot]

I did, as far as I can tell they are not diagnostic of what this is beyond a fossil something.

Well then you have nothing constructive to add. Thanks for looking though.

Trying to say that some fossils are beyond recognition. 

Sorry if that does not help You.

I'm sorry if that came off as rude, not my intention. Of course your opinion is valued!

Detailed up-close photos of tops of the columns and the columns themselves might help for giving an ID. Are you able to take photos thru a magnifying lens? Silurian and Cambrian marine rocks are in the area. Possible candidates include: coral, bryozoan and sponge. A member with knowledge of the local fossils might be more helpful.

I think magnified is the only way this will be identified, I was thinking Bryozoa as a possibility. Unfortunately I don't have a way to take magnified pictures of good quality, but I will look into options. Thanks for the suggestions!

looks like a longitudinal  cross section of a horn coral

I can see that as well!

Horn corals are cone shaped. How does this object fit into a cone?

Crossed my mind the receptaculitid possibility.

The area does have a lot of material from the Ordovician, thanks for the idea!

Here is an article about receptaculitids. Note similarity between posted fossil and diagram of inflated hollow receptaculitid.

Jazfossilator, look for a geological map of the area to find the names and ages of the local fossil bearing formations. Look for marine units. Then use Google to search for fossils from those formations. For example: fossils from the x formation or receptaculitids (or other organism) from the x formation (or Vermont).

 

Even if you do not find what you are looking for you are guaranteed to learn about the paleontology and geology of the area.

Thank you! Knowledge is power haha, Vermont has some very old geological history, I think receptaculid is a good possibility though I can't find any examples quite like this

If you cut a horn coral at a 45 degree angle you can get an elliptical cross section . Just a possibility

Yes, but not a crescent moon shape, and there is no evidence of septia.

 

The original object is a small piece of the whole. It is thicker at the "center" than at the edge and shows no surface parts exposed.

The apparent structure could be biologic or recrystallized.

It could fit into many "classes", but there can be no certainty on what it is.

All of the suggested IDs are just guesses and any placement, other than shell piece, is an assumption.

Seems to me even striations can be used as diagnostic, if you look closely enough

I was thinking cross section of barnacle, but that may not fit the age of the rocks.

correct, just guesses

without more info it's a snarge shoot. Looks sort of like the Ordovician bryozoa/coral. Tetradium sp.

I plan to get magnified photos taken, I will post them when I do so everyone can have a look at the structure. Thank you for the suggestions!

[Jazfossilator]

Sorry to bring up an old thread, but do these photos shed some light on this piece?

[abyssunder]

In the newly posted pictures I can see a clockwise - counterclockwise intersecting rows pattern, so I think it might be a receptaculitid, something similar to Fisherites.
