What could this be?

[Phishmi]

If you have any clue what this could be, please let me know . Found in Michigan, in our creek buried in sand. I thought it was a bone. I see a hole, then something more inside the hole. I tried posting the best pictures. There is one picture that I got the rock wet. It also looks reddish? Thank you.

Welcome the forum!

 

i have no idea what you have but it's certainly interesting. Can we have more images from other angles? Have you wet the rock in the second imag?

[Phishmi]

First Picture Dry .. Second picture Wet ?Third picture (One I just posted)different angle, but it's not as good of picture as the others.

I'm getting a nautilus vibe, but not my area of expertise. Best wait for the experts!

[caldigger]

I too am on the nautaloid train, pretty cool for Michigan.

[fossilized6s]

I'm in the nautilus camp as well. Neat piece.

I agree - it's a cross section through a nautiloid, or goniatite. 

Great find.  Thanks for posting it.

Looks like a Goniatite fragment. Likely Mississippian.

I agree with nautiloid also. nice find

[doushantuo]

goniatite,given the suture line

(e.g.)

Tornoceratid?

[Phishmi]

Silly question .. is this the whole thing or just a piece? 

[Yvie]

Just a piece showing cross section of the chambers

[TqB]

I agree with goniatite.

[Carl]

I'm with goniatite. Nautiloid sutures wouldn't be so wavy (I think). Excellent find!

Maybe this document helps a little in the ID: A. K. Miller, H. F. Garner. Lower Mississippian cephalopods of Michigan. Contributions from the Museum of Paleontology University of Michigan. Vol. XII, No. 8, pp. 113-173

Thank you so much for all the information. I of course have more questions. This maybe confusing, . But in the first picture, I see what looks like little red lines ,And a little circle with red lines it looks kinda like a sun. (On the right) ,i know absolutely nothing about these. Does this mean there is more inside? .. thanks again 

[abyssunder]

Maybe I'm wrong, but some parts could be embedded in the matrix. Try to compare it with Imitoceras rotatorium.

 

 

 

 

[Aurelius]

Yes - imagine a goniatite, as seen in the picture abyssunder posted, sliced right through the middle, into two identical halves. That's probably what you have.  It's possible that some of the chambers are filled with that smooth rock (perhaps calcite) and the rest are filled with the same coarse matrix which surrounds the fossil, which is why it's not as clear as it might be.

Nice one, congratulations.
