Collin Posted June 16, 2018 Share Posted June 16, 2018 This was found in a pile of old stones near my home (countryside of western New York State not that far from the shores of Lake Ontario.) the rocks were delivered to put down in a stone driveway and I happened to stumble across this a year or so ago. I would love to know what it is/was. Link to comment Share on other sites More sharing options...
Rockwood Posted June 16, 2018 Share Posted June 16, 2018 Mold of a crinoid columnal known as a nodal. The small circle is where a cirrus was attached. Link to comment Share on other sites More sharing options...
Innocentx Posted June 16, 2018 Share Posted June 16, 2018 The curved lines are your fossil... might be a mollusk although there's a tooth shape going on here. There's not a whole lot to go on. This rock would definitely catch my eye and go in the pocket. The circular inclusion? adds interest, as well. Very nice. Welcome to TFF.

Auspex Posted June 16, 2018 Share Posted June 16, 2018 I am having trouble gauging the size of it. Also, I am curious about the void I can see at the top edge in the second picture.

I've not seen crinoid shapes with a curvature in section like that so I'm gonna throw this out as a possibility... My mind wants to shear a section showing a couple septa from an orthocone nautiloid at an angle to expose the siphuncle which would produce that circular feature......but my brain gets way overzealous admittedly and that organic tea I just started taking aint helping....... An example from another fossil forum post. Maybe? Regards, Chris Link to comment Share on other sites More sharing options...
BobWill Posted June 17, 2018 Share Posted June 17, 2018 Welcome to the forum. That's an interesting piece but there just may not be enough visible for a good ID. The rock looks very hard but if not maybe you can chisel some of the matrix away for a better look. Can anyone tell us how old something from that area might be? 1 Link to comment Share on other sites More sharing options...

Orthocone did occur to me as well. It's a little hard to determine which surface is which from the angle it is exposed. Link to comment Share on other sites More sharing options...
abyssunder Posted June 17, 2018 Share Posted June 17, 2018 I'm also having trouble identifying it, because I don't know where it came from, it hasn't a comparative scale beside, there's only one side shown, and the specimen is partially embedded in the matrix. What is sure, is that the matrix is a pebble (or cobble), rounded on all sides, which indicate it was naturally transported material by rivers or glaciers before it was transported and deposited in the location where it was found. I think, there are also other possibilities along the ones suggested before, like anellid / serpulid worm tube(s), rudist(s), or something else. Hard to say with certainty in an equation with too many unknowns. My guess could be worm tube(s), but it's just a guess. picture from here " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Rockwood Posted June 17, 2018 Share Posted June 17, 2018 Articulating facets of the adjacent internodal ? As support for my theory. The axis would be from the upper left corner of the photo running to the lower right of the viewer. Link to comment Share on other sites More sharing options...
