New find. Brachiopod ? or bivalve?


Rocky Stoner

Recommended Posts

This appears to be a section of the largest brachiopod or bivalve that I have seen here so far.

The ridges are near parallel in each direction and there is a very slight arc to the surface suggesting (to me) a relatively large specimen.

I did not see it in the link referenced earlier.

Does anyone recognize this one ?

 

The next post has a stranger in it as well. Almost looks like the hinge of a brachiopod, but not sure.

 

Thanks again.

Possibly a flattened piece of an orthocone nautiloid with longitudinal ridges?

And a brachiopod.

The second one is a brachiopod hinge.

First one is hard to tell, but my guess knowing these rocks is likely some type of chonetid brachiopod.

 

The second is part of a spiriferid brachiopod, likely a Mucrospirifer mucronatus or maybe Spynocirtia sp. (I think that's the name of the other one).
