I've been sifting through a bucket of dirt I collected on my last dig in Cincinnati. I've come across these two pieces that has me scratching my head. Are they ammonites, snails, arms of a Isorophus?  Not the most glorious finds but two that I am having some trouble while cataloging. Thanks all! :):ammonite01:

They are both internal molds of snails (or maybe a monoplacophoran such as Cyrtolites for the one on the left).  They lack evidence of suture lines, the one on the right is coiled in a flattened turret shape (not planispiral), and the one on the left tapers too quickly, all features that exclude an ID as a nautiloid or ammonoid.  Perhaps you were joking about "arms of an Isorophus" but anyway these are never found as smooth internal molds, and your specimens lack the biserial calcitic plates of an edrioasteroid arm and are totally the wrong shape.

I was joking about the arms of an Isorophus! ... I just like the way it sounds hahaha (hence the bold letters) Thanks for your input. I really appreciate it.

:D Maybe we can make "arms of an Isorophus" a meme we can use for anything we can't identify!  I also like the way it sounds.  Could also be a name for a band.
