Bellerophon Gastropods in hash plates?

[Kato]

These are from the Middle Pennsylvanian (Beeman) in southern New Mexico.

 

60mm seam of limestone embedded with gastropods. So deeply embedded and oriented as to make identification more challenging.

 

Guess: Bellerophon

 

* Surface is not smooth.

* Appears to be symmetrical.

* Ridge along the midline.

 

Larger hash plate. Each of the larger gastropods is approximately 25mm.  This plate is 220mm x 270mm at widest measurements.

 

Smaller hash plate

It's my intent to prep on these two slabs while I hide from the heat during the hot months here in the desert. At least an approximate identification would be quite helpful so I have some idea of the shapes I will be trying to reveal.

Sorry not my area of knowledge.

Just wanted to say nice pieces, look forward to seeing them prepped.

Love the hash plates but these make it a little hard to see what you have. I would guess that these are probably Pharkidonotus sp.

We find two in Texas P. percarinatus and P. labioreflexus or it could be another species but this will give you some place to start.

I agree that they look like Bellerophon gastropods, or at least close relatives.

Definitely agree on the hard to see! If I cross that formation again maybe I'll get lucky enough to spot something more revealed. It's a long time until summer when I'll begin to start picking at it.
