Nuculites oblongatus

I am not seeing a fold in there,

I just found another part of the animal, here's what it looks like now:

Now that I can see the hinge line better, I agree with your initial ID 100%. Nice to have both pieces to make the shell whole. :)

Thanks for the help Dave,

It was definitely a nice surprise to find the other part of the shell in my pile of matrix.

As I continue weathering shale from PD, I have found a new mystery, I think this is a gastropod but I am not sure of genus or species,

Maybe @Fossildude19 or @Shamalama can tell me about it?

Thank you very much.

Looks like a small Platyceras or Nanticonema type gastropod. What is the scale?  Is it planispiral (coil is overlaps but stays flat as shell increases in size) or conispiral (coil overlaps on an angle and forms a cone shape)?

I agree with Dave. 

I would go with Naticonema on this.

Cropped, brightened:

The shell is about a centimeter in diameter, and it is not easy to tell but from what I can see it is conispiral.

Hello everyone, 

I haven't posted on here in a while but just found this item while breaking up a large piece of shale.

It was hard to photograph it as the thing is only around 3mm wide.

It comes from the Windom shale and is preserved in the same color as trilobites I have found there. Some of the item is still in the rock but a profile view of it shows a U shape. I haven't seen anything like this from here I originally thought that it may be a hypostome but it appears too round and the shape doesn't seem to match the hypostomes I have seen.

Sorry that the pictures aren't great, it was hard to get it in focus as it is so small.

Any help is appreciated.

There is also this object that I have had for a while, I am guessing that this one is actually a Greenops or Bellacartwrightia hypostome imprint. The domed part is 5mm wide but if you include the projections out to the side it is around 1 cm

Hard to tell with # 1, but I would lean toward a Bellerophontid gastropod of some sort.
