8-4-22 Mazon Creek ID

[Nimravis]

I am thinking that this is an example of Palaeoxyris prendelli, if it is, I believe it is my first of this specific one.

What about this piece- kind of reminds me of a weathered eurypterid tail. I have only found one in all of my Mazon Creek collecting.

I agree with this ID.

 

Unsure on ID for second one but does not appear to be Eurypterida to me.  The structure does not appear to preserve rigid shield plates.  Likewise I don't believe A. mazonensis has a center ridge going down the ventral side.

Thanks- I was just looking at other tapered / segmented look of the piece that thought might be a weathered Eurypterid.

I think the second piece is a fern that is oriented slightly obliquely in the concretion

I agree that this is a poorly preserved fern.
