Lastly, just below that crazy mix of land and sea, I kicked this little specimen. I want to think it is of the sea but it may in actuality be nothing but an interesting looking rock. Sponge?

 

This one is about 2" (50mm) wide and 3/4" (20mm) thick. It has a cupped bottom and is circular when viewed from above.

 

Consider a Haplistion species such as sphaericum from the Desmoinian in New Mexico. Picture from reference below.

That is a better hypothesis than my earlier suggestion.

Consider Aviculapecten. Probably not a Cardiola since they are from the Silurian and Devonian.

Cardiola lyoni is Carboniferous, but probably not as late on as the specimen shown. 

I think you mean Aviculopecten, which seems like a better starting point.

@Tidgy's Dad  I thought I was on a mind trip...your tortoise started to chase after me. How long has it been rushing at the screen and I did not know?

 

@DPS Ammonite @FossilDAWG thank you both for providing me direction

Tidgy's been my avatar for quite a while. 

She's always tearing about the place, the little minx.

I made a quick visit to this new locale as I owed Tidgy's Dad a photo of a UF(ossil)O. 

 

This particular find had me thinking I'd finally found some calamite in this locale that seems to be predominantly cordaites and ferns. On 2nd thought, this may just be an ultra-wide cordaite strap of width 6 cm.

 

@paleoflor  hi, I was hoping you might share some thoughts if this is just a wide cordaite strap or perhaps a calamite? A few photos down this page  I found something resembling annularia. Until this day of searching I'd not found calamite preservation but feel there should be more than cordaites and ferns. 

 

 

I also found this shredded cordaite leaf. A new type of find for me concerning plant leaves.

 

[Kato]

I was quite pleased to find the other half of this cordaite with elliptical hole. Still wanting to believe it is insect predation and one day I will find an insect fossil here.

A nice spray of ferns

Lastly, there is just not enough here to conclude this may potentially be calamite annularia on the right side.

From the other fern/calamite location...it somehow was hiding in my rucking pack hipbelt pocket from a week ago.

Hard to say for sure...

@paleoflor  I have zoomed and cropped that pic, then put some areas marked in orange that seem much more like features seen in calamite fossils. I've not seen a cordaite fossil with a split like the orange area on the right side of this photo
