JacksonFarmer NSR finds

[JacksonFarmer]

This will be my first attempt at identifying and photographing my collection of NSR finds. Please correct any of my mistakes. I can easily modify the photo captions. Sadly I haven't figured out how to italicize the font on my photo editing app yet.

 

 

 

The only phosphatic mold of a bivalve that I have found. It's a dead ringer for the same specimen photographed in the NSR Fossil Hunter's Guidebook. Current consensus is that the Guidebook is wrong for labeling this A. argentaria.

Thanks to Thomas.Dodson for the help with this one. This was found sifting through a plate of gravel matrix on my couch!

[JacksonFarmer]

Not too spectacular but this one always makes me happy.

That gastropod is very pleasing to the eye.   
Thanks for showing it.

Welcome to the Forum. Nice coral. I found a lot of slightly younger ones of the same genera along Lake Texoma.
 

I think the guide is wrong. Here are Anomia argentaria with original shells from NSR. Note straighter hinge lines and no interior concentric growth lines. Also note the growth lines are concentric at a point more away from the hinge line.

Interesting finds.

Thank you for sharing. 

[JacksonFarmer]

Yes, DPS Ammonite, I believe you are correct about the Anomia argentaria.

The Guidebook is the only place I could find something similar.

 

So that one is getting re-labeled as unkown.

This chunk was found on the Western end of the river. The rock does not look or feel like the Ozan fm.

 

Is this possibly a piece of Austin Chalk?

I believe I see turitella sp. and maybe nephia sp.?

Silly humans brought it there. It is Cretaceous Cordova Shell Sone from Austin, TX. Trigonids and turritellilid molds are common.

Hahaha! I love it.

Everytime I think I might understand something, blam, the universe reminds me how little I know.

After referring to my books and some member galleries, I'm gonna take a stab and say Oxytropidoceras sp. ???

With a shell imprint on the base of it.

I really need help with this one. Looks like it is broken and should be a bit longer.

This last find is a catfish spine... I find them all the time in Peace River Florida (both Fossil and modern)

Oxytropidoceras species are an Albian fauna...much too old for the North Sulphur River.  

 

You might compare it with Hoplitoplacenticeras.

I agree with JohnJ, Hoplitoplacenticeras.
