North Sulphur River and Post Oak Creek IDs

[flyingpenut]

I was wondering if anyone could help with some NSR IDs? I also have one item that looks like a tooth from POC. It is Item 1. All other items are from the North Sulphur River. 

 

Item 1. Possible tooth?

 

Item 2. Calcium nondual?

 

Item 3. Pleistocene turtle? It is extremely thick and hard. 

 

Item 4. Some have speculated it as turtle plastron bone or Plesiosaurus paddle bone. 

 

Item 5. Some type of Geological crystal nondual? 

 

Item 6. Coprolite or just rock?

 

Item 7.

• Your first item certainly looks like a tooth. But closer-up and higher resolution images will be needed to confirm this and potentially identify it (is it the same one as in this thread?).
• The way the bone fibres run on item 4 is definitely very reminiscent of those often seen on distal end of plesiosaur podial bones, an hypothesis the slight curve in the bone seems to support. I also believe turtle plastron of this size would show vascularization on the sides, but am not familiar enough with this type of material to say for sure (one would expect that the vascularization is only visible if the bone is broken)... My gut feeling, however, is that it isn't turtle plastron. Plesiosaur podial seems more likely to me...
• Item 6 does look like fish coprolite to me, with it's twists, but may be @GeschWhat can confirm that.

Other than that, I think most is actually geological. Item 2 does indeed look like a calcite nodule, but may be the remains of a sponge, while in the photograph with the many red and black coloured pieces accompanying item 3, the red and black pieces with wavy line patterns would be the remains of ammonites and bacculites.

 

On the whole, however, I think that members with more experience in NSR would be able to help out more... Let me tag some of them: @ThePhysicist, @JohnJ, @Jared C, @Titan and @NSRhunter

2.  Looks like a mastodon tooth fragment.

 

3.  Is an eroded piece of decorative ceramic.

 

4.  I lean more toward turtle bone....

 

5.  Geological; part of a septarian.

 

7.  Looks like slag.

I'm not in a position of knowledge to make confident ID's for you, but I originally followed this topic because I'm 80% sure #2 is a Mastodon tooth frag and wanted to be sure. Really cool find, Mastodon material is harder to come by than Mammoth

I didn't have enough time earlier today to include this, but, yeah, I agree on that diagnosis

Some neat finds!

 

I agree that 3 doesn't look like turtle to me.  The turtle shell pieces I've found all have pretty large porous vascularization structures around the edges, especially if they're that thick.  Item 4 reminds me of that vascularization when it's kind of worn down.  But maybe views of the side would help?  

 

@JohnJ What helps indicate item 2 as mastodon tooth?  I would have probably completely passed something like that up if I saw it, and I want to make sure I know what to look for.

This might help.

Thanks!  Those are great examples.  I can see the layering and general shape that could help when I'm hunting.

For clarity, all those images are the same fossil.

Thank you so much for the IDs and assistance.

Thanks for the IDs. That ceramic really had me stumped but now that you have given me an ID it makes perfect sense.

Thanks. I just thought it was a crystalized nondual but now that is see it compared with the Mastodon tooth I am excited.

Thanks. Ill take a few more pictures to post and hopefully that will help.
