NSR Finds

[Mercedes Coxca]

Hey y'all! This is my first ID post, so please tell me what I should do/change for future posts <3

These are all fossils I have found in the North Sulphur River in the last two months. I'm only asking about a few in the picture because I know there's a lot and I figured I'd only focus on a few at a time <3 sorry y'all, didn't plan ahead very well. I have more pictures of all of them though if needed.

1) One (bottom middle) is ID'd (via Dallas Paleo Group on FB) possibly as coprolite or a 'jumble'?- looking for clarification as well as what the things inside the fossil might be, if possible?

2) I think another (the thick triangle whitish thing-top left) might be an oyster/shell thingy? Or a rock bahahaha xD  This is the side view:

3) This one (bottom left) is a pain to get pictures of. My camera refuses to focus properly on it. He's very thin and ever so slightly 'pyramids' in the middle, as well as curves along one side a bit. I thought it might be a scute of some sort? Unsure. It's as dark as it looks in the last picture. Same color as the first. Camera did something funky.

4) And the last (top middle) for now is some weird black rock thing that may be nothing for all I know. Kinda makes me think of a claw in the way it's cupped and has blunt teeth along a ridge. Could be another shell thingy for all I know! It's very thick on one side and then becomes thinner as it reaches the ridged edge.

 

Appreciate any and all help as well as any tips you can give me! I can post more pictures if necessary, just didn't want to overload the post more than I already have. Thank you in advance <3

#1 does appear to be a possible coprolite full of interesting fish scales and other bits.

 

#2 is a fragment of the rudist, Durania.

 

#3 looks like a piece of Cretaceous turtle plastron.

 

#4 could be an internal cast of a bivalve that has borings from other sea dwelling critters.

I think # 4  Could be a broken black phosphate gastropod shell.

I would agree with everything said so far, but would also add that the large crescent-shaped object in the top left corner of the original picture is a chunk from a Durania austensis rudist as well. The smaller curved side indicates where the hollow center would have been placed.

Thank you so much ya'll! I had never heard of the rudists you mentioned before. I really appreciate your time and effort <3 On the Dallas Paleo page, the supposed turtle plastron wasn't fully ID'd (that's part of what made me discover this page), but they were guessing a bone of some sort? But then on another post where somebody found something almost identical  to mine, it was guessed to be a fish scute. Sorry, I forgot to mention that in the OP. I would LOVE for it to be a turtle fossil, haha!

Thank you guys again!

I’m with the others on these IDs. 1 Definitely a great example of coprolite, 2 a rudist fragment, 3 probably turtle plastron however could be fish scute or even possibly a portion of fins, 4 either gastropoda or bivalve cast or fragment from the red zone that produces the black phosphate fossilization.
