Post Oak Creek Texas Unknowns (Micros)

[JamieLynn]

Hello all! A batch of new unknowns found in my micro matrix! Any help will be appreciated! Cretaceous Eagle Ford formation.

 

1. Interesting geometric pychnodont tooth? I know they can be rectangular, but this one is oddly shaped. Size 5mm

 

2. Strange "fat" tooth". It looks sharky but the width of the base is throwing me for a loop. Perhaps the cusplet of a bigger tooth? Size 5 mm

 

3. An odd striated tooth. Size 6 mm

 

4. A very pointy something. I thought it was a Scapanyorhynchus tooth at first, but it's not quite right. Seems more "fishy".

Size 6mm

 

7. Not even sure what to make of this. It has bone texture, but also other stuff?

Size 8mm

 

8. A weird little double pointy thing. Those two sticky up "stalks" are just strange. Size 2 mm

 

9.  Thinking this might be turtle? Very small though.  Size 12mm

 

10. Lastly, a little vertebra that might be snake 

Size 7mm

This looks sharky to me. Just a guess, but maybe a symphyseal/parasymphyseal tooth?

Nice micro collection!

#1 looks like a drum fish tooth.

well, I believe this is a scapanorhynchus symphyseal  and it definitely has more of the enamel like shark tooth-ness. And the unknown one has a weird "zig-zag" to it.

#1 looks like a pseudohypolophus ray tooth. Need to see a side view to be sure.

1. Pseudohypolophus mcnultyi. Welton and Farish say this species is distinguished from other Texas rays by their hexagonal crowns.

2. I'm thinking this is a cusplet as well. Probably no way to say for sure from what, but its shape is reminiscent of goblin.

3. goblin symphyseal

4. goblin symphyseal - I haven't seen a rooted fish tooth like that

5. not seeing anything...

6. not seeing anything...

7. really rough Squalicorax sp.

8. Dunno, could be bryozoan covered in stuff, or just geologic

9. Not seeing any bone here, could be a rock...

10. Need more views.

Snake:

hahahah!! My numbering is pretty sad.....completely skipped over 5 and 6. Ah well. Here are a few more views of vert. It is a bit roughed up.: 

 

 

[ThePhysicist]

Not sure about the vert.

I think the vertebrae is a Pleistocene snake/lizard vertebrae. Pleistocene stuff gets washed into post oak creek all the time. That would be my guess at least.

A question...could it be a coniasaur? I swear I saw a picture of a coniasaur vert online but now I can't find it anywhere. It looked very similar from what I remember (but that could just be because it is reptile).  I found a coniasaur tooth and I know they have been found in the POC.

I suspects #9 may be partial of upper part of arm or leg bone of small animal. Just a rough guess as I hadn't been studying bones yet.
