Ernst Quarries ray or fish teeth, maybe?

[ChristineR]

The specimen was found at Ernst Quarries, Temblor formation, round mountain  silt. This reminds me of a ray plate except the plate  is somewhat wedge shaped, with very thin teeth (?). One longer “tooth” remains in the matrix. 
 

Sorry I couldn’t clean it up better, while attempting to do so, it popped out of the matrix. I hope to glue it back in place  to complete the prep, but the risk of further damage may change my mind. 
 

This prep has revealed multiple specimens, changing the plan and approach again and again. Nice problem to have,right? The last photo shows one of three larger specimens in the original  matrix. 

 

 

I will seek additional IDs and prep advice in separate posts.

Blurry pictures

These photos are much too blurry to make out much detail at all.

Thank you, and I'm sorry, I agree! They looked so much clearer on my small phone screen. (red faced emoji)

I will post new pictures this evening.

seal phalange

Thank you. I’m wondering if it is possible to ID seal phalanx to species, if so, will I need to remove the specimen from the matrix? 

 

The only resource I can think of is the society of paleontology. I believe only three seals are described from Round Mountain Silt.

I've added better photos, I think.

Let's see if someone here on the forum has either an ID or can put you in touch with someone.

 

One idea is to reach out to the Buena Vista Museum of Natural History in Bakersfield.  Link: https://www.buenavistamuseum.org

Sounds right up Bobbie’s alley. @Boesse

Thank you! I will reach out to them. I was ables to clean some of the "plate", which only raised more questions. I appreciate your advice.

1) That's a Myliobatis median tooth fragment, it seems.

2) It is generally not possible to identify isolated pinniped phalanges. That being said, it is most likely Allodesmus, the most common pinniped in the assemblage.

Thank you @Boesse! The  small "teeth" threw me off. In your opinion, are these interlocking ridges which hold the teeth together? I still can't grasp the image or orientation.

The comb-like structure are the roots of the tooth that lock the teeth into the cartilaginous parts of the jaw!

Thank you, again. I am amazed at the preservation found at STH. Ray plates are typically an easy ID with the typical preservation.
