Aguja Formation (TX) Matrix Unknowns

[JamieLynn]

Hi y'all! I recently got some more Aguja Formation Matrix and have had a great time looking for the little stuff - even found my first dino tooth! But of course, there is quite a variety of things that I can't ID and would be greatly appreciative of your help! 

 

1. This first thing is my favorite! I don't know if it's a fish tooth or a denticle or what, but it's so cool looking!! 

Aprox 2mm

 

 

 

 

 

2. I THINK this is a croc tooth? I did a little poking around trying to ID the above and this one and stumbled upon Champosaur as a possibility perhaps?  4 mm

 

3. Is this part of a Croc Scute? It looks remarkably like the amphibian skull structures I'd found in the Permian micro matrix, which makes me think it might be Croc.... 

Size 6mm

 

4. What the heck is this? Denticle? It's obviously bone, but almost like a scale?

Size: 8 mm

 

Back

 

5. Fish Tooth? Size 4mm

 

 

 

6. Also fish tooth? Size 4 mm

yes, a fish tooth. Paralbula, maybe Paralbula casei.

Thanks @Troodon! I didn't think about Hybodus, but, yes, those angular planes are consistent with hybodus. Thanks so much for the IDs! 

@Al Dente Thank you!!! It's just one of the coolest little teeth I've ever seen.

Really cool stuff!

@PFOOLEY  Thanks for the PDF! I have not seen that one yet.

You are welcome...I hope it is helpful. I do have to agree with Frank's identifications...the Hybodus and Melvius teeth are accurate with what I've seen in the Kirtland/Fruitland as well as in literature.

 

Go find more!

Great finds and photography!  According to Pfooley's reference material, your Hypodus tooth is a RARE find. Nice job.
