Not sure - Palo Duro Canyon TX area

Not a clue but interesting form. My first thought was a weather form ammonite fragment? Found near the Palo Duro Canyon in TX. The area in question includes the following formations. 

 

Tecovas Formation: Triassic

Trujillo Formation: Triassic 

Ogallala Formation: Late Miocene to early Pliocene 

 

Any help or direction would be appreciated.

I think it's geologic. Settling and slumping of sediments before they lithified, or perhaps deformation during tectonic movement.

I agree. 

Obviously, the ammonites were extinct long before the Miocene and hadn't evolved in the Triassic.

And although other groups of ammonoids were about in the Triassic, it doesn't look like them to me. 

Nautiloid would be more likely, but it just doesn't look of organic origin IMHO

Ammonites were around during the triassic.

 

I agree that the piece in question is not a fossil.
