NSR Red Zone Ammonites ID Help

[historianmichael]

A couple of weeks ago I made my first ever trip to the North Sulphur River "red zone." I had a blast collecting some of the ammonites there- and I thought I did pretty well- but boy is hiking through the river a lot of work. I was really happy to be able to find a nice variety of ammonites, including these two ammonites that I cannot quite seem to fit within the ammonite faunal lists I have seen for the Ozan Formation. I also found this tiny phosphate chunk in a concretion of the "red zone." I would normally say that it is a random chunk of phosphate, but I thought that the banding was unusual. I have no clue what it could be, if it is anything.

 

#1- 3cm wide- what has me confused is the lack of any noticeable suture lines or ribbing

 

#2- 1.5cm wide- the ribbing kinda reminds me of Scaphites sp. and there was a chunk of material that flaked off extending from the ammonite, but the "club-like" suture line has me a bit confused

 

#3- 7mm tall- no clue what this could be
