River Falls, AL - Lisbon Fm., Eocene

[Sauropod19]

Hello! I just completed my second trip out to Point A Dam in River Falls, AL and found a couple of interesting things that I cannot seem to ID. Due to traveling, I only took a few pictures and had to use a coin for scale before moving to my next destination, so I apologize for the lack of quantity and quality of my photos. When I get time, I can take more images of the samples below upon request. Thank you!

 

1: I’m leaning toward Angel shark (?)

 

2: Legitimately do not have a clue… Maybe stingray related as it is long and cylindrical but it has confounded me. It does have a hole through the center that was difficult to image, presumably for soft tissue.

 

3: Once again, I don’t have a clue. The bottom of these pieces are smooth and concave below the central “peak.”

 

4: Miscellaneous pieces. Very well could be nothing but figured I may as well post them.

The first one is Orectolobus ziegenhinei. The second is Cylindracanthus and the third are boxfish dermal plates.

That is super impressive! Thank you so much!

Number Four, bottom right looks like it could be a piece of turtle shell.
