Need help with a couple unknowns

[Balance]

Hello and a happy weekend I hope. 
 

These two showed up in my pole scoop. Im pretty stumped…waters high. Time to gift stuff out…

 

 kinda think item two is a fish fin or something. Very interesting attachment articulation. Item one I originally looked at as a gator vert with the usual damage. Almost tossed it back but realized it has two convex sides. Don’t quite know how that would work as a vertebrae… hip socket of some kind? 🧐🧐

 

Any suggestions appreciated. Water picked up speed and dropped 1’ in 2 days!! It’s been so slow it’s nice to see it dropping. 

 

Bone Valley finds. Peace River Member. Age range from Miocene to end of Pleistocene. 
 

Thanks!

I love your photos , You must have some specialized equipment and photo Applications.

 

On the 1st I am wondering if it is a specialized Alligator vert that plugs into the skull.

 

On the 2nd I am thinking some sort of Fish skull..

 

I have not seen either previously... @Plantguy@Al Dente

Thanks Jack, I was just looking at this thread as well. The 2nd is a tilly bone. I still havent figured out from which fish (if that is possible...jacks come to mind but there are many others that had/have these overgrowths)...Very Neat find!!

I agree.

No.1 sure looks like a vert to me, though I haven't seen many biconvex ones.

pachy-pleuro-whatnot-odon's comment linked above includes a couple images that are wonderfully useful and I come back to often. The second image lists turtles as an example of an animal with biconvex vertebrae. Anyway, cool find and I look forward to seeing what this thread shakes out.

Thank you , @Shellseeker @Plantguy and @Al Dente

 

Tilly bone it is. Definitely the most detailed of those I have found so far. 
 

Jack, nice job!

 

Took a minute but that is Ann alligator vert and it is a specific one. Not the skull though. First vertebrae in the tail! 
 

Monday is upon us… here we go 😉

Just last years basic IPhone and it’s standard photo editing. Lots of light, plain background and then edit the wash out down to your finish instead of trying to edit up to a finish.

Curious, does anyone know what anatomical part of a fish that tilly bone would have gone to?  I ask because I once found a Native American bone hairpin made from whatever kind of fish bone that is.  Thanks

tilly bones are hyperossified ribs, fin spines, or fin supports. yours *tentatively* looks like a fin spine, but its difficult to tell when worn.
