Pteranodon wing display

Pteranodon Sp.

Logan County, Kansas

Niobrara form. Smokey Hill chalk

Santonian-Campanian, late Cretaceous 

Im not exactly sure which bones they are, and I’d appreciate any input about it, but based on the significant difference between the 2 connecting bones, I’d imagine it’s one of the metacarpals and the connecting 1st phalanx.

(I’m very proud of the display/storage box I made for it. Removed box innards and carved tightly fitted slots in padding from an old crystal wine glass box. Who says having random stuff sitting around for decades is a bad thing!?)
