Mosasaur flipper bone?

Recommended Posts

I found this fossil in the North Sulphur River.

The only thing that I think fits is a flipper bone to a Cretaceous mosasaur. Any thougts?

Looks more like a phalange to me but I am no expert...

I also think that it may be a mosasaur phalange. Here are a bunch of Tylosaurus phalanges from Kansas as an example.

If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM!

Those phalanges that Macrophyseter has posted are plesiosaur, not mosasaur.  Mosasaur phalanges are much longer. 

That said, I'm not sure what your fossil is Benjaminpb.  It could be a plesiosaur phalange, but I think it is not flat enough for that.  My guess would be a badly eroded mosasaur vert., or possibly turtle material.

Thank's for the input Ramo.

at this point it's really a question mark I guess.

I have mosasaur verts and this looks nothing like it. If it's a vert then it's the most worn one I've ever found. It doesn't look like anything I've been able to find pictures of, other than a phalange. I'm not saying you're wrong though. I guess I'll just shrug my shoulders until I find out for sure. I have a couple more finds like this one that I posted that went mostly ignored.

maybe because I posted a few at once....I dunno.

You can always bump them to see if someone can help.
