Big Florida Astragalus? Or Something.

[timhigg]

This was found on a Florida beach after a storm 

near Sebastian Florida.  Pretty large bone in my estimation, but you can see the dimensions in the photos.  About four inches long.

 

I think it might be an astragalus, but I haven't able to match it with a particular animal.  The grooves on the inside of the two lobes seem to be deep.  (Just below inch three and four on each side of the center channel.)  I didn't see anything like that on the various photos for the animals I found.  Must be fairly large though.  What do you think?   Thanks much!

I think it's from a bit lower, in the foot or toe of something big.

I am not sure that it is an Astragalus, but you should be interested in this thread:

and this one, one also.

I wonder if @Harry Pristis is around.

Looks like a horse femur, distal epiphysis.  For comparison:

I was gonna guess horse or deer femur end, but based on Harry’s guess, I’d say horse.

To fit a deer it would need to be the size of a moose. I'm not sure Florida can muster one that big.
