Peace River ID help

[PODIGGER]

Picked up the below bone in the Peace River, FL last week. When it came out of the water I thought "knee cap".  The only other one I have found was mammoth/mastodon so it was much larger.  I have spent a lot time in the last week searching for a possible match and the closest I can come up with is bear patella.  I am not 100% sure it is in fact a patella and if so bear.  I would appreciate input to help ID the find.

Thanks!

 

Measurement:

Inches - 2 5/16" x 1 7/8" x 1 1/4" 

MM -     56mm x 48mm x 28mm

Looks more like a femur ball cap, to me at least.

Thanks for your input. I’ll look for some comparison later.
