SE Texas - Toe bone (phalanx) to what?

[johnnyvaldez7.jv]

Found this small toe bone (phalanx) today in an area where I find a bunch of Pleistocene mammal bones.  It is rock solid. Heavily mineralized. Unfortunately, the business ends are eroded and worn. Hopefully these photos will help with an ID. It is 50 mm or 1.99 inches from end to end. Thanks.

Didn't think it has the curvature for a predator.  So perhaps a prey such as deer?

This appears to me to be the shaft of a deer calcaneum.
