Thanks for the additional pics. It is a juvenile female Mississippi Map turtle that has a broken yellow crescent behind the eye. The yellow crescent behind the eye normally is continuous. Notice the turtle has a round yellowish spot in the middle of the chin. This is characteristic of a Mississippi. Also notice on your False Map turtle the hairline yellowish lines on the neck run continuously up to the eye socket. On the Mississippi they do not.

Good luck with both.
