Turtle

My ID was concluded from first hand experience and from "A Field Guide to Oklahoma's Amphibians and Reptiles"

Hi Robert & welcome to Project Noah!
I've changed the order of your photos as we couldn't see the turtle in the image you had first. I've also blanked the scientific name box (removed "reptile") & ticked "help me ID this species", so that the community can help you identify the exact species of turtle here.
