I found a turtle in the road in upstate NY around the Albany area. It had a 8" wide oval medium dome shell with a saw tooth edge at the rear. The pointed saw teeth were about 3/4" apart and maybe 1/2" long, there were approximately 6 or 7 of them. As I helped it off the road with a shovel it glared at me with a light cream colored open triangular mouth. It was covered with mud so I could not get any color info. Sorry no pictures. Any idea what I found?
