Turtle scutes

I was digging in the Peace River area of Florida and found several examples of my favorite turtle scute, the ones that run down the middle of the back. Fourteen scutes was quite a haul for me (the 14th scute was small and I missed it when setting up the photo and though they don't have the dark gloss that comes with many fossils from the Peace River proper, the mix of interesting colors makes up for it.

I believe the lower left scute is from the middle front or back of the the top shell.

Pleistocene epoch.
