re: Need help aging these deer & WYSI?

By looking at the jaw shelf it is clear the second deer is young, most likely 2.5. the First deer is a tricky deer, we have the worst view to age a deer but, the deep jaw shelf indicates that the deer is mature. I cant tell without a better angle how old. But if you can say for certian the seond deer is 2.5.

The deeper the face looks (Top of head by horns down the the jaw bone) the older the deer will be. This is clear difference in these pictures.
