I shot another mature doe tonight, the jawbone is the one on bottom. I am aging her at 4.5 and looking to confirm. The jawbone on top is from the same farm a few years ago, slightly less wear but also I aged at 4.5. These and the 5.5 from Sat are the only does out of many dozens off this place whose jawbones can be classified as older than 3.5. Out of over 50 does. Now 2 in one week....lol
