That being said, having pulled numerous jawbones from deer on my farms that I knew the ages of from successive years of trail camera photos, I would age that deer as 4.5 on my farms. For whatever reason, my local deer just don't show as much wear for age as other locales (prob diet related). If there is any significant wear on M2 (not necessarily dentine classically wider than the enamel), the deer is 4.5. This is where knowing your local hunting area comes in handy.
You are going to have to explain this one to me. For the life of me, I cannot wrap my head around recording an age that you KNOW is incorrect.TheLBLman":100y04ze said:Knowing a particular buck is 4 1/2, but the method of aging says 3 1/2, to maintain the integrity of the trend data, 3 1/2 should be recorded.
I've seen this hold true for SEVERAL bucks at Ames over the year, thus why I am fairly quick to go a year older than most on TR&W method. Also, if you take the time to research the Severinghaus method and the accuracy of a lot of biologists over the last 50 years, you will see that most of those "in the know" consistently underage deer 4.5+ by the TR&W method. There you have it, my basis for going 4.5 on this one jawbone. :tu:megalomaniac":1w108zvs said:For whatever reason, my local deer just don't show as much wear for age as other locales ........
I agree we should have an "or older" after any estimated age,Andy S.":2rxp0buf said:You are going to have to explain this one to me.

Wouldn't all ages after 3.5 require a "+" after it? If so, isn't recording 3.5+ about the same as 4.5+ for trend data for most fair chase hunting clubs, especially in TN?
I would say study the wear of the jawbone a little better and learn to more accurately age the jawbones for your area. What say you?
