No, I didn't send the jawbone or tooth in since it was not my deer.
The size and fat comment was based on comparison to other deer taken over the past 30 odd years within a 1/4 mile of where this one was taken. As for aging, the jaw bone or single tooth method of determining is quite accurate, you can get a close approximation by (1.) knowing the deer in the area (Will lives 1/4 mile from the stand, I have over 40 years of scouting on the 250 acres under my belt) and (2.) looking at the teeth (an old cattleman's trick for aging cattle.) Actually, Will and I both "knew" this deer as he was born of a doe that has lived there for years and born 1-2 fawns every year.
Yeah, I've seen deer that "looked" old and turned out to be 2-3 years and I've seen deer that I almost let pass because I thought they were too young, but a nice rack, and they turned out to be very mature deer. (I have a very close friend who use to be with AGFC and got me aging deer a long time ago.)
Kind of interesting if you've ever had to check in a deer on a WMA where the biologist is doing a study and watch them pick ticks, pull teeth, cut hair, take blood samples, etc. They wanted all the check stations to pull a tooth a couple of years ago, but so many of the small country stores (like my sister) told them they didn't have time and didn't get paid enough (they get ZERO $$ for being a check station) so G&F backed off. I'd like to see the biologists and others hang around the check stations the first week of gun season and take some samples. I think it would improve the herd in Arkansas even more.
