Jaw bone age help.

[T3Guy]

Hey guys,
Was wanting to see if someone could help me out with an approximate age by looking at this jaw bone. If anyone can help, that would be greatly appreciated.

 

[pass-thru]

4 years old or older

I think there enough wear on third molar to go 5.5

4.5

Thanks guys, I'm not to good at looking at the jaws and aging but would love to learn. Buddy of mine hit this deer a few weeks ago with a bow and he started showing back up on camera. A doe got him in trouble a few days ago and we were trying to figure out how old he was. He had a green score of 134 7/8
This is a picture of him back in early season.




This is last week first time he showed back up since he was hit.



Our thoughts was a 4 year old by this pictures but we thought we would see what you all thought.
Like I said I appreciate the help
