Cementum aged critters - Let’s see them..

[It’s Bucky]

At age 1.5 the front two (I1s) permanent incisors are in, and noticeably bigger than the others. At age 2.5 the I2s (next to the I1s) are permanent and larger. At age 3.5 the I3s (next to I2s) are permanent and large. At age 4.5 the last set of incisors, technically canines I think, are now permanent. After age 4.5 it becomes guesswork.

Here's a pic of the incisors from a pronghorn that is 3.5. The I4s/canines (circled) are noticeably smaller than the others.

I’ve got a couple pronghorn jaws I’m going to take a look at and see if this lines up, thanks for the info

5.5, A reliability, believe it or not

Sure would think there would be more mass for a 5 year old buck, long tines though.
