    Older broomed Dall

    The groove formed at 18 months tends to be oval shaped on the butting surface; shallow and smooth while the 30 months groove usually forms a notch on the upper part of the outer surface and pronounced bump on the inner surface of butting edge and the butting surface is usually flat.

    On this set of horns the first well defined groove shows all the characteristics of an “18” month (2 year) growth ring.

    Older broomed Dall

    Counting the ring formed 18 months as “2” assumes the animal dies after June of the following year. If the animal dies in say April the age would be “1” though in its second year of life. An animal with eight annuli is seven until the next May or June. Since most animals harvested in the fall...

    I believe it is unusual - however, I can check with a sheep biologist. Will try to find out tomorrow.

    These older rams often provide challenges in determining annuli at both the base and tip. Will try to mark annuli and repost. Hope these models help.

    Still taking too much time, but getting faster. Hopefully can get the process refined to the point it that it will be feasible to use for educational purposes.

    Help aging rams ? Family banter

    Given this sheep probably has greater than 440 degrees of curl it would be exceptional at any age! Congratulations

    Is that the sheep that was displayed in Sportsman Warehouse?

    The angles on the back of the horn are especially helpful on older sheep when trying to identify rings closer to the base.

    I was wondering which ring was counted as “”three”.
