Here's a general idea:
* Average Size: The average length of a bison horn is about 2-3 feet.
* Range: Some horns can be as short as 1 foot, while others can reach over 4 feet long.
* Sex: Male bison (bulls) typically have larger horns than female bison (cows).
* Age: Older bulls tend to have larger horns than younger bulls.
* Breed: Some breeds of bison, such as the Plains bison, tend to have larger horns than other breeds.
Important Note: Bison horns are not the same as deer antlers. Bison horns are permanent structures made of keratin, the same material as human fingernails. They are not shed and grow continuously throughout the bison's life.
