Old Buffalo (Bison) Skull from a Bygone Era. Condition is "Used". Shipped with USPS First Class. Here is a old buffalo (bison) skull with the exception of the nose bones. The horns measure 23 1/2" tip to tip with a 10" girth at the base of the skull. This is a very old skull as the buffalo in this area became extinct around the 1850's or before. The weight of just this not complete skull is right at 14# so I would guess it is from a "Bull" buffalo. I have found several of these skulls over the years and have decided to downsize my collection. I have posted a flat .00 shipping fee and if it is over that I will stand the cost myself and if it under that I will charge actual cost no more.
