In trying to find what animal this horn came off of I tried Google looking for oxen, I
came up with Aurochs (Bos primigenius) ,the ancestor of domestic cattle,is an extinct
type of large wild cattle that inhabited Europe,Asia and North Africa.The species survived
in Europe until the last recorded aurochs died in the Jaktorow Forest, Poland in 1627.
By the 13th century, aurochs existed only in small numbers in Eastern Europe, and the
hunting of aurochs became a privlege of nobles, and later royal households. They were
not saved from extinction.The aurochs was one of the largest herbivores in postglacial
Europe. The estimated weight of a bull was 3,300 pounds. Aurochs horns could reach
31 inches in length with a base diameter of 7.9 inches. If anyone is interested there are
28 pages on this animal under oxen giving all kinds of information on Google.
