Argali Sheep Skulls - These magnificent replicas were cast from some of the largest Argali skulls on record. Argali sheep are some of the world's largest sheep. Some authors recognize up to nine subspecies of Argali. Two of the largest and most well know are the Marco Polo (Ovis ammon polii) and the Altai Argali (Ovis ammon ammon). The Altai subspecies is the largest of all sheep and possess the heaviest horns. The Marco Polo subspecies is particularly known for its long horns.

The longest recorded Marco Polo horns measured 75" (191 cm).

Both of these original specimens reside in the Museum of Osteology collection.
