While crossing the highlands of Central Asia in the 13th century, Marco Polo was the first Westerner to describe these animals, giving rise to the species' popular name – the Marco Polo sheep. Argali (Ovis ammon) are the largest species of wild sheep, distinguishable by their massive, curling horns that grow up to six feet in length. Molded from an actual skull and horns, our replica is finished by hand to capture the realistic detail of the original.
