Metapodial asymmetry in draft cattle
Authors:L. Bartosiewicz  W. Van Neer  A. Lentacker
Abstract:Traction work by oxen has been well documented in various pictorial and written sources throughout human history. Analysis of metapodial dimensions has been carried out with the aim of quantifying asymmetry related to sexual dimorphism, body size and possibly heavy duty traction work. A modern reference sample of 103 animals from Hungary and Rumania has been used for this purpose. Bone measurements were correlated with bone density and morphological characteristics in order to make the results applicable for the identification of remains from draft cattle in archaeozoological assemblages. Asymmetry is more pronounced in the thoracic extremity and metacarpals of older or heavier animals, sometimes showing excessive widening of the third, medial ray within the fused bone. Relative broadening is also intensive in the distal end of medial metatarsals of cows and oxen. The bone mineral content of the medial carpal region attains mature density first. The weight of phalanges increases for a longer time in the laterally located toes.
Keywords:Cattle exploitation  draft oxen  sexual dimorphism  metapodial measurements  bone mineral content
