A cow's left foot shows significant fusion between its third and fourth metatarsal bones, a condition known as ossea metatarsalia tertium et quartum. This specimen measures 204 millimeters in length, 57 millimeters in width, and 48 millimeters in height. A structured light scanner, the Artec Space Spider, was used to perform a three-dimensional scan of this anomaly.
