One adult metatarsal measures 5·7 inches long and ·4 broad, and another 5·2 long and ·4 broad at the narrowest part of the shaft. In the modern specimen this bone is 4·8 long and ·5 broad.
Three specimens of adult radius have been gathered, measuring in length respectively 6·6, 6·, and 5·9; while in the modern specimen the corresponding bone is only 5·2.
Two complete humeri are among the specimens gathered. The largest, not quite adult, is 5·7 inches in greatest length; while the other, quite adult, is only 5 inches long, and in the modern specimen the humerus is 5·2 long. Four additional specimens of the lower end of the humerus have been obtained; and one of them is decidedly larger than the largest complete specimen, and another decidedly smaller than the smallest complete bone.
The sheep was therefore long and slender legged, like those found on other Ayrshire deposits. But it is difficult to determine whether the differences in size depend on sex, or some other cause, such as cultivation.
