The very rare head of a hare is stylistically similar to the head of an entire figure of a hare (2 inches long) in the Norton Museum of Art, illustrated by J. Finlay, The Chinese Collection: Selected Works from the Norton Musuem of Art, 2003, pp. 126-7, no. 36. It is noted that "rabbits of this type appear to be a Western Zhou innovation, and examples have been found in Western Zhou tombs at Baoji, in Shaanxi province". See Baoji Yu guo mudi, vol. 2, col. pl. 28 (4), and pl. 185 (4,5). The fragment of the ox is similar to a figure excavated from Western Zhou Tomb No. 63, Marquis of Jin necropolis, Quwo, Shanxi province, illustrated in The Complete Collection of Jades Unearthed in China - 3 - Shanxi, Beijing, 2005, p. 120.
