Deer

Deer, whose males were known as stags, were large, horned, quadruped mammals which were often the subject of taxidermy.

History
Shalin wore a deer hide which included the antlers and hooves, and wore a necklace made of deer bones. (PROSE: The People's Temple)

In about 120 AD, the Tenth Doctor learned that Roman authorities kept stags as part of a menagerie that included leopards, elephants and a wide range of other, chiefly African animals. Some of the beasts were kept for hunting and others were used to face off against prisoners in local arenas. The Doctor was incensed by the practice, because he knew it would lead to the extinction of several of the species. (PROSE: The Stone Rose)

Deer were often hunted by Edward VII, and in 1902 stag heads "lined the walls" of Balmoral Castle. (PROSE: Revenge of the Judoon)

In 1865 China, Qin Shi Huang, possessed by the Mandragora Helix, brought a dead young buck deer before Cheng, Lei-Fang and Jiang and told them that it was a pig. When Lei-Fang disagreed, Qin had his eyes and tongue removed by his general Zhao. (PROSE: The Eleventh Tiger)

As Hex observed, Joe Hartley's taxidermy workroom contained stuffed deer, including one that was in the process of being mounted. (AUDIO: Night Thoughts)
