ABSTRACTThe modern deer farming industry can be traced back through the centuries at least to Roman and Greek times. Archaeological evidence from China and Europe suggests that deer of several species may have been partially domesticated or at least habituated to humans many centuries before that, including during the Mesolithic. The techniques described by Aristotle and Roman authors are used today by deer farmers in many countries. The farming of wapiti in North America was first described in 1877, and seriously considered by the U.S. Biological Survey in 1908. As of February 1993 deer farming was being carried out in 21 countries. 相似文献

A new ichnotaxon is recognized in the Perkasie Member of the Passaic Formation (Upper Triassic) at the Smith Clark Quarry, Milford, New Jersey. Spongeliomorpha milfordensis is a small trace fossil possessing sharply incised partial wall striations which form a distinctive angle with the axis of the burrow. It is construed as a deposit‐feeding structure possibly formed by aquatic insect larvae along the margin of a lake. 相似文献
