The Persian fallow deer (Dama dama mesopotamica) ("gavazn-i zard" in Persian) is a rare ruminant mammal belonging to the family Cervidae. Its taxonomic status is disputed, with some maintaining it as a subspecies of the fallow deer, while others treat it as a separate species, Dama mesopotamica.
Feldhamer et al. (1988) and Geist (1998) included Dama mesopotamica as a subspecies of Dama dama, though it was regarded as a separate species by Haltenorth (1959), Ferguson et al. (1985), Uerpmann (1987), and Harrison and Bates (1991). We follow Pitra et al. (2004) and Randi et al. (2001) in treating D. mesopotamica as a separate species, based on a major study on the evolution and phylogeny of old world deer. Thus, the majority of the scientists consider it as Dama mesopotamica. Moreover, Khuzestan Province, where they found the 25 deer, is historically a part of ancient Mesopotamia.
The fallow deer (Dama dama) is a ruminant mammal belonging to the family Cervidae. This common species is native to western Eurasia, but has been introduced to South Africa, Fernando Pó, São Tomé, Madagascar, Mauritius, Mayotte, Réunion, Seychelles, Comoro Islands, Morocco, Algeria, Tunisia, Cyprus, Cape Verde, Australia, New Zealand, Canada, United States, the Falkland Islands and Peru. It often includes the rarer Persian fallow deer as a subspecies (D. d. mesopotamica), while others treat it as an entirely different species (D. mesopotamica).
The male fallow deer is known as a buck, the female is a doe, and the young a fawn. Adult bucks are 140–160 cm (55–63 in) long with a 85–95 cm (33–37 in) shoulder height, and typically 60–100 kg (130–220 lb) in weight; does are 130–150 cm (51–59 in) long with a 75–85 cm (30–33 in) shoulder height, and 30–50 kg (66–110 lb) in weight. The largest bucks may measure 190 cm (75 in) long and weigh 150 kg (330 lb). Fawns are born in spring at about 30 cm (12 in) and weigh around 4.5 kg (9.9 lb). The life span is around 12–16 years.
