Ancient population dynamics of the sea cow (Hydrodamalis gigas Zimm., 1780) in the late Holocene.
Doklady Biol. Scis. 326(1-6): 403-405. 1 tab. 1 fig. Mar. 1993.
–Transl. from Russian; originally publ. in Dokl. Akad. Nauk 326(3): 570-572, Sept. 1992. Radiocarbon dates on apparently reworked rib fragments from Bering Is. indicated ages of 500-2250 years. Based on the fact that most of the dates fell between 1000 and 800 years B.P., the author concludes that the population size declined as a result of climatic cooling about 2000 years ago and again during the Little Ice Age (14th-17th centuries A.D.). Given the small sample size and inadequate documentation of sampling procedure, this conclusion seems to go beyond the evidence.
