During a series of expeditions organized by CERPOLEX/Mammuthus to the Taimyr region in northern Siberia several mammoth (Mammuthus primigenius) carcasses were discovered and subsequently excavated and studied. The oldest specimen is the Arilakh Mammoth (ca. 55,800 BP). Much younger are the Jarkov Mammoth (ca. 20,380 BP) and the Fishhook Mammoth (ca. 20,620 BP), and still much younger are well-preserved Holocene mammoth remains (<10,000 BP). Some paleobotanical data and descriptions of accompanying fauna provide insight into the ecology of the region during Late Pleistocene times. The faunal collapse at the end of the Pleistocene seems to be the result of increasing temperatures, greater humidity, increased snow cover, formation of insulating plant layers, later thawing of the soil, and a lower herbivore density amplifying the climatic effects.
