A prehistoric Eskimo culture that settled in the eastern Canadian Arctic and Greenland around 1000 BC and lasted until 1000 AD when it was replaced by the Thule culture. The earliest manifestation, known as pre-Dorset (in some areas as Sarqaq) is represented at sites on Baffin Island and dates from c 2400 BC. The Dorset subtradition developed from pre-Eskimo Arctic Small Tool tradition. A typical site of the late Dorset subtradition is Port aux Choix 2 in western Newfoundland with house and storage pits. They hunted sea mammals and caribou. The tradition had a stone tool assemblage of end scrapers and spear points and they were also known for beautiful carvings of animals and humans in bone, ivory, and wood.
