Eskimos, the Native group most familiar to non-Alaskans, were originally divided into two subgroups: the Inupiat Eskimos settled in Alaska's Arctic region, and the Yup'ik settled in the west. To combat the cold, seasonal food was stored against future shortage, in particular against the privations of ...
This list of the Cenozoic life of Alaska contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Alaska and are between 66 million and 10,000 years of age. Mummified specimen found in Alaska of the Pleistocene-Holocene Bison priscus, or steppe bison.
The Upward Sun River site, or Xaasaa Na’, is a Late Pleistocene archaeological site associated with the Paleo-Arctic tradition, located in the Tanana River Valley, Alaska. Dated to around 11,500 BP, [1] Upward Sun River is the site of the oldest human remains discovered on the American side of Beringia. [2] The site was first discovered in 2006.
Invertebrate remains were also found with the plants. [8] Pieces of Cretaceous amber have been found on the shore of Nelson Island, which is located in the Bering Sea. [9] Dinosaurs lived in Alaska during the Cretaceous. [1] Alaska remained tectonically active into the Cenozoic era. Volcanism produced the Aleutian Islands. [1]
Coelacanth. Coelacanths (/ ˈsiːləkænθ / ⓘ SEE-lə-kanth) (order Coelacanthiformes) are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. [2][3] As sarcopterygians, they are more closely related to lungfish and tetrapods (which includes amphibians, reptiles, birds and mammals) than to ray-finned fish.
The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include Haikouichthys.
Paleo-Arctic tradition. The Paleo-Arctic Tradition is the name given by archaeologists to the cultural tradition of the earliest well-documented human occupants of the North American Arctic, which date from the period 8000–5000 BC. The tradition covers Alaska, and expands far into the east, west, and the Southwest Yukon Territory of Canada.
