Wildlife of the Falkland Islands a hunting dog. However, a 2009 DNA study by scientists at UCLA suggested that the warrah arrived on the islands long before humans migrated to the New World, possibly during one of the particularly intense cold intervals 340,000 years ago, 150,000 years ago or 25,000 years ago. Its nearest relative was the maned wolf, an extant South American canid. It became extinct in the mid-19th century as human settlement spread. 14 species of marine mammals including killer whales, Peale's dolphins, Commerson's dolphins, leopard seals, southern elephant seals, and southern sea lions frequent the surrounding waters. The elephant seal, the fur
Extinct comet the Hubble search for transition comets. Comets such as C/2001 OG108 (LONEOS) may represent the transition between extinct comets and typical Halley-type comets (periods of 20–200 years) or long period comets (periods longer than 200 years). Minor planets of the group of damocloids have been studied as possible extinct cometary candidates due to the similarity of their orbital parameters with those of Halley-type comets. Dormant comets are those within which volatiles may be sealed, but which have inactive surfaces. For example, 14827 Hypnos may be the nucleus of an extinct comet that is covered by a crust several centimeters thick
