Archelon (from the Greek roots ἀρχε- arkhe-"chief" and χελώνη chelone "turtle", meaning "ruler turtle") is a genus of extinct sea turtles, the largest genus of sea turtles that has ever been documented, and the second-heaviest turtles documented behind Stupendemys
Nesting site locations and classification are based on several sources: Sea Turtles – A Complete Guide to Thier Biology, Behavior, and Conservation by James Spotila, 2004; The Worldwide Distribution of Sea Turtle Nesting Beaches, Center for Marine Conservation, 1981; and from SWOT.
Sea turtles can be found in oceans except for the polar regions. The flatback sea turtle is found solely on the northern coast of Australia. The Kemp's ridley sea turtle is found solely in the Gulf of Mexico and along the East Coast of the United States. Sea turtles are generally found in the waters over continental shelves.
