''Archelon'' (from Greek αρχελών meaning ''ruler turtle'') is a genus of extinct sea turtles, the largest that have ever been documented, and the second largest turtles documented, behind ''Stupendemys''.
==Discovery==

The first specimen of ''Archelon'' (YPM 3000) was collected from the Campanian-age Pierre Shale of South Dakota (a geological formation dated to 80.5 million years ago〔Carpenter, K. (2003). "Vertebrate Biostratigraphy of the Smoky Hill Chalk (Niobrara Formation) and the Sharon Springs Member (Pierre Shale)." ''High-Resolution Approaches in Stratigraphic Paleontology'', 21: 421-437. 〕) by Dr. G.R. Wieland in 1895 and described by him the following year (Wieland, 1896). The largest ''Archelon'' fossil, found in the Pierre Shale of South Dakota in the 1970s, measures more than long, and about wide from flipper to flipper. It was a marine turtle, whose closest living relative in the present day is the leatherback sea turtle.〔http://www.uhaul.com/supergraphics/turtle/archelon.html〕〔(【引用サイトリンク】title=Archelon )〕 ''Archelon'' lived at a time when a shallow sea covered most of central North America. Most of the known remains have been found in South Dakota and Wyoming. Though anatomically similar to the earlier species ''Protostega gigas'', it was much larger.〔(Marine Turtles )〕
