"Arganodus" is an extinct genus of Ceratodontidae (lungfish). Its fossils have been found in the Redonda Formation, New Mexico,cite web |url=http://gsa.confex.com/gsa/2005RM/finalprogram/abstract_86716.htm |title=The Microvertebrate Fauna of Shark Tooth Hill, Redonda Formation (Late Triassic, Apachean), Quay County, New Mexico |publisher=Andrew B. Heckert, Specer G. Lucas and Adrian P. Hunt, New Mexico Museum of National History |date=2005 |accessdate=2008-07-14] and the Cumnock Formation, North Carolina,cite web |url=http://gsa.confex.com/gsa/2006SE/finalprogram/abstract_101756.htm |title=A New Microvertebrate Fauna from the Upper Triassic (Norian) Cumnock Formation, Durham Subbasin, North Carolina, USA |publisher=Andrew B. Heckert, Vincent Schneider, Paul E. Olsen, and Sterling Nesbitt |date=2006 |accessdate=2008-07-15] although the North Carolinian specimens are smaller than most recorded specimens. Fossils have also been uncovered in the Petrified Forest National Park.cite web |url=http://www.nps.gov/pefo/naturescience/vertebrates-of-the-late-triassic.htm |title=Petrified Forest National Park - Vertebrates of the Late Triassic (U.S. National Park Service) |publisher=www.nps.gov |date=2007-04-13 |accessdate=2008-07-15] It was first named by Martin in 1979, and contains two species, "A. dorotheae" and "A. atlantis". "Arganodus" was probably similar to modern lungfish, and lived in underwater burrows during dry periods until monsoons occurred.
