'''''Supersaurus''''' (meaning "super lizard") is a [[genus]] of [[diplodocid]] [[sauropod]] [[dinosaur]] that lived in [[North America]] during the [[Late Jurassic]] period. The [[type species]], ''S. vivianae'', was first discovered by Vivian Jones of [[Delta, Colorado]], in the middle [[Morrison Formation]] of [[Colorado]] in 1972. The fossil remains came from the Brushy Basin Member of the formation, dating between 153 and 145 million years ago.<ref>{{cite journal|last1=Kowallis|first1=B.J.|last2=Christiansen|first2=E.H.|last3=Deino|first3=A.L.|year=1991|title=Age of the Brushy Basin Member of the Morrison Formation, Colorado Plateau, western USA|journal=Cretaceous Research|volume=12|issue=5|pages=483–493|doi=10.1016/0195-6671(91)90003-U|bibcode=1991CrRes..12..483K }}</ref> It is among the longest dinosaurs ever discovered, with the three known specimens reaching {{convert|33|-|40|m|sp=us}} in length, with the largest individual possibly exceeding {{convert|40|m|sp=us}} in size.<ref name=":0"/><ref name ="Woodruff et al. 2024">{{cite journal|last1=Woodruff|first1=D.C.|last2=Curtice|first2=B.D.|last3=Foster|first3=J.R.|year=2024|title=Seis-ing up the Super-Morrison formation sauropods|journal=Journal of Anatomy|doi=10.1111/joa.14108|pmid=38978276 }}</ref> Mass estimates for the [[Wyoming Dinosaur Center|WDC]] and [[Brigham Young University|BYU]] specimens tend to be around {{convert|35|-|44|MT|ST}} in body mass.<ref name ="Woodruff et al. 2024"/> A potential second species, ''S. lourinhanensis'' (''[[Dinheirosaurus]]''), is known from [[Portugal]] and has been dated to a similar time.<ref name="Tschopp, E. 2015"/>
