Archosaurs Wieland claims to have found stegosaur gastroliths.Wieland (1907). Sanders, Manley, and Carpenter (2001), "Table 12.1" page 167. Brown argues that Wieland's alleged stegosaur gastroliths were "not associated with the stegosaur bones in question." Possible hadrosaur gastroliths documented.Brown (1907). Sanders, Manley, and Carpenter (2001), "Table 12.1" page 167.
