Info

Diplodocus (Marsh, 1878) > Diplodocus longus (Marsh, 1878) Diplodocus carnegii (Hatcher, 1901) Diplodocus hayi (Holland, 1924) Diplodocus lacustris (Marsh, 1884)

Diplodocus (Marsh, 1878) > Diplodocus halli (Lucas, Spielmann, Rinehart, Heckert, Herne, Hunt, Foster, and Sullivan, 2006) >> Seismosaurus halli (Gillette, 1991) > Diplodocus hallorum {misspelled} (Lucas, Spielmann, Rinehart, Heckert, Herne, Hunt, Foster, and Sullivan, 2006) Seismosaurus hallorum {misspelled} (Gillette, 1991)

Seismosaurus halli was formally and properly published by Gillette in 1991. George Olschevsky corrected his use of the singular form to the plural, a correction to which Dave Gillette readily agreed. However, according to ICZN rules, there was no valid grounds by which that change was made, so S. hallorum must be considered a junior synonym of S. halli. In 2006, Lucas, et. al., declared that there were no significant character differences between Seismosaurus and Diplodocus, and renamed S. hallorum D. hallorum. As previously mentioned, the use of hallorum violates ICZN rules, so Lucas\\\' revision must be considered D. halli. [source: David Trexler]
