14 numerous differences in the construction of the vertebra also noted by Cope, and suggested these differences are enough to warrant a separate species or even a separate genus for Amphicoelias fragillimus. However, he went on to caution that the validity of Amphicoelias fragillimus as a separate species is nearly impossible to determine without the original specimen to study (Wikipedia). In 2007, John Foster suggested that the differences usually cited to differentiate Amphicoelias altus from the more well-known Diplodocus are not significant and may be due to individual variation. Foster argued that Amphicoelias is probably the senior synonym of Diplodocus, and that if further research bears this out, the familiar name Diplodocus would need to be abandoned in favor of Amphicoelias, as was the case with Brontosaurus and its senior synonym Apatosaurus (Wikipedia).
