Taxonomy
Amphicoelias fragillimus was named by Cope (1878). Its type specimen is AMNH FR 5777 (lost), a set of vertebrae (Dorsal neural arch, femur), and it is a 3D body fossil. Its type locality is Cope Quarry III, Cope's Nipple, which is in a Tithonian dry floodplain mudstone in the Morrison Formation of Colorado.
It was synonymized subjectively with Amphicoelias altus by McIntosh (1990), Upchurch et al. (2004) and Woodruff and Foster (2014); it was considered a nomen dubium by Osborn and Mook (1919); it was recombined as Maraapunisaurus fragillimus by Carpenter (2018).
