Maraapunisaurus is a genus of sauropod dinosaur from the Late Jurassic Morrison Formation of western North America. Originally named Amphicoelias fragillimus, it has sometimes been estimated to be the largest dinosaur specimen ever discovered.
Based on the Late Jurassic Maraapunisaurus 64, a North American origin of rebbachisaurids and their dispersal into South America through Europe and Africa during the latest Jurassic–earliest ...
Maraapunisaurus (Amphicoelias) fragillimus. Cope named a third species of Amphicoelias from a nearby locality (Cope Quarry III) the following year. Based only on a middle–posterior dorsal neural arch (AMNH FARB 5777), Cope erected A. fragillimus.
Maraapunisaurus fragillimus is a genus of sauropod dinosaur that, if confirmed, would rank among the largest terrestrial animals to have ever existed. Discovered in the Late Jurassic Morrison Formation, approximately 149-145 million years ago, Maraapunisaurus is known from very fragmentary remains and has sparked significant debate regarding ...
Reanalysis of Cope's publication in light of other sauropods discovered since 1878 indicates that Amphicoelias fragillimus is a basal rebbachisaurid characterized by pneumatic neural spine and ...
Maraapunisaurus fragillimus, N.G. (formerly Amphicoelias fragillimus), a basal Rebbachisaurid from the Morrison Formation (Upper Jurassic) of Colorado. Kenneth Carpenter Prehistoric Museum, Utah State University Eastern. DOI: https://doi.org/10.31711/giw.v5.pp227-244.
The earliest record of this clade is Maraapunisaurus, now dated as Upper Jurassic of North America (Morrison Formation) (Carpenter, 2018). Moreover, the Lower Cretaceous Xenoposeidon from...
Maraapunisaurus is a genus of sauropod dinosaur from the Late Jurassic Morrison Formation of western North America. It is known only from what has sometimes been estimated to be the largest dinosaur specimen ever discovered, originally named Amphicoelias fragillimus .
Maraapunisaurus Fragillimus was longer than a blue whale, the largest animal currently living on Earth. - At its largest estimated size, it was almost as long as two basketball courts placed end to end. - Even using smaller estimates, it was as long as three school buses lined up.
