Amphicoelias brontodiplodocus

†Amphicoelias brontodiplodocus is a controversial sauropod species proposed by Galiano and Albersdörfer in 2010 based on material from the Morrison Formation. Most paleontologists consider it a nomen dubium or a synonym of other Morrison sauropods such as †Diplodocus or †Brontosaurus. The material does not display unique diagnostic features sufficient to support a distinct species designation.

Diet & Feeding

Herbivore

Amphicoelias brontodiplodocus was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Jurassic Late Mesozoic Era

Amphicoelias brontodiplodocus lived during the Jurassic Late period of the Mesozoic Era, approximately 161,5 to 145,0 million years ago.

One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
