Supersaurus

† Supersaurus is a Late Jurassic diplodocid sauropod from the Morrison Formation of the United States, one of the longest known dinosaurs. Its estimated length exceeds 33 meters, making it a contender for the longest terrestrial animal ever to have lived.

Diet & Feeding

Herbivore

Supersaurus 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

Supersaurus 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.
