Diplodocidae

†Diplodocidae is the extinct family of sauropod dinosaurs including Diplodocus, Apatosaurus, and Brontosaurus, from the Late Jurassic Morrison Formation of North America and equivalent strata elsewhere. These enormous herbivores reached 25–30 m in length, bearing extremely long necks and whip-like tails. Diplodocids are among the most iconic and extensively studied dinosaurs.

Diet & Feeding

Herbivore

Diplodocidae 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

Diplodocidae 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.
