Diplodocoidea

†Diplodocoidea is a major clade of neosauropodan dinosaurs uniting Rebbachisauridae, Dicraeosauridae, and Diplodocidae. Ranging from Late Jurassic to Early Cretaceous on all inhabited continents, these herbivores adapted low-browsing strategies using elongated, low-set necks. The clade represents the most diverse lineage of long-necked plant-eating dinosaurs known globally.

Diet & Feeding

Herbivore

Diplodocoidea 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

Cretaceous Early Mesozoic Era

Diplodocoidea lived during the Cretaceous Early period of the Mesozoic Era, approximately 145.0 to 100.5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
