Gravisauria

† Gravisauria — a clade of early sauropod dinosaurs from the Early Jurassic. Includes some of the first massive herbivorous dinosaurs. Heavy-bodied quadrupeds from European, African, and American Jurassic deposits. Ancestral to the later diplodocoid and macronarian sauropod lineages that dominated.

Diet & Feeding

Herbivore

Gravisauria 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 Early Mesozoic Era

Gravisauria lived during the Jurassic Early period of the Mesozoic Era, approximately 201.4 to 174.7 million years ago.

After the Triassic-Jurassic extinction, dinosaurs rapidly diversified and became the dominant land vertebrates. Early sauropods and theropods began to evolve larger body sizes.
