Knowra Sauropoda Sauropoda Sauropoda is a clade of long-necked, usually herbivorous dinosaurs with small heads, column-like limbs, and massive bodies. It includes the largest known land animals.
Dinosauria : Dinosauria is the group of reptiles that includes birds and all extinct dinosaurs. Sauropoda is one major dinosaur lineage, distinct from theropods and ornithischians.
Gigantism : Gigantism is the evolution of body sizes far larger than those of related organisms. Sauropod gigantism required coordinated changes in skeleton, metabolism, feeding, and reproduction.
Diplodocus : Diplodocus is a long-tailed sauropod dinosaur known from Late Jurassic deposits in western North America. Its exceptionally long neck and whip-like tail exemplify one distinctive sauropod body plan.
Plateosaurus : Plateosaurus is a large, bipedal or facultatively quadrupedal sauropodomorph from the Late Triassic. It illustrates the varied body forms among relatives that preceded true sauropods.
Mesozoic : The Mesozoic Era is the geological era from about 252 to 66 million years ago, encompassing the Triassic, Jurassic, and Cretaceous periods. Sauropods were major terrestrial herbivores throughout much of this dinosaur-dominated era.
Sauropodomorpha : Sauropodomorpha is the dinosaur group containing sauropods and their closest relatives. It places Sauropoda within a broader lineage that includes earlier, often smaller forms.
Sauropod neck evolution : Sauropod neck evolution is the diversification of neck length, structure, and function across the clade. Long necks expanded feeding reach while vertebral design helped keep them manageable.
Brachiosaurus : Brachiosaurus is a large, high-shouldered sauropod dinosaur from the Late Jurassic of North America. Its elevated forequarters and long forelimbs contrast with the more level bodies of many sauropods.
Antetonitrus : Antetonitrus is an early sauropodomorph from the Late Triassic of South Africa, showing adaptations for supporting great weight. Its anatomy documents an early stage in the evolution of sauropod-like weight-bearing.
Herbivory : Herbivory is the consumption of plants or plant parts by animals. Sauropods’ plant-eating shaped their teeth, digestive demands, and interactions with vegetation.
