Diplodocus

Diplodocus is a genus of enormous, long-necked sauropod dinosaurs from Late Jurassic North America, distinguished by an exceptionally long tail and slender, peg-like teeth.

Sauropoda: Sauropoda is the dinosaur clade of large, long-necked, long-tailed herbivores that includes Diplodocus. Diplodocus belongs to this clade, whose shared body plan frames its distinctive proportions.
Sauropod neck: A sauropod neck is the elongated cervical structure supporting the head in long-necked dinosaurs. Diplodocus had an exceptionally long neck, whose flexibility and reach shaped its feeding options.
Othniel Charles Marsh: Othniel Charles Marsh was an American paleontologist who described numerous dinosaur species during the nineteenth century. Marsh named Diplodocus in 1878 from fossils found in Colorado.
Diplodocus longus: Diplodocus longus is the type species of the genus Diplodocus, named from fossils found in Colorado. Its designation anchors the scientific name of the genus.
Apatosaurus: Apatosaurus is a genus of large sauropod dinosaurs from the Late Jurassic Morrison Formation of North America. It shared Diplodocus's habitat but had a more robust build and different vertebrae.
Morrison Formation: The Morrison Formation is a sequence of Late Jurassic sedimentary rocks across western North America, rich in dinosaur fossils. Its rocks preserve many Diplodocus fossils and reveal the environments where the genus lived.
Sauropod tail: A sauropod tail is the elongated posterior extension of the spine, often balancing the body and aiding defense. Diplodocus's whip-like tail may have served as a display or defensive structure.
Bone Wars: The Bone Wars were a late nineteenth-century rivalry between American paleontologists Othniel Charles Marsh and Edward Drinker Cope. The rivalry accelerated fossil collecting and helped bring Diplodocus specimens to scientific attention.
Diplodocus hallorum: Diplodocus hallorum is a species of Diplodocus known from exceptionally large fossils in New Mexico. Its fossil material illustrates the genus's immense size and geographic range.
Barosaurus: Barosaurus is a genus of long-necked sauropod dinosaurs from the Late Jurassic of North America. Its extremely elongated neck offers a close comparison with Diplodocus's proportions.
