The London Archaeopteryx, described by Richard Owen in 1863 and held at the Natural History Museum London, was the second specimen recognized and helped establish the genus as a transitional bird-dinosaur.

The Berlin specimen of Archaeopteryx is a Late Jurassic fossil from the Solnhofen limestone of Bavaria and one of the most complete examples of the genus. It preserves a toothed skull, clawed fingers, a long bony tail, and detailed impressions of asymmetrical flight feathers, combining traits associ...

CM 84 is the holotype skeleton of Diplodocus carnegii, a long-necked diplodocid sauropod excavated in Wyoming in 1899 and housed at the Carnegie Museum of Natural History in Pittsburgh.

Elmer S. Riggs was an American paleontologist who worked for the Field Columbian Museum in the early 20th century. In 1903, he named the sauropod dinosaur Brachiosaurus based on fossils found in Colorado. He is also known for his 1903 argument that Brontosaurus was a junior synonym of Apatosaurus. H...

Stegosaurus ungulatus (USNM 4936) is a large stegosaurid from the Late Jurassic Morrison Formation of North America, with specimen USNM 4936 on display at the Smithsonian National Museum of Natural History.

Albert Oppel (1831-1865) was a German paleontologist whose work on Jurassic ammonites revolutionized stratigraphic dating. In his landmark 1856-1858 study, Oppel established the concept of biozones, defining rock layers by specific assemblages of fossil organisms. His meticulous analysis of ammonite...

Allosaurus fragilis is a large theropod dinosaur from the Late Jurassic Morrison Formation of western North America. Othniel Charles Marsh named the species in 1877, and numerous skeletons have since made Allosaurus one of the better documented large Jurassic predators. USNM 4734 is a historically i...

Megalosaurus bucklandii was a large carnivorous theropod dinosaur that lived during the Middle Jurassic in what is now England. William Buckland formally described Megalosaurus in 1824 from fossils found in Oxfordshire, making it the first non-avian dinosaur to receive a valid scientific name. The k...

FMNH P25107 is the holotype specimen of Brachiosaurus altithorax, a large sauropod dinosaur from the Late Jurassic Morrison Formation of Colorado. Elmer Riggs and his field team collected the partial skeleton in 1900, and Riggs named the species in 1903. The specimen, held by Chicago's Field Museum,...

Dinosaur National Monument is a protected area spanning northeastern Utah and northwestern Colorado, established in 1915 around a major dinosaur fossil quarry. At the Quarry Exhibit Hall, visitors can see more than 1,500 dinosaur bones preserved in an exposed rock face, including remains of large Ju...

Anchiornis huxleyi, a Late Jurassic troodontid from China, was the first dinosaur to have its feather coloration scientifically reconstructed via melanosome analysis, revealing a black-and-white speckled pattern with a red crown.

Peter Galton was a paleontologist whose work focused extensively on basal ornithischians and sauropodomorphs, two groups central to the study of dinosaur evolution. His research reassessed the anatomy, relationships, and classification of early dinosaurs and their relatives, with revisions appearing...

Werner Janensch (1878–1969) was a German paleontologist best known for leading the German Tendaguru Expeditions in what is now Tanzania between 1909 and 1913. These expeditions recovered enormous quantities of Late Jurassic dinosaur fossils, including the holotype of Brachiosaurus brancai, which Jan...

Rhamphorhynchus muensteri was a long-tailed pterosaur that lived in Europe during the Late Jurassic. Many specimens come from the fine-grained Solnhofen limestone of Germany, where exceptional preservation sometimes records wing membranes, a diamond-shaped tail vane, and stomach contents. Its elonga...

His research addresses the evolution, morphology, taxonomy, and fossil record of turtles, including the Late Jurassic turtle Solnhofia and questions about the ori...

Jonah N. Choiniere is a vertebrate paleontologist and Professor of Comparative Palaeobiology at the Evolutionary Studies Institute, University of the Witwatersrand, Johannesburg. His research concerns dinosaur evolution, especially theropods and their evolutionary relationships, and includes the des...

Supersaurus vivianae is a diplodocid sauropod dinosaur from the Late Jurassic Morrison Formation of western North America. The specimen associated with the catalog number BYU 9025 was recovered from the Dry Mesa Dinosaur Quarry in Colorado and contributed to the genus's scientific description in 198...

STM 31-2 is the holotype fossil of Yi qi, a small scansoriopterygid dinosaur from Late Jurassic rocks in Hebei, China, described in 2015.
