Yutyrannus Dinosaur

Yutyrannus, meaning "feathered tyrant," is one of the largest known dinosaurs to have had feathers. elaborate

Lesothosaurus Dinosaur

Lesothosaurus is considered by some paleontologists to be one of the earliest ornithischian dinosaurs. elaborate

Ouranosaurus Dinosaur

Ouranosaurus's distinctive sail might have been used for thermoregulation, acting like a radiator to both absorb and release heat efficiently. elaborate

Archaeopteryx Dinosaur

Archaeopteryx fossils show evidence of both reptilian teeth and feathered wings. elaborate

Torosaurus Dinosaur

Torosaurus had the largest skull of any known land animal. elaborate

Maiasaura Dinosaur

Maiasaura nests contained eggs arranged in a spiral pattern. elaborate

Minmi Dinosaur

Minmi, a genus of ankylosaurian dinosaur, is notable for having relatively well-preserved skin impressions, showing small osteoderms (bony plates) arranged in rows. elaborate

Hypsilophodon Dinosaur

Hypsilophodon was initially thought to be arboreal (tree-dwelling), a belief later revised based on further fossil discoveries. elaborate

Dreadnoughtus Dinosaur

Dreadnoughtus was so massive that even with a significant portion of its skeleton missing, scientists were still able to estimate its weight. elaborate

Deinocheirus Dinosaur

Deinocheirus's arms were so long that its hands reached past its knees. elaborate

Heterodontosaurus Dinosaur

Heterodontosaurus had different shaped teeth – some like incisors for cropping plants, others like canines for defense, and molars for grinding. This diverse dentition is unique among early ornithischians. elaborate

Polacanthus Dinosaur

Polacanthus had such extensive armor plating that its tail was probably quite stiff and inflexible. elaborate

Euoplocephalus Dinosaur

Euoplocephalus had a club tail that could swing with enough force to break bones. elaborate

Alamosaurus Dinosaur

Alamosaurus, despite its massive size, is believed to have been a relatively fast-growing sauropod. elaborate

Hadrosaurus Dinosaur

Hadrosaurus was the first nearly complete dinosaur skeleton found in North America. elaborate

Austroraptor Dinosaur

Austroraptor, despite being a relatively large dromaeosaurid, had unusually short arms compared to its body size. elaborate

Citipati Dinosaur

Citipati fossils have been found in brooding positions, suggesting they cared for their eggs like modern birds. elaborate

Gigantoraptor Dinosaur

Gigantoraptor, despite its name, wasn't actually a raptor; it was an oviraptorosaur, a group of feathered dinosaurs more closely related to birds. elaborate

Gastonia Dinosaur

Gastonia, North Carolina, is home to the Schiele Museum of Natural History, which boasts a significant collection of mastodon bones. elaborate

Shantungosaurus Dinosaur

Shantungosaurus, despite its massive size, is believed to have been a relatively fast runner for a hadrosaur. elaborate

Oviraptor Dinosaur

Oviraptor's name, meaning "egg thief," is a misnomer. The first fossil was found near a nest of what were assumed to be Protoceratops eggs, but later discoveries showed it was actually sitting on its own eggs. elaborate

Psittacosaurus Dinosaur

Psittacosaurus had a beak similar to a parrot's, but it was likely used for cropping plants rather than cracking nuts. elaborate

Amargasaurus Dinosaur

Amargasaurus had extremely long neck spines that likely supported a pair of skin sails or fleshy humps, unlike any other known sauropod. elaborate

Pachyrhinosaurus Dinosaur

Pachyrhinosaurus had a bony boss on its nose instead of a horn like other ceratopsians. elaborate

Dryosaurus Dinosaur

Dryosaurus had a long, stiff tail that may have been used for balance while running. elaborate
