Knowra Dinosaur renaissance Dinosaur renaissance The dinosaur renaissance was a late twentieth-century shift toward viewing dinosaurs as active, diverse animals and recognizing birds as their living descendants.
John Ostrom : An American paleontologist whose studies of Deinonychus helped recast dinosaurs as active animals. His 1969 description of Deinonychus became a defining challenge to the sluggish-dinosaur model.
Dinosaur locomotion : The ways dinosaurs moved, inferred from fossil skeletons, trackways, and biomechanical analysis. Upright posture and limb mechanics supported depictions of agile, terrestrial animals.
Gregory S. Paul : An American paleoartist and researcher known for influential reconstructions of dinosaurs and other extinct animals. His active, birdlike reconstructions made the revised scientific image visually persuasive.
Feathered dinosaur fossils of Liaoning : Exceptional Cretaceous fossils from northeastern China preserving feathered dinosaurs and other organisms. These discoveries supplied vivid anatomical evidence that the revised view had predicted.
Dinosaurian decline : The historical interpretation that dinosaurs were a biologically stagnant group destined for extinction. The renaissance replaced decline narratives with accounts of ecological diversity and evolutionary success.
Deinonychus : A medium-sized, sickle-clawed theropod dinosaur known from Cretaceous deposits in North America. Its anatomy supplied striking evidence for speed, agility, and predatory behavior.
Endothermy : The production of body heat through internal metabolic processes. Debates about dinosaur activity often turned on whether their physiology supported sustained high energy.
Ostrom–Bakker debate : A scientific exchange over dinosaur activity, physiology, and the implications of their anatomy. The debate helped crystallize the arguments that defined the renaissance.
Archaeopteryx : A Jurassic fossil animal with both dinosaurian and bird-like features, often discussed in studies of bird origins. Its anatomy became newly relevant as dinosaur-bird relationships moved to the center of debate.
Cold-bloodedness : A condition in which body temperature depends substantially on external heat sources. The older reptilian image often assumed dinosaur physiology resembled that of modern ectothermic reptiles.
