The physiology of dinosaurs has historically been a controversial subject, particularly their thermoregulation.Recently, many new lines of evidence have been brought to bear on dinosaur physiology generally, including not only metabolic systems and thermoregulation, but on respiratory and cardiovascular systems as well.
The enduring popularity of dinosaurs, in its turn, has resulted in significant public funding for dinosaur science, and has frequently spurred new discoveries. In the United States, for example, the competition between museums for public attention led directly to the Bone Wars of the 1880s and 1890s, during which a pair of feuding ...
Dinosaur bones weren’t exactly new discoveries, but the explanations were. Many of the same bones that Buckland imagined as belonging to a megalosaurus had been found in the 17th century ...
Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria." [1] In 1887 and 1888 Harry Seeley divided dinosaurs into the two orders Saurischia and Ornithischia, based on their hip structure. [2]
John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American paleontologist who revolutionized the modern understanding of dinosaurs. [1] Ostrom's work inspired what his pupil Robert T. Bakker has termed a "dinosaur renaissance".
The simplest definition of "paleontology" is "the study of ancient life". [5] The field seeks information about several aspects of past organisms: "their identity and origin, their environment and evolution, and what they can tell us about the Earth's organic and inorganic past".
The term "dinosaur" is sometimes used mistakenly to describe other prehistoric animals, such as the synapsid Dimetrodon, or reptiles like pterosaurs, ichthyosaurs, plesiosaurs and mosasaurs. Since the first dinosaur fossils were recognized in the nineteenth century, mounted dinosaur skeletons have become major attractions at museums around the ...
