Dinosaur : any of a group (Dinosauria) of extinct often very large chiefly terrestrial carnivorous or herbivorous reptiles of the Mesozoic era — Merriam-Webster See also OneLook

Encyclopedia

Dinosaurare a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago; their dominance continued through the Jurassic and Cretaceous periods. Reverse genetic engineering and the fossil record both demonstrate that birds are modern feathered dinosaurs, having evolved from earlier theropods during the late Jurassic Period. As such, birds were the only dinosaur lineage to survive the Cretaceous–Paleogene extinction event 66 million years ago. Dinosaurs can therefore be divided into avian dinosaurs, or birds; and non-avian dinosaurs, which are all dinosaurs other than birds. — Wikipedia

Science

Paleontology, also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Body fossils and trace fossils are the principal types of evidence about ancient life, and geochemical evidence has helped to decipher the evolution of life before there were organisms large enough to leave body fossils. Estimating the dates of these remains is essential but difficult: sometimes adjacent rock layers allow radiometric dating, which provides absolute dates that are accurate to within 0.5%, but more often paleontologists have to rely on relative dating by solving the “jigsaw puzzles” of biostratigraphy (arrangement of rock layers from youngest to oldest). — Wikipedia

A spectacular 150-million-year-old trail of more than 130 footprints captures a giant sauropod making a complete loop before continuing on its way. Its uneven stride hints that the long-necked dinosaur may have been walking with a limp.

A 240-million-year-old reptile discovered in Brazil is revealing what evolution looked like just before the rise of dinosaurs and crocodiles. The small predator had unusually positioned legs that may have allowed it to move more efficiently than many earlier reptiles. Its close relatives were previously known mostly from other continents, suggesting these ancient animals spread much farther across the Triassic world than scientists realized.

Dinosaurs conquered the land at enormous sizes, but strangely, they almost never evolved into truly tiny animals. New research suggests that physiology alone can’t explain this missing miniature end of the dinosaur spectrum—and that early mammals may have been partly responsible. While dinosaurs kept mammals from becoming large, small mammals may have returned the favor by occupying ecological niches that could otherwise have supported mouse-sized dinosaurs.

Several enormous Megalodon vertebrae thought to have been destroyed in 1989 were found sitting unnoticed on a museum shelf. Their analysis strengthens evidence that the giant shark could exceed 24 meters (79 feet) in length and live for nearly a century. Researchers also estimate that its newborns may have measured an astonishing 3.6 meters (12 feet).

A spectacular fossil site in Canada contains 567-million-year-old creatures that may represent some of the earliest animals to move, reproduce sexually, and develop recognizable body plans. The discovery pushes key evolutionary milestones back by up to 10 million years and suggests complex animal life may have first flourished in the deep ocean.

Iguanodontians are a diverse group of herbivorous dinosaurs that lived from the Late Jurassic to the Late Cretaceous and had a worldwide distribution. Intercontinental dispersal events between Asia, North America and Europe played a key role in their diversification across Laurasia. Fossils discovered in Japan provide valuable insights into the evolution and biogeography of iguanodontians.

Dinosaurs are famous for being big, from the towering Tyrannosaurus rex to the colossal Apatosaurus. But a new study published today in the journal Evolution by scientists at the American Museum of Natural History and Princeton University suggests that one of the greatest mysteries of dinosaur evolution isn't how some species became giants—it's why even the smallest dinosaurs never became truly tiny.

An international research team led by Assistant Professor Ryuji Takasaki of the Faculty of Biosphere-Geosphere Science at Okayama University of Science has published a paper proposing a new hypothesis on the evolutionary history of dinosaur digestive systems by focusing on gastroliths—stones found within dinosaur abdominal cavities. By examining the degree of wear on these gastroliths, the team sheds light on dinosaur digestion strategies. The findings are published in the journal […]

Recently, a government minister in the Northern Territory, pitching a plan to make Darwin "the data center capital of the globe," suggested it might be a good idea to pump out groundwater to keep Earth's spin steady. If we don't, she said, we might risk "flipping the poles again."
