Many of the so-called 'dinosaur' remains found on New Zealand are actually mosasaurs and plesiosaurs [citation needed], both being Mesozoic predatory marine reptiles. The largest mosasaur currently on public display is Bruce, a 65-70%-complete specimen of Tylosaurus pembinensis dating from the late Cretaceous Period, approximately 80 million ...
Mosasaurus (/ ˌ m oʊ z ə ˈ s ɔːr ə s /; "lizard of the Meuse River") is the type genus (defining example) of the mosasaurs, an extinct group of aquatic squamate reptiles.It lived from about 82 to 66 million years ago during the Campanian and Maastrichtian stages of the Late Cretaceous.
The belief that plesiosaurs are dinosaurs is a common misconception, and plesiosaurs are often erroneously depicted as dinosaurs in popular culture. [ 141 ] [ 142 ] It has been suggested that legends of sea serpents and modern sightings of supposed monsters in lakes or the sea could be explained by the survival of plesiosaurs into modern times.
Ankylosaurus was the largest-known ankylosaurine dinosaur and possibly the largest ankylosaurid. [12] In 2004 Carpenter estimated that the individual with the largest-known skull (specimen CMN 8880), which is 64.5 cm (2 ft 1.4 in) long and 74.5 cm (2 ft 5.3 in) wide, was about 6.25 m (20 ft 6 in) long and had a hip height of about 1.7 m (5 ft 7 ...
Deinocheirus (/ ˌ d aɪ n oʊ ˈ k aɪ r ə s / DY-no-KY-rəs) is a genus of large ornithomimosaur that lived during the Late Cretaceous around 70 million years ago. In 1965, a pair of large arms, shoulder girdles, and a few other bones of a new dinosaur were first discovered in the Nemegt Formation of Mongolia.
Sea Monsters: A Prehistoric Adventure (also called Sea Monsters) is a 2007 American IMAX 3D documentary film by National Geographic, about prehistoric marine reptiles.It alternates modern-day sequences about the work of scientists studying the animals with computer-animated scenes depicting the prehistoric past.
Dinosaur coloration is generally one of the unknowns in the field of paleontology, as skin pigmentation is nearly always lost during the fossilization process. However, recent studies of feathered dinosaurs and skin impressions have shown the colour of some species can be inferred through the use of melanosomes , the colour-determining pigments ...
Edmontosaurus (/ ɛ d ˌ m ɒ n t ə ˈ s ɔːr ə s / ed-MON-tə-SOR-əs) (meaning "lizard from Edmonton"), with the second species often colloquially and historically known as Anatosaurus or Anatotitan (meaning "duck lizard" and "giant duck"), is a genus of hadrosaurid (duck-billed) dinosaur.
