In 1975 Wiffen discovered the first dinosaur fossils in New Zealand in the Mangahouanga Valley in Northern Hawkes Bay. Her first discovery was the tail bone of a theropod dinosaur. Her later finds included bones from a hypsilophodont , a pterosaur , an ankylosaur , mosasaurs and plesiosaurs . [ 2 ]
Supersaurus (meaning "super lizard") is a genus of diplodocid sauropod dinosaur that lived in North America during the Late Jurassic period. The type species, S. vivianae, was first discovered by Vivian Jones of Delta, Colorado, in the middle Morrison Formation of Colorado in 1972.
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 university said in one area of the quarry, the tracks of the carnivore and herbivore dinosaurs crossed paths, leaving researchers to wonder how and if the two dinosaur species may have interacted.
Caudipteryx (meaning "tail feather") is a genus of small oviraptorosaur dinosaurs that lived in Asia during the Early Cretaceous, around 124.6 million years ago.They were feathered and extremely birdlike in their overall appearance, to the point that some paleontologists suggested it was a bird.
The bird-like features of these species, along with other dinosaurs such as Archaeopteryx inspired the idea for the connection between dinosaur reptiles and modern-day avian species. [4] Compsognathid fossils preserve diverse integument — skin impressions are known from four genera commonly placed in the group, Compsognathus , Sinosauropteryx ...
The complete right humerus measured 1.69 meters (5.5 feet) long which at the time of discovery was the longest known in a Cretaceous sauropod; this was surpassed in 2016 with the discovery of Notocolossus which had a 1.76 m (5 ft 9 in) humerus. [7] Using Saltasaurus as a guide, Carpenter estimated its length at around 26 m (85 ft) in 2006. [8]
Other dinosaurs from these formations include the heterodontosaurid Heterodontosaurus, the basal sauropodomorph Massospondylus, and the theropod Megapnosaurus. The Upper Elliot Formation shows the largest known heterodontosaurid diversity of any rock unit; besides Heterodontosaurus , it contained Lycorhinus , Abrictosaurus , and Pegomastax .
