By extension, all Ceratopsids had a shearing dentition and efficient, powerful jaw mechanics that allowed them to feed on tough vegetation. Mallon and Anderson postulated that Ankylosaurs and Ceratopsids may have partitioned the herb layer in the Dinosaur Park Formation, or that Ceratopsid feeding height was slightly higher. [21]
Mounted skeletons of different age groups, Los Angeles Natural History Museum. The feeding behaviour of Tyrannosaurus rex has been studied extensively. The well known attributes of T. rex (its jaws, legs and overall body design) are often interpreted to be indicative of either a predatory or scavenging lifestyle, and as such the biomechanics, feeding strategies and diet of Tyrannosaurus have ...
Parasaurolophus, a crested hadrosaur.. Hadrosaurids, also commonly referred to as duck-billed dinosaurs or hadrosaurs, were large terrestrial herbivores.The diet of hadrosaurid dinosaurs remains a subject of debate among paleontologists, especially regarding whether hadrosaurids were grazers who fed on vegetation close to the ground, or browsers who ate higher-growing leaves and twigs.
Scientists say this difference in feeding mechanisms ‘set them up to dominate life on land for millions of years to come’.
Scientists believe they may have uncovered the first known incident of a mammal being eaten by a dinosaur. Palaeontologists in the UK have analysed fossil remains from around 120 million years ago ...
Like all sauropods, Nigersaurus was a quadruped with a small head, thick hind legs, and a prominent tail. Among that clade, Nigersaurus was fairly small, with a body length of only 9 m (30 ft) and a femur reaching only 1 m (3 ft 3 in); it may have weighed around 1.9–4 t (2.1–4.4 short tons), comparable to a modern elephant.
"Most crocodilians feed at the surface of the water and are ambush predators, and many pterosaur species are thought to be tied to the water as well. ... armored dinosaurs, meat-eating dinosaurs ...
Dryosaurus (/ ˌ d r aɪ ə ˈ s ɔːr ə s / DRY-ə-SOR-əs, meaning 'tree lizard', Greek δρῦς (drys) meaning 'tree, oak' and σαυρος (sauros) meaning 'lizard'; the name reflects the forested habitat, not a vague oak-leaf shape of its cheek teeth as is sometimes assumed) is a genus of an ornithopod dinosaur that lived in the Late Jurassic period.
