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] As well as suggesting that the Ornithopods might have made room for the passing Ceratopsid herds by rising up to avoid ecological competition.
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.
Gastroliths have often been described as important for sauropod dinosaurs, whose diet of vegetation required very thorough digestion, but Wings concluded that this idea was incorrect: gastroliths are found with only a small percentage of sauropod fossils; where they have been found, the amounts are too small and in many cases the stones are too ...
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 ...
Tyrannosaurus (/ t ɪ ˌ r æ n ə ˈ s ɔː r ə s, t aɪ-/) [a] is a genus of large theropod dinosaur.The type species Tyrannosaurus rex (rex meaning 'king' in Latin), often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods.
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.

They suggested that behavior, diet, soil condition, and competition between dinosaur species all potentially influenced where hadrosaurs nested. [41] Sub-centimeter fragments of pebbly-textured hadrosaur eggshell have been reported from the Dinosaur Park Formation.
