Dinosaur diets and feeding behavior varied widely throughout the clade, including carnivorous, herbivorous, and omnivorous forms. Ornithopoda. Hadrosauridae
This is a timeline of selected dinosaurs from the list above. Time is measured in Ma , megaannum , along the x-axis. Carnivores are shown in red, herbivores in green and omnivores in blue.
North American herbivorous dinosaurs from this time period include the titanosaur sauropod Alamosaurus, the ceratopsians Bravoceratops, Regaliceratops, Triceratops, Leptoceratops, Torosaurus, Nedoceratops, Tatankaceratops (the latter two possible species of Triceratops), and Ojoceratops, the pachycephalosaurs Pachycephalosaurus, Stygimoloch ...
Tracks were of herbivores and carnivores Four of the track sets were made by sauropods, the giant, long-necked herbivores we generally picture as gentle giants chomping on leaves from tall branches.
In the modern fauna, theropods are represented by over 11,000 species of birds, which are a group of maniraptoran theropods within the clade Avialae.. Theropoda (/ θ ɪəˈr ɒ p ə d ə /; [2] from ancient Greek θηρίο-ποδός [θηρίον, (therion) "wild beast"; πούς, ποδός (pous, podos) "foot"]), commonly known as theropods, is an extant dinosaur clade that is ...
Large meat-eating dinosaurs had a complex system of air sacs similar to those found in modern birds, according to a 2005 investigation led by Patrick M. O'Connor. The lungs of theropod dinosaurs (carnivores that walked on two legs and had bird-like feet) likely pumped air into hollow sacs in their skeletons, as is the case in birds.
The dinosaur's name derives from Chaki, which is a word from the Aonikenk language, of the indigenous Tehuelche people, which means "old guanaco", a reference to a medium-sized herbivore mammal ...
The herbivorous ornithischian dinosaurs were diverse but not as common as sauropods in the Morrison. Fruitadens , previously known as the "Fruita Echinodon ", was found to be a heterodontosaurid . Plate-backed stegosaurids included Hesperosaurus mjosi , Stegosaurus ungulatus , S. stenops , and Alcovasaurus longispinus .
