There are dinosaurs in all three categories. Dinosaurs were an incredibly diverse group of animals. However, there are far fewer varieties of dinosaur omnivores than either herbivores or carnivores.
For example:
Two Herbivorous Dinosaurs: Triceratops and Ankylosaurus
Two Carnivorous Dinosaurs: Tyrannosaurus Rex and Allosaurus
Two Omnivorous Dinosaurs: Ornithomimus and Heterodontosaurus
There are mammals in every category. Being a mammal does not define if it is a carnivore (canids and felids), omnivore (humans and some other primates, some bears) or herbivore (sheep, cattle, antelope, rabbits).
not all dinosaurs were carnivoresSome Dinosaurs were carnivors, but most were herbivores or omnivores.
omnivores ,herbivores and carnivores
Invertebrates can be herbivores, carnivores or omnivores. Caterpillars are herbivores, for example, while spiders are carnivores.
They are mostly herbivores. Some are carnivores Some are omnivores Some are herbivores
There are three dietary groups that dinosaurs can go into: herbivores (plant eaters), carnivores (meat eaters), and omnivores (dinosaurs that ate both plants and animals). Herbivores include Apatosaurus, Stegosaurus, and Triceratops. Carnivores include T-rex, Allosaurus, and Velociraptor. Omnivores included Oviraptors and Ornithomimosaurs.
