Plant-eating dinosaurs are called herbivores, a Neo-Latin term that literally means "herb eater." Long-necked, herbivorous dinosaurs reach high into trees to eat green leaves and fruits, while the short-necked dinosaurs graze on grass and other low-lying vegetation. Herbivores are preyed upon by carnivorous dinosaurs, such as Tyrannosaurus Rex.Continue Reading
Herbivorous dinosaurs first appeared during the Late Triassic period and died at the end of the Cretaceous period, which spanned from approximately 230 million to 65 million years ago, respectively. Herbivorous dinosaurs include such species as Stegosaurus, Triceratops, Brontosaurus and Brachiosaurus.
Approximately 700 different species of carnivorous, herbivorous and omnivorous dinosaurs have been discovered and named by palaeontologists.Learn more about Dinosaurs
The largest carnivore to ever walk the earth was Spinosaurus, the largest of the dinosaurs, while the largest living carnivore is the male Southern elephant seal. Although fossil records are not sufficiently complete to determine a precise size, experts estimate that the Spinosaurus grew to 59 feet long and weighed as much as 9.9 tons. The largest bull Southern elephant seal was 22.5 feet long and weighed 11,000 pounds.Full Answer >
The first true dinosaurs first appeared about 230 million years ago. The first dinosaur fossils are distinguished from those of their reptile ancestors by their more upright stance, with legs directly beneath the body instead of splayed to the side, as with other reptiles. The earliest dinosaur fossils were found in South America, although a December 2012 fossil discovery in southern Africa casts some doubt on a South American origin.Full Answer >
True dinosaurs were not swimmers. There were a number of very large aquatic reptiles that lived during the age of the dinosaur, but they were not technically dinosaurs. These creatures belonged to one of several other groups, such as ichthyosaurs, plesiosaurs and mosasaurs, which were types of marine reptiles.Full Answer >
There are numerous theories regarding the extinction of the dinosaurs, including the triceratops, at the end of the Cretaceous period. The most prevalent theory describes the sudden destruction of the dinosaurs, and 50 to 75 percent of the planet's flora and other fauna, being due to a huge asteroid impact that dramatically altered the environment. However, despite strong evidence, there is no conclusive proof, explains the Smithsonian Institution.Full Answer >
