Herbivores Herbivores or plant-eating dinosaurs lived during the Mesozoic era Most dinosaurs were plant eaters but the largest are called sauropods They died out 65 million years ago but their fossils tell us these huge creatures were the biggest land animals to ever live They weighed as much as 100 tons 91 metric tons They stood more than 40 feet 12 m tall twice as tall as a giraffe At 130 feet 40 m in length they were as long as two bowling alley lanes Their massive size and strong muscles allowed them to live on Earth for 150 million years
XTREME FACT Sauropods were one of the most successful species to live on Earth Their fossil remains have been found on every continent on the planet including Antarctica
Teeth Sauropods had teeth made for eating plants Some herbivores had spatula-shaped teeth that allowed them to eat tough vegetation Others had peg-like teeth that they used to rake the leaves off trees Seismosaurus Earthquake Lizard with peg-like teeth
Herbivores may not have chewed their food They likely swallowed plants whole and allowed their massive stomachs to digest their meals over many days XTREME FACT Sauropods had an unlimited supply of replacement teeth Some species grew a new tooth every two weeks while others replaced each tooth every two months
