Dinosaurs - Triceratops
Triceratops were plant eaters (herbivores) which grazed in large herds together. Triceratops, (genus Triceratops), large quadrupedal plant-eating ceratopsian dinosaur that had a frill of bone at the back of its skull and three prominent horns. Fossils of “three-horned face,” as its Latin name is usually translated, date to the final 3 million years of the Cretaceous Period ( million to million years ago), making it one of the last of the non-avian dinosaurs to have evolved.
Scientists can tell whether a dinosaur was a plant-eater, a meat-eater, or both, by studying its teeth. A Scholastic Professional Book. Although some fans of carnivorous "Tyrannosaurs rex" and "Velociraptor" may find it a what nutrients do strawberries provide disappointing eag the vast majority of dinosaurs were plant-eaters.
Most plant-eating dinosaurs had peg-like or broad, flat teeth designed for snipping or stripping vegetation. While the diet of individual herbivores varied, it likely what do triceratops dinosaurs eat a combination of leaves, twigs, and seeds — found in high treetops or close to the ground. Some plant-eaters, like "Apatosaurus," probably swallowed stones, which settled in their gizzards, helping to grind up the fibrous plant matter they consumed.
These stomach stones, or "gastroliths," are sometimes found among dinosaur bones at dig sites. Then there were the carnivores. These dinosaurs' teeth — long, sharp, and serrated — were designed for tearing through tough meat. The eating habits of individual species no doubt varies, but probably included fellow dinosaurs, lizards, insects, and early mammals. Were the carnivores as fierce as they have been portrayed in the past?
Yes and no. Paleontologists theorize that fast-running meat-eaters, such as "Velociraptor," attacked and killed dinosaurs, then ate them. While others, like the infamous "Tyrannosaurus rex," dhat likely scavengers, feeding on animals that had been killed by other dinosaurs or had died from natural causes. Did any of the dinosaurs eat both plants tricerwtops meat? Fossils show that certain species had different kinds of teeth — some for grinding and others for tearing — which suggests that they may well have feasted on both types of food.
Dinosairs would make these dinosaurs "omnivorous," like us! Guide students through their study of dinosaurs with these articles, lesson what is avr in generator, online learning activities, and writing assignments.

Some Facts – What Types of Omnivore Dinosaurs Are There and How Many?
Aug 04, · Triceratops were herbivorous and probably ate low-growing plants because of their short necks and low heads. They may have eaten bushes, small trees and grasses. They may have been able to eat taller plants by knocking them down with their horns and beaks. Triceratops had anywhere from to teeth arranged in columns of 36 to 40 and stacked three to five teeth high. Although some fans of carnivorous "Tyrannosaurs rex" and "Velociraptor" may find it a bit disappointing — the vast majority of dinosaurs were plant-eaters. Most plant-eating dinosaurs had peg-like or broad, flat teeth designed for snipping or stripping vegetation. While the diet of individual herbivores varied, it likely included a combination of leaves, twigs, and seeds — found in high treetops or close to the ground. Mar 17, · Oddly enough, some of the biggest, fiercest meat-eating dinosaurs of South America and Africa subsisted on sharks, marine reptiles and (mostly) fish.
All living things have to eat in order to survive, and dinosaurs were no exception. Still, you'd be surprised at the specialized diets enjoyed by different dinosaurs, and the sheer variety of live prey and green foliage consumed by the average carnivore or herbivore.
Here's a slideshow of the 10 favorite foods of the dinosaurs of the Mesozoic Era--slides 2 through 6 devoted to meat-eaters, and slides 7 through 11 on the lunch menu of herbivores. Bon appetit! It was a dinosaur-eat-dinosaur world back during the Triassic, Jurassic and Cretaceous periods: large, lumbering theropods like Allosaurus and Carnotaurus made a specialty of chowing down on their fellow herbivores and carnivores, though it's unclear whether certain meat-eaters such as Tyrannosaurus Rex actively hunted their prey or settled for scavenging already-dead carcasses.
We even have evidence that some dinosaurs ate other individuals of their own species, cannibalism not being proscribed by any Mesozoic moral codes! Oddly enough, some of the biggest, fiercest meat-eating dinosaurs of South America and Africa subsisted on sharks, marine reptiles and mostly fish. To judge by its long, narrow, crocodile-like snout and its presumed ability to swim, the largest meat-eating dinosaur that ever lived, Spinosaurus , preferred seafood, as did its close relatives Suchomimus and Baryonyx.
Fish, of course, were also a favorite food source for pterosaurs and marine reptiles--which, while closely related, technically don't count as dinosaurs. Many people are surprised to learn that the earliest mammals lived alongside the dinosaurs; however, they didn't really come into their own until the Cenozoic Era , after the dinosaurs went extinct.
These small, quivering, mouse- and cat-sized furballs featured on the lunch menu of equally petite meat-eating dinosaurs mostly raptors and "dino-birds" , but at least one Cretaceous creature, Repenomamus, is known to have turned the tables: paleontologists have identified the fossilized remains of a dinosaur in this pound mammal's stomach! To date, the direct evidence is scarce for dinosaurs having eaten prehistoric birds or pterosaurs in fact, it's more often the case that larger pterosaurs, like the enormous Quetzalcoatlus , preyed on the smaller dinosaurs of their ecosystem.
Still, there's no question that these flying animals were occasionally munched on by raptors and tyrannosaurs, perhaps not while they were alive, but after they had died of natural causes and plunged to the ground. One can also imagine a less-than-alert Iberomesornis accidentally flying into the mouth of a large theropod, but only once!
Because they weren't equipped to take down larger prey, many of the small, birdlike, feathered theropods of the Mesozoic Era specialized in easy-to-find bugs. One recently discovered dino-bird, Linhenykus , possessed a single claw on each of its forearms, which it presumably used to dig into termite mounds and anthills, and it's likely that burrowing dinosaurs like Oryctodromeus were also insectivorous.
Of course, after a dinosaur died, it was as likely as not to be itself consumed by bugs, at least until a larger scavenger happened on the scene. Way back during the Permian period , to million years ago, cycads were among the first plants to colonize dry land--and these strange, stubby, fernlike "gymnosperms" soon became a favorite food source of the first plant-eating dinosaurs which quickly branched off from the slender, meat-eating dinosaurs that evolved toward the end of the Triassic period.
Some species of cycad have persisted down to the present day, mostly restricted to tropical climates, and surprisingly little changed from their ancient ancestors. Along with cycads see previous slide ginkgoes were among the first plants to colonize the world's continents in the later Paleozoic Era.
During the Jurassic and Cretaceous periods, these foot-high trees grew in thick forests, and helped to spur the evolution of the long-necked sauropod dinosaurs that feasted on them.
Most ginkgoes went extinct at the end of the Pliocene epoch, about two and a half million years ago; today, only one species remains, the medicinally useful and extremely stinky Ginkgo biloba. Ferns--vascular plants lacking seeds and flowers, which reproduce by disseminating spores--were particularly appealing to the low-slung, plant-eating dinosaurs of the Mesozoic Era such as stegosaurs and ankylosaurs , thanks to the simple fact that most species didn't grow very far off the ground.
Unlike their ancient cousins, the cycads and ginkgoes, ferns have prospered in modern times, with over 12, named species around the world today--perhaps it helps that there are no longer any dinosaurs around to eat them!
Along with ginkgoes see slide 8 , conifers were among the first trees to colonize dry land, first popping up toward the end of the Carboniferous period, about million years ago. Today, these cone-bearing trees are represented by such familiar genera as cedars, firs, cypresses and pines; hundreds of millions of years ago, during the Mesozoic Era, conifers were a dietary mainstay of plant-eating dinosaurs, which munched their way through the immense "boreal forests" of the northern hemisphere.
Evolutionarily speaking, flowering plants technically known as angiosperms are a relatively recent development, with the earliest fossilized specimens dating to the late Jurassic period, about million years ago. During the early Cretaceous, angiosperms quickly supplanted cycads and ginkgoes as the main source of nutrition for plant-eating dinosaurs worldwide; at least one genus of duck-billed dinosaur, Brachylophosaurus , is known to have feasted on flowers as well as ferns and conifers.
