Plant- Eating Dinosaurs and their lifestyles: Surprising Lifestyle of Dinosaur

Plant- eating dinosaurs are surprising to hear and learn about due to their actions towards plants and weeds. Probably two- thirds of all dinosaurs were plant eaters. During the Mesozoic Era- the time dinosaurs walked the earth- the type of plants available to eat changed a lot. Dinosaurs dynastic rose and fell according to the plants they ate. As one type of plant of plant became rare, so the dinosaurs that ate it starved. As another plant took hold and spread around the land, so the dinosaurs that ate became more numerous. At the beginning of the Mesozoic Era the most common plants were conifers such as redwoods and pines and horse- tails and cycads. Their leaves and seeds were low in calories and difficult to digest. But by the Cretaceous Period, flowering plants such as sycamores, magnolias and laurels had appeared and thrived. These were much more nutritious and grew in much greater numbers. The availability of such a rich supply of food meant that in the Cretaceous Period that were more dinosaurs than ever before.

Each type of plant- eating dinosaurs had its own way of feeding and dealing with the meat eaters that preyed upon it. The biggest dinosaurs ever were plant eaters. Unlike most meat eaters, many plant eaters walked on four. Teeth were usually flat; to strip and chew the plant ate.

Plant- Eating Dinosaurs and their lifestyles: Food Chain and Early herds:

Without plants there would have been no plant- eating dinosaurs. Without them, the meat eaters would have had nothing to eat, either. This process is called a food chain and the panel shows an example of one.

Plateosaurs was one of the earliest known plant eating dinosaurs. It travelled in large herds, searching for conifers and ferns in Europe during the late Triassic Period. Its long neck helped it to reach the leaves that smaller plant eaters left behind. It could probably rare up on its back legs to nibble even higher. It had sharp teeth to break up the tough leaves it ate and probably swallowed stones to help it grind up the food in its stomach. Plateosaurus had small claws on its limbs, but its remain defense against predators was probably its huge size- it grew to around 7 meters (23 feet).

Plant- Eating Dinosaurs and their lifestyles: Reaching for the Sky and Beak Face.

The Tallest dinosaur found so far was Brachiosaurus. Towering at about 12.5 meters above the ground, Brachiosaurus ate from the tops of tall trees, pulling off leaves with its 52 chisel- shaped teeth. It swallowed its food without chewing, leaving the entire process of digestion to its massive gut. It belonged to an order of dinosaurs called sauropods- the largest land animal to have ever lived. Its fossils remains, dating from the late Jurassic Period, have been found in North America and Africa. Unlike most plant eaters, whose lives were constantly threatened by meat- eating predators, the Brachiosaurs could probably graze in peace, as it was well over twice the size of the largest predator around.

Triceratops was a type of dinosaurs called a ceratopsian, meaning ‘one with a horn’. Such dinosaur existed towards the end of the cretaceous Period. They lived in much of North America and central Asia. Ceraptopsians owed their success to the way they ate. With a sharp, parrot- shaped beak of a mouth, chopping teeth and powerful jaws, they could even the toughest plants. They chew their food, too making it easier to digest. Like many plant eaters, trice raptors was probably a herd animal. It may have travelled large distances in search of food. Trice raptors had a huge skull, with three horns and a bony neck plate. These were greatest defense against meat eaters. But even its size could not frighten off its chief enemy, tyrannosaurus rex.

Plant- Eating Dinosaurs and their lifestyles: Suit of Armor and Spikes and Plates.

Some plant eaters were heavily armored. Saichana was built like a tank. It was a type of plant eater called an ankylosaur. This one lived around Mongolia during the late cretaceous Period. Saichana’s low stooping posture suggests it was a grazer and it probably nibbled at grasses and bushes with its beak- like mouth. It had a bony plate inside its mouth which allowed it to chew up even the toughest plats. As well as their fearsome set of body armor, ankylosaurus also had a lethal bony club on the end of their tail to protect them from attackers. The armor must have worked as ankylosaurs were numerous around North America and East Asia.

Other plant eaters had different forms of defense. Stegosaurus had its own building protection. Its bony back plates were probably too fragile to act effectively as armor, but the spikes on its tail could have been very useful against any attacker. Stegosaurus lived in North America I the late Jurassic Period. They weighed 2 tones and were about 6 meters long. Usually, their back legs were twice as long as their back legs, so their heads sloped forwards towards the ground. He back legs were probably strong enough to allow stegosaurus to rear up to feed on tree branches. Stegosaurus had a toothless beak at the front of its jaw, with small chewing teeth at the back, to help it mash up the tough ferns, mosses and conifers it ate.

Plant- Eating Dinosaurs and their lifestyles: New Teeth Of Old.

One group of dinosaurs, called hadrosaurs, had no teeth at the front of their mouth, but had rows of check teeth in their upper and lower jaws. Old teeth, worn out by endlessly chewing a touch plant diet, were continually replaced by new ones. No other type of dinosaurs had this natural advantage, and it helped the hadrosaurs become some of the most common, successful dinosaurs of their time. Hypacrosarus was a 9 meter (30 foot) long hadrosaur and it grazed in herds in the forests of North America, during the late cretaceous Period. It probably moved on all fours as it searched for pine needles, fruit and magnolia leaves. But unlike most other plant eaters, if threatened it could run away at some speed on its powerful back legs. Hypacrosaurus ate all sorts of plants, as the period it lived in saw a huge spread in plant life across the globe. Their success as a species in plants eaters, such as Iguanodon and giant sauropods such as Brachiosaurus, which were too slow to compete with them.
