How did scientists determine the grass and meat consumption of dinosaurs? Is it accurate?

Through the teeth of dinosaurs, because different dinosaurs, they will evolve different types of teeth in order to adapt to their lifestyle.

Thin, pointed curvilinear teeth generally belonged to carnivorous dinosaurs, such as Tyrannosaurus rex, while herbivorous dinosaurs had the opposite tooth to grind food or a beak to shred leaves. Generally speaking, such a judgment is accurate, after all, only long-term consumption of meat can sharpen the teeth and meet the demand for cutting meat.

Scientists used the teeth of dinosaurs to tell whether they were eating grass or meat, and this method was accurate.

Tooth. Herbivores have different teeth than carnivores, and carnivores have sharper teeth, just like canine teeth, which can be roughly distinguished by this method.

Herbivorous dinosaurs had:

1. Baotousaurus: Baotousaurus is a dinosaur of the order Ornithischianchi, Ankylosaurus, and Ankylosauridae. It is one of the largest dinosaurs in the Ankylosauridae family, similar in size to a small elephant.

It is also the most complete fossil record of the Ankylosaurus suborder, including its spiked armor, low body, and huge club tail.

2. Ceratosaurus: Ceratosaurus is a herbivorous dinosaur that lived in the late Cretaceous period, about 70 million years ago in North America, with a body length of about 8 meters. It has a huge head with an oversized, brightly colored head shield at the back of the head, two large sharp horns above its eyes, and a small horn next to its nose.

Feeding on ferns, cycads, and conifers, the Ceratosaurus was able to bite off and swallow hard leaves or needles with its sharp beak-like mouth.

The weakness of the Baotou Dragon

In order to defend against the attacks of carnivorous dinosaurs, the head and back of Baotou were covered with thick decks, however, such a backup also had blind spots. Their bellies are soft and unprotected, making them a key attack point for carnivorous dinosaurs. It seems that Baotoulong has to find a way to prevent the enemy from turning him over, so that he can protect himself.

1.Herbivorous dinosaurs were creatures that appeared in the Cretaceous period, and their teeth were flat and straight, without serrations, and they were only used for chewing.

2.The shape and size of the teeth of herbivorous dinosaurs depended on the plants they ate.

3.For example, sauropods had spoon-shaped or nail-shaped teeth that made it easy to cut stems and leaves.

4.Because they mainly eat cycads and ferns.

5.The duck-billed dragon mainly eats the stone pine plant horsetail, this plant contains more siliceous and is very hard, so the duck-billed dragon has teeth up and down the left and right sides in its mouth, one is connected to the source of one, densely arranged into many rows, the most can reach more than 2,000, which is an adaptation to eating hard food for a long time.

6.Herbivorous dinosaurus has a small neck and generally walks on four legs.

Summary. Hello, the living habits of herbivorous dinosaurs are: foraging for herbivory food, and like to rest in the jungle.

Hello, the living habits of herbivorous dinosaurs are: foraging for herbivory food, and like to rest in the jungle.

Dinosaurs, with their sturdy limbs, long tails, and huge bodies, lived mainly in the woodlands or open areas of the plains on the shore of lakes, and they have all become extinct on the earth.

Summary. Hello dear, I am happy to answer for you: what is the life habits of the herbivorous kong dragon xing The reply is as follows:

The life habit of the herbivorous dragon is foraging. The plants that herbivorous xingkongsaurs can eat are limited by their height, so some small herbivorous xingkongsaurs will stand on their hind legs in order to eat the leaves of plants in high places. Carnivorous xingkong dragons feed on herbivorous xingkong dragons and other animals.

The different foraging patterns of various Kong dragons are also reflected in their teeth.

Kissing, the skeleton of Kongosaurus had some evolutionary adaptations that would allow them to be distinguished from the original main dragon ancestors. In the later Kongsaurus, these traits underwent more evolutionary changes. The Kong dragon is quite large overall.

By the standard of the Kong dragon, the sauropod is the giant of the round. During the long era of the Burning Dragon, even the smallest sauropods were larger than the rest of their habitat, and the largest sauropods were several levels larger than any other animal that appeared on the surface.
