Dinosaur knowledge introduction PPT directory and content introduction:

1. Classification of dinosaurs

Scientists divide them into two major categories based on the shape of their bone fossils:

Ornithosaurs, sauropods

Based on their tooth fossils, it can also be inferred whether they were carnivorous or herbivorous.

We discovered that there are not only many types of dinosaurs, but also their shapes are all strange. Some of these dinosaurs fly in the sky, some swim in the water, and some crawl on land. Let’s get to know them briefly.

Tyrannosaurus rex, also known as Tyrannosaurus rex, is a large carnivorous dinosaur with a length of about 14 meters and a weight of about 6.8 tons. It has a strong body, a not too long tail, short forelimbs and strong and thick hind limbs.

Stegosaurus is a huge herbivorous dinosaur. It has a row of huge bony plates on its back and a dangerous tail with four spikes to defend itself from predators. It can reach approximately 12 meters long and 7 meters high, and can weigh up to 4 tons. The whole body was like the current elephant, but it only had a pitifully small head.

2. Extend learning

Ctenosaurus

There are eye-catching tubes on the head with thin channels inside. It emits a low sound as the air passes through it, which can be used to scare away enemies. Some people also believe that they are used for ventilation during diving, but there is currently no conclusion.

Protoceratops

When Protoceratops lays eggs, several females often share a nest, and they take turns laying eggs in circles. It seems that they are very united.

Allosaurus

A ferocious and terrifying carnivorous dinosaur with a mouth so big it could swallow a piglet in one go. Its teeth are all curved inward, and the prey cannot escape if it bites it.

3. The extinction of dinosaurs

Dinosaurs lived on earth for more than 100 million years

About 65 million years ago, this animal suddenly and mysteriously disappeared. what is the reason behind the scene? Humanity has yet to solve this mystery.

The climate environment made the dinosaurs extinct. Starting from the Cretaceous Period, the environment and climate on the earth have changed. A climate with four distinct seasons has appeared. The two poles have become colder. The plants that dinosaurs like to eat cannot adapt to such a climate and have become extinct.

Thickening of dinosaur eggshells led to the extinction of dinosaurs.

Scientists' research shows that dinosaur eggshells in the late Cretaceous became thicker and could not hatch baby dinosaurs.

An asteroid hit the earth and wiped out the dinosaurs. 65 million years ago, an asteroid with a diameter of 10 kilometers hit the earth, leaving the earth in darkness for three months. The dinosaurs could not find food and became extinct.
