Pronunciation: KWET-zal-KO-at-lus

Meaning: the snake god in feathers

Size: Span 10 to12m.

Weight: 100 kg

Date: Late Cretaceous, 65 million years ago.

Location of discovery: USA

The largest flying animal to date.

Its wingspan is equivalent to a fighter plane.

Named after Quetzalcoatl, Aztec Quetzalcoatl.

Pterosaur may not have feathers, but it is by far the largest flying animal. Its wings are similar to bats, and its skeleton is covered with a layer of wing membrane as thick as tissue paper. When fully unfolded, its wingspan can reach 12 meters.

This pterosaur moved slowly and clumsily on land, but it was very good at flying long distances in the warm current over the Cretaceous landform.

Paleontologists have different opinions about the food source of pterosaurs. Some people think it eats shellfish and crustaceans with its long beak, while others think it preys on marine fish like other pterosaurs.

Name: Archaeopteryx

Pronunciation: ark -e-OP-ter-ticks

Meaning: ancient wings

Body shape: 30 cm tall and 90 cm long.

Weight: about 900g

Date: Late Jurassic,1.500 million years ago.

Place of discovery: Germany

It is considered to be the earliest known bird.

There are only seven existing bone fossils.

Are found in the Sorenhofen rock layer in Bavaria, Germany.

Archaeopteryx was discovered in a quarry in Germany in 186 1 year. Since then, only a few other samples have been found-all in Bavaria, Germany.

However, these rare and peculiar fossils are quite well preserved and are one of the most important fossils discovered so far.

Archaeopteryx has claws on its forelimbs, wings on the outside, a slender tail and long sharp teeth, all of which are the characteristics of reptiles. But its feather fossils strongly prove the connection between dinosaurs and modern birds.

Tyrannosaurus Rex and Brachiosaurus

Name: Tyrannosaurus Rex

Pronunciation: iron-natural-oh-saw -RUS

Meaning: Tyrant-like dinosaur

Body type: length14.6m, height 5m.

Weight: 5 tons

Age: Late Cretaceous (67 million to 65 million years ago)

Discovery: Canada, USA, Mongolia

The mouth is big enough to bite the front of the car.

Full of fangs, teeth as big as a human head.

Can swallow a family of four shopping for a week.

Tyrannosaurus rex is the most terrible dinosaur ever. However, experts still disagree about whether this terrible carnivore is a predator or a scavenger.

The revisionists believe that Tyrannosaurus Rex's eyesight is extremely poor and its forelimbs are very short, which can be compensated by its keen sense of smell. Strong hind legs enabled Tyrannosaurus Rex to track the smell of carrion miles away.

Its terrible shape makes it invincible and has no rivals.

Name: Brachiosaurus

Pronunciation: brake-ee-o-sawr-us

Meaning: a dinosaur with long arms

Body shape: 30 meters long, height 15 meters.

Weight: 70 tons

Time: Late Jurassic (1.500 million to 1.25 million years ago)

Location of discovery: United States, Tanzania

Elephants weighing more than twenty.

A building with more than three floors.

Each cervical vertebra is one meter long.

Brachiosaurus was discovered in Colorado in 1900. It is one of the largest animals ever. It stands ten times as tall as human beings.

This gentle beast has a slender head and neck and is very suitable for feeding tall plants in the late Jurassic, just like giraffes.

Brachiosaurus belongs to sauropod dinosaur. There were many sauropods in Jurassic, but they all disappeared about 1 100 million years ago. The most complete brachiosaurus skeleton was found in Tandagulu, Tanzania.

Submarine killer

Name: Hailong

Pronunciation: Hai-Nuo -SAWR- America

Meaning: Reptiles of Ain River.

Body shape: the body length can reach 17m.

Weight: 20 tons

Age: Late Cretaceous, 85 million to 65 million years ago.

Location of discovery: Belgium and France

It is almost twice as long as a London bus.

The weight is equivalent to four elephants.

Strong enough to attack prehistoric sharks twice the size of great white sharks.

Black dragon was a very successful marine predator in the late Cretaceous, living in the oceans all over the world. Ainalon is the largest black dragon. These killers have nothing to fear-except other ion dragons.

Ainalong couldn't swim fast, so she had to sneak up to catch prey. They mainly feed on fish, sharks and other marine reptiles.

Scientists have found that these dragons can give birth to live cubs.

Name: Eye Dragon

Pronunciation: Off-THAL-moh-SAW-rus

Meaning: A reptile with big eyes.

Size: 4 meters long.

Weight: 3 tons

Year: Late Jurassic,10.65 billion years to10.50 billion years ago.

Location of discovery: Europe, North America and Argentina

The weight is equivalent to two small family cars.

The vertebrate with the largest eyes ever.

It was first discovered in11920s.

When dinosaurs ruled the land, ichthyosaurs occupied the ocean-about 200 million to 65 million years ago. Bigeyed ichthyosaur is a common ichthyosaur.

These prehistoric marine reptiles are very similar to modern dolphins, although they are not related to each other. Big eyes with a diameter of 22 cm enable it to find its prey in poor light.

Ichthyosaurs can dive to a depth of 500 meters to hunt food-just one breath.
