MOST AMAZING DINOSAURS
**Dinosaur Information:**
Tyrannosaurus rex
('Tyrant lizard king')
Carnivore
Cretaceous period, 67-66 MYA
Found in: Western North America
Lived in: Forests with swamps and rivers
**Descriptive Text Boxes:**
* **Long-lived:**
T-rex was able to live for
up to 30 years
* **Clawed grip:**
Although T-rex's arms
were small, each with
two claws, they were
strong, able to grip
prey or push itself off
the floor
* **Balance:**
T-rex's huge head was
balanced by its heavy tail
* **Scales or feathers?**
T-rex may have had feathers
on at least part of its giant
body, just like a bird
* **Fact:**
The largest T-rex skulls
ever to be found are
1.5m across, and
some of the T-rex
teeth were up to
30cm long
**Dino skill:**
Tyrannosaurus rex
T-rex may have had one of the most vicious bites
of any animal to have lived, many times stronger
than lions and sharks and capable of crunching
bone and ripping apart its prey.

DID YOU KNOW? Velociraptors probably hunted as individuals, rather than in a pack
Velociraptor
('Swift plunderer')
Carnivore
Cretaceous period, 75-71 MYA
Found in: China, Mongolia
Lived in: Desert
Image Description:
The central image is a full-body depiction of a Velociraptor, shown in profile. It is rendered with a scaly, reptilian texture, contrary to the "Feathered fiend" text which notes this is an older depiction. It has a long tail, sharp teeth visible in its open mouth, and a distinct large claw on its hind foot. Its eye is a bright yellow. It is standing on its hind legs. Arrows point from descriptive text boxes to specific parts of the dinosaur's body or related images.
Fact box (shaped like a dinosaur footprint):
In the Jurassic Park films Velociraptors were tall and scaly, but in reality they were more like large birds and were much, much smaller
Small size
Velociraptors were small, like a large chicken
(An arrow points from this text box towards the area near the hind leg of the dinosaur).
Warm-blooded
Velociraptors were probably warm-blooded
(An arrow points from this text box towards the neck/shoulder area of the dinosaur).
Feathered fiend
Though long thought to be scaly (as pictured here), it's now believed that velociraptors had feathers that were used for display, covering nests or providing added speed when running
(An arrow points from this text box towards the tail/hindquarters area of the dinosaur).
Dino skill
Velociraptor
Velociraptors were loners, hunting other small dinosaurs by launching surprise attacks and then chasing down their prey.

Dino skill
Allosaurus
Allosaurus was able to sniff out its prey, like Stegosaurus and Diplodocus, with a keen sense of smell.
Killer rating: 4/5
Speed: 4/5
Defence: 4/5
**Annotated Information:**
* Eyesight: Forward-facing eyes helped focus on prey
* Keeping balance: Its large and terrifying skull was balanced by its heavy tail, so that it didn't fall forward all the time
* Jaw strength: Its mighty jaws could clamp down hard on its prey, but not as hard as an alligator, for example
* Claws: Razor-sharp claws
* Shorter stride: Their legs weren't as long as a Tyrannosaur's and they couldn't run as fast
**Fact box:**
Fact
Allosaurus' backward-facing, 10cm-long teeth meant that it could continuously push its prey further down its mouth
**Image Description:**
The image is an informative graphic about the Allosaurus dinosaur. The main element is a large, detailed illustration of an Allosaurus standing on its hind legs, viewed from the side. Its head, neck, and tail are visible. Annotations with lines point from text boxes to relevant parts of the illustration (eyes, neck/head/tail area, jaw, claws, legs/stride).

DID YOU KNOW? Separated by millions of years, T-rex and Spinosaurus would never have met
**Spinosaurus**
('Spine lizard')
Carnivore
Cretaceous period, 112-97 MYA
Found in: North Africa
Lived in: Forests
**Largest carnivore**
Spinosaurus was taller than T-rex
**Fact**
Spinosaurus is the largest meat-eating dinosaur that has ever existed, bigger than a T-rex. Its diet consisted of fish and land animals
**Crocodile-like**
Its head was the longest of any carnivorous dinosaur, the size of a human being, and was shaped like a crocodile's head
**Sail back**
The giant 1.5m spine, sometimes called its 'sail', could have been used to attract mates, control body temperature and warn off competitors
**Grasping arms**
Claws on its small arms could grab prey
**Dino skill**
Spinosaurus
Its teeth were arranged in a 'fish trap' at the front of its mouth to better catch slippery fish, while its nostrils were turned inward, so it could eat and breathe at the same time while in the water.
Killer rating: 4/5

**Did You Know?**
DID YOU KNOW? Carnotaurus was given its name due to the bull-like horns on its head
**Main Subject Information:**
Carnotaurus
('Meat-eating bull')
Carnivore
Late Cretaceous, 70 MYA
Found in: Argentina
Lived in: Lake environments
**Featured Attributes/Facts (Labeled):**
* Searching smell: It used its sense of smell to hunt
* Scaly hide: Carnotaurus' scales were small and pebble-like
* Poor vision: Carnotaurus had small eyes, so its vision was not very good. Combined with not being able to turn easily, it probably just smashed through obstacles
* Strong thighs: Carnotaurus had powerful thigh muscles that were so big they weighed twice as much as a human being. The Carnotaurus as a whole weighed the same as a small car
**Fact Box (Footprint shape):**
Fact
Carnotaurus could run very fast, faster than the T-rex, but it could not turn very well, so it tended to charge prey in straight lines
**Dino Skill Box:**
Dino skill
Carnotaurus
With the horns on its forehead and muscular neck, Carnotaurus could head-butt its prey into submission.

Welcome to the amazing world of dinosaurs! These incredible reptiles dominated Earth for over 160 million years during the Mesozoic Era. From fierce carnivores like Tyrannosaurus rex to gentle giants like Brontosaurus, dinosaurs came in countless shapes and sizes. Some soared through the skies, others ruled the seas, and many roamed the land in spectacular diversity.
Welcome to the amazing world of dinosaurs! These incredible creatures dominated Earth for over 160 million years. From tiny feathered dinosaurs to massive long-necked giants, they came in all shapes and sizes. Today we'll explore some of the most fascinating dinosaurs ever discovered!
Meet the giant predators that ruled the ancient world! Tyrannosaurus rex, the tyrant lizard king, had a bite force of over 12,000 pounds - enough to crush a car! Despite its tiny arms, T-rex was a formidable hunter. Spinosaurus was even larger, reaching over 50 feet long with its distinctive sail back, and spent much of its time hunting fish in rivers. Allosaurus, though smaller, was incredibly agile with razor-sharp claws and excellent eyesight for tracking prey across the prehistoric landscape.
Not all dinosaur predators were giants! Velociraptor was actually about the size of a large chicken, covered in feathers, and hunted alone rather than in packs like in movies. Its most fearsome weapon was a curved claw on each foot. Compsognathus was even smaller but incredibly fast, capable of running at 60 kilometers per hour - that's half the speed of a cheetah! These small predators were perfectly adapted for catching quick prey like insects and small reptiles.
The discovery of feathered dinosaurs revolutionized our understanding of bird evolution! Archaeopteryx, about the size of a pigeon, was the first known bird but still had teeth and claws like its dinosaur ancestors. It could glide short distances between trees. Sinosauropteryx was the first dinosaur whose color was scientifically determined - it had reddish-brown feathers with orange and white stripes on its tail. These feathers weren't for flight but for warmth and display, proving that many dinosaurs were actually warm-blooded!
Dinosaurs dominated Earth for an incredible 160 million years, far longer than humans have existed! They lived through three major periods: the Triassic, Jurassic, and Cretaceous. While most dinosaurs went extinct 66 million years ago when an asteroid hit Earth, they didn't completely disappear. Birds are actually living dinosaurs! Every time you see a bird, you're looking at a modern dinosaur. Through fossils, we continue to discover new species and learn amazing facts about these incredible creatures that once ruled our planet.
Meet the swift hunters of the dinosaur world! Velociraptor was actually about the size of a large turkey, covered in feathers, and hunted alone using stealth and its deadly sickle claw. Deinonychus was a pack hunter with a large brain and flexible neck, allowing it to attack from multiple angles with eagle-like precision. Carnotaurus, the horned meat-eating bull, was built for speed despite its poor eyesight, using its incredible sense of smell to track prey across vast distances. These agile predators proved that in the dinosaur world, speed and intelligence could be just as deadly as size!
The discovery of feathered dinosaurs revolutionized our understanding of prehistoric life! Archaeopteryx, about the size of a pigeon, was the first known bird-dinosaur with teeth, wing claws, and black-tipped feathers for gliding between trees. Even more amazing is Sinosauropteryx - the first dinosaur whose actual colors were scientifically determined! It had reddish-brown fuzzy feathers with bright orange stripes on its tail. These feathers weren't for flight but for warmth and display, proving many dinosaurs were warm-blooded like modern birds. Fossil evidence shows us that the line between dinosaurs and birds is much blurrier than we once thought!
欢迎来到神奇的恐龙世界!恐龙是地球历史上最令人着迷的生物群体,它们统治地球长达1.65亿年,这比人类存在的时间长800倍!从巨大的霸王龙到温和的长颈龙,恐龙的多样性令人惊叹。今天我们将一起探索这些史前巨兽的秘密。
霸王龙,学名暴君蜥蜴王,是最著名的恐龙之一。它们体长可达13米,体重达9吨,拥有地球历史上最强大的咬合力之一,高达12800公斤,相当于一辆卡车的重量!虽然霸王龙的前肢很小,但它们非常强壮,可以举起180公斤的重物。巨大的头部由沉重的尾巴平衡,使它们能够保持稳定。
迅猛龙是真实存在的恐龙,但与侏罗纪公园电影中的形象有很大不同。真实的迅猛龙体型很小,大约只有大型鸡的大小,体长1.5到2米。它们很可能覆盖着羽毛,拥有锋利的镰刀状爪子用于狩猎。迅猛龙智商很高,可能进行群体狩猎,是非常成功的小型掠食者。
恐龙时代跨越了三个主要地质时期。三叠纪是恐龙的起源时期,出现了最早的小型恐龙。侏罗纪见证了巨型蜥脚类恐龙的繁荣,如梁龙和雷龙。白垩纪是恐龙的黄金时代,霸王龙和三角龙等著名恐龙都生活在这个时期。然而,6600万年前一颗小行星撞击地球,导致了恐龙的大灭绝,结束了它们长达1.65亿年的统治。
恐龙的传奇故事跨越了1.65亿年,经历了三个主要时期。虽然大部分恐龙在6600万年前的小行星撞击中灭绝,但它们的遗产依然存在!鸟类实际上就是活着的恐龙——每当你看到麻雀或老鹰时,你其实是在看现代恐龙。科学家们通过DNA分析和化石研究不断发现新物种和惊人事实。恐龙时代从未真正结束——它只是进化出了翅膀,学会了飞翔!
