Think T-Rex, but even cooler (and a little less famous)! Allosaurus was a mega meat-eater, hunting other dinosaurs with its huge, sharp teeth and super-strong claws. Imagine a lightning-fast, muscle-packed predator stalking its prey — that’s Allosaurus!

This fierce hunter roamed the Earth around 150 million years ago during the late Jurassic Period. Its name, Allosaurus, means “different lizard” — and it truly was one-of-a-kind. Most fossils have been found in the Morrison Formation in the western United States.

Allosaurus had a big skull, long tail, and walked on two legs. Its short arms each had three claws perfect for grabbing dinner. On average, it grew 8.5 metres long (about 28 feet!) and weighed 2.3 tons — that’s as heavy as a small car!

This dinosaur was a top predator and wasn’t afraid to take on even tough targets like Stegosaurus. With its sharp, saw-edged teeth and incredible speed, Allosaurus Fragilis was one of the fiercest hunters of the Jurassic world!

Meet Diplodocus — a super long, long-necked dinosaur that’s like a giant version of a lizard! 🦕 Its neck and tail were extra-long, and it walked on all four legs. It wasn’t as tall as Brachiosaurus, but it was still huge, and a true gentle giant of the dinosaur world.

Imagine a massive dinosaur slowly strolling through the forests, munching on leaves all day long 🌿 — that’s Diplodocus! It was a peaceful plant-eater that lived around 150 million years ago in what’s now western North America.

Its name comes from Greek words meaning “double beam”, which refers to the unusual shape of the bones in its tail — isn’t that cool? Its tail alone had around 80 vertebrae, making it super long and flexible.

Diplodocus is a famous dinosaur — you’ll see it in films, documentaries, toys, and museums all over the world. Because scientists have found lots of its fossils, they know a lot about how this dinosaur lived.

It could grow up to 35 metres (115 feet) long and weigh 10–15 tons — as big as a small herd of elephants! 🐘🐘

Some early researchers thought Diplodocus might have swum in water, but scientists now know that its chest would have made it too hard to breathe underwater, so it stayed safely on land.

Diplodocus wasn’t just big — it was super long, leaf-munching, tail-swinging amazing! Imagine seeing one walking by…  😲

Meet the Stegosaurus — a dinosaur that looked like a walking tank! 🦕🛡️ Imagine a big lizard with a row of giant plates running down its back like armour, and at the end of its tail, sharp spikes ready to protect it from predators.

Stegosaurus wasn’t the biggest dinosaur around, but it was definitely tough and cool! It mainly ate plants 🌿 and lived a long, long time ago when dinosaurs ruled the Earth. Its unique look with those plates and spikes makes it one of the most famous dinosaurs ever!

The name “Stegosaurus” comes from Greek words: “stegos” meaning roof and “sauros” meaning lizard — perfect for this roofed-back dinosaur!

Stegosaurus lived during the late Jurassic Period, about 150 million years ago, and fossils have been found in western North America and even Portugal, showing they lived in Europe too.

This dinosaur was big and heavily built — about 9 metres (30ft) long, 4 metres (14ft) tall, and weighing up to 5 tons! But even though its body was huge, its brain was only about the size of a dog’s 🐶.

Stegosaurus wasn’t fast — with its short legs, it could move at around 7 km/h (5 mph). Its 17 plates grew from its skin (not its skeleton!) and the biggest ones were about 60 cm (2ft) tall and wide. And those tail spikes? They could reach up to 90 cm (3ft) long, ready to defend this mighty dinosaur from predators.

With its plated back and spiky tail, the Stegosaurus was truly a prehistoric superhero roaming the ancient world! ⚡

Meet the Tyrannosaurus Rex — the king of the dinosaurs! 👑🦖 Imagine the biggest, scariest dinosaur ever, with huge sharp teeth, a massive head, tiny but powerful arms, and a tail that could balance its whole body. T-Rex was the ultimate dinosaur adventure — fierce, fast, and totally awesome!

Its name comes from Greek and Latin: “Tyrannosaurus” means “tyrant lizard,” and “rex” means king — perfect for this dinosaur ruler!

T-Rex lived in what is now western North America, roaming around during the late Cretaceous Period, about 66 million years ago. It walked on two legs, using its long, heavy tail to balance its giant head.

This dinosaur was huge — up to 13 metres (42 ft) long, 4 metres (13 ft) tall at the hip, and weighing up to 7 tons! Its skull alone could measure 1.5 metres (5 ft), and its teeth were gigantic — the largest carnivorous dinosaur teeth ever found, about 30 cm (1 ft) long! 🦷

T-Rex could grow really fast as a teenager, putting on about 600 kg (1,300 lbs) a year for 4 years. Its tiny arms may have looked useless, but they were super strong with two clawed fingers!

Scientists debate whether T-Rex was a hunter or a scavenger, but one thing’s for sure — its forward-facing eyes gave it awesome depth perception, perfect for spotting prey or dinner from far away. Estimates suggest it could run up to around 40 km/h (25 mph) — fast enough to catch some unlucky dinosaurs! ⚡

With its giant teeth, massive size, and roar-worthy reputation, T-Rex isn’t just scary — it’s legendary, and kids everywhere love imagining this ultimate dinosaur king in action! 😲
