Diplodocus
Type of dinosaur: Sauropod
Period: Late Jurassic
Where found: North America
Length: Around 25 meters (82 feet
Diplodocus, like all other sauropods, was a giant, four-legged dinosaur with a
long neck and tail. It may have used its long tail as a whip for protection
against predators.
Diplodocus was around 25 metres (82 ft.) in length. It weighed between 10
and 26 metric tonnes (11 and 29 short tons). It lived in North America during
the late Jurassic Period.
Spinosaurus
Type of dinosaur: Theropod, spinosaurid
Period: Early to mid-Cretaceous
Where found: North Africa
Length: Approximately 15-18 meters (49-59 feet), recent estimates
suggest it might have been the largest of all known carnivorous
dinosaurs
Stegosaurus
Type of dinosaur: Armored dinosaur (Thyreophoran)
Period: Late Jurassic
Where found: North America and Europe
Length: Around 9 meters (30 feet)
Troodon
Type of dinosaur: Theropod, dromaeosaurid
Period: Late Cretaceous
Where found: North America
Length: About 2-2.4 meters (6.5-8 feet)
Tyrannosaurus
Tyrannosaurus is one of the largest land-based meat-eaters of all time. Not
only was it strong; it was also intelligent, fast, and equipped with excellent
senses of both sight and smell.
One feature of tyrannosaurus is its huge skull. The skull would have been able
to support large jaw muscles, giving tyrannosaurus a powerful bite.
Utahraptor
As a member of the raptor family, Utahraptor was a carnivorous dinosaur
characterized by a large sickle-shaped claw on each foot. It was much larger
than other raptors like Velociraptor. It likely used its claw to pin down prey
while delivering fatal bites with its sharp teeth.
Velociraptor
Velociraptor was a small, bird-like, predatory dinosaur of the late Cretaceous
Period. Its name–which means ‘swift plunderer’–accurately describes this
speedy, fierce carnivore.
Velociraptor was armed with sharp teeth and sharp claws. Its most fearsome
weapons were the large, curved inner claws on either foot. These were
probably used not only for slashing and ripping, but also to grab and restrain
the velociraptor’s unfortunate prey.
Brachiosaurus
Type of dinosaur: Sauropod
Period: Late Jurassic
Where found: North America, Africa
Length: About 18-26 meters (59-85 feet)
This huge sauropod grew up to 25 metres (82 ft.) in length and weighed
between 30 and 50 metric tonnes (33 and 55 short tons). It was one of the
largest land animals ever. Brachiosaurus’s name means ‘arm lizard’, because of
the way its forelimbs joined its shoulders.
Gallimimus
Type of dinosaur: Ornithomimid
Period: Late Cretaceous (around 70 million years ago)
Where found: Mongolia
Length: Up to 20 feet (6 meters)
Gallimimus, with its long legs and ostrich-like build, was built for speed. It had
large eyes, a long neck, and a toothless beak. As an omnivore, it likely
consumed a diet of plants, insects, and small animals.
Megalosaurus
Type of dinosaur: Theropod
Period: Middle Jurassic
Where found: England
Length: Around 6 meters (20 feet)
Megalosaurus was around 9 metres (30 ft.) in length and weighed around 1
metric tonne (1.1 short tons). It stood on two legs, and was a predator. It lived
in the middle Jurassic Period.
Parasaurolophus
Type of dinosaur: Hadrosaurid (duck-billed dinosaur)
Period: Late Cretaceous
Where found: North America
Length: Around 9.5-10 meters (31-33 feet)
Parasaurolophus was a Late Cretaceous herbivore. It was around 10 metres (33
ft.) in length and weighed around 3.5 metric tonnes (4 short tons).
Parasaurolophus had a distinctive crest at the back of its head. Tubes inside of
this crest were connected to its nostrils.Scientists speculate that this
arrangement may have been used to produce sound.
