Measuring 7.5 meters in its length and standing 2.5 meters tall, the Pentaceratops was one of the largest ceratopsid dinosaurs. Unlike the more famous Triceratops, the Pentaceratops had a five-horned skull. All ceratopsids had a powerful frill, which was probably little used to defend themselves. In all likelihood, the Pentaceratops had the largest known skull of all land-living animals. Quite a thick skull.

With seventy centimeters, this two-legged and feathered predator was quite small considering other dinosaurs.

Velociraptors were probably very intelligent predators that hunted in packs. Although they only stood 60 centimeters tall, these carnivores were able to overpower prey animals considerably larger than themselves. These dinosaurs could run up to 65 kilometers per hour and due to their stiff tail they were able to accomplish fast turns. To eat their prey, Velociraptors had eighty sharp and curved-back teeth in their snout, some of them 2.5 centimeters long. The Velociraptor is considered one of the most intelligent and fastest dinosaurs: a cunning hunter.







• Binomial name: Therizinosaurus
• Conservations status: Extinct [ex]

The Therizinosaurus had huge forelimb claws, each up to one meter long. Until today, nobody has found out what it needed weapons like these for.

The most impressive feature of the Therizinosaurus is its striking gigantic claws. Their purpose has not yet been revealed, however it is likely that it used the claws to defend itself. Since only a few skeletal fragments have been found so far, apart from the claws, one can only assume what the dinosaur actually looked like and what its feeding habits were. However, it undoubtedly lived approx. 70 million years ago and must have looked extremely impressive.







• Binomial name: Tyrannosaurus Rex
• Conservations status: Extinct [ex]
• Global Home: North America
• Primary Habitat: Forest

The 13-meter long Tyrannosaurus Rex was a two-legged predator. With its massive skull and its nearly 20-centimeter long teeth, it was an extremely impressive dinosaur of his time.

The Tyrannosaurus Rex looked very menacing though it was hardly able to use its two-clawed forelegs, as it could not even reach its snout with them. Standing nearly seven meters tall and measuring almost thirteen meters in length, the Tyrannosaurus Rex was probably not a good hunter but a scavenger living off the carrion left over by other animals. It had more than fifty teeth, each longer than 15 centimeters, which it did not use to chew his food but to rip it because it swallowed its food in large chunks. To improve its depth perception while foraging, the eyes of a Tyrannosaurus Rex faced forward allowing the field of vision of either eye to overlap.

 

Styracosaurus were stout dinosaurs that were five and a half metres long and had an impressive skull. This skull was equipped with a mighty and spiky neck frill and a nose horn of up to 50 cm in length.

With a weight of 3 tons and a length of up to 5.5 metres, Styracosaurus were medium-sized ceratopsian dinosaurs, to which the Triceratops also belongs to. These dinosaurs had mighty skulls and lived in the Upper Cretaceous, which means roundabout 85 to 65 million years ago. With their giant nose horn measuring 50 centimetres and the spiked neck frill, giving its skull a massive, triangular appearance, Styracosaurus looked very robust. The function of the neck frill is still subject to speculation. It is assumed that it might have been too thin to work as a protective shield, so it might have served as a communication tool, for example as far as menacing gestures or imposing behaviour is concerned.

The thirteen metre long Tyrannosaurus Rex was a two legged predatory dinosaur. With its powerful head and nearly 20 centimetre long teeth, this dinosaur was an extremely impressive contemporary.

Although the Tyrannosaurus Rex looked quite threatening, it could hardly use its front legs armed with just two claws since they did not even reach his mouth. Nearly seven metres tall and thirteen metres long, the Tyrannosaurus Rex was probably not a very skilled hunter, but rather a scavenger which probably fed on the leavings of other animals. It had more than fifty teeth measuring more than 15 centimetres in length which it used not for chewing but rather for tearing, since it swallowed its food in large chunks. To improve depth-perception when searching for food, the eyes of the Tyrannosaurus Rex were oriented toward the front such that the fields of vision of both eyes overlapped.







• Binomial name: Spinosaurus
• Conservations status: Extinct [ex]
• Global Home: Africa
• Primary Habitat: Desert

This deadly carnivore weighed several tonnes and could grow to be up to 17 metres long! The Spinosaurus had multiple sharp, straight teeth in its crocodile-like mouth. Its meals mainly consisted of other dinosaurs or fish. The intelligently designed sail on its back served several functions. In cold-blooded dinosaurs, the sail probably contributed to vital temperature regulation by collecting or distributing heat. It also served to impress potential mates.

Like a giraffe, this dinosaur grazed on treetops. With chisel-like teeth and a very sharp sense of smell, this plant-eater always found enough to eat. Unlike most another dinosaurs, the Giganotosaurus' front legs were longer than its hind legs which made it easier for this herbivore to reach its food. The Giganotosaurus was one of the largest dinosaurs to ever live; it could reach 17 metres in height and weigh nearly ninety tonnes.

Like a giraffe, this dinosaur grazed on treetops. With chisel-like teeth and a very sharp sense of smell, this plant-eater always found enough to eat. Unlike most another dinosaurs, the Brachiosaurus' front legs were longer than its hind legs which made it easier for this herbivore to reach its food. The brachiosaurus was one of the largest dinosaurs to ever live; it could reach 17 metres in height and weigh nearly ninety tonnes.

This herbivore armed with pencil-like teeth spent most of its time grazing and swallowing its food without chewing. Despite its small head and even smaller brain, this was one of the largest land animals ever existing. With a length of 25 metres and hip height of more than three metres, this dinosaur weighed almost forty tonnes. Its tail alone could reach a length of 17 metres! In terms of age, it wasn't rare for an Apatosaurus to live to be a hundred.
