' It's called the Giganotosaurus – but for short, it's known as the 'Giga'. This one isn't a genetic hybrid like the Indominus and the Indoraptor – it's a scientifically-documented giant of the Late Cretaceous period. But like its scaly brethren, it's none too pleased to find itself roaming around in the modern day.

Stegosaurus lived about 145 million years ago during the Jurassic period in what's now Colorado, Utah, and Wyoming. It was about the length of a bus and weighed almost 14,000 pounds. But this enormous animal had a brain that was only slightly larger than a walnut.

10 Things you need to know about stegosaurus!

• Stegosaurus is the official state dinosaur for Colorado.
• Stegosaurus lived around 150 million years ago.
• Stegosaurus remains were first discovered during the Bone Wars.
• Stegosaurus' plates are a bit of a mystery!
• Stegosaurus was around 4.3 metres tall and 9 metres long!

Look out get a snare on that.

However, the T-rex wasn't dead and it rose to join the fight against the Gigantosaurus. But it was really the Therizinosaurus, with T-rex's help, that brought down Gigantosaurus with its deadly claws. The Gigantosaurus was killed by the Therizinosaurus, which stabbed the Giga through the neck.

The Tallest Dinosaur The tallest dinosaurs were the Brachiosaurid group of sauropods. Their front legs were longer than the rear legs giving them a giraffe-like stance. This combined with their extremely long necks, which were held vertically, meant they could browse off the tallest trees.

Many individuals have been found together in fossils, so it's believed that they traveled in herds. There would have been young and old dinosaurs traveling and grazing together. Stegosaurus would have lived close to places where they could find plenty of vegetation - likely in the undergrowth of subtropical forests.

“Far from being feeble, as usually thought, Stegosaurus actually had a bite force within the range of living herbivorous mammals, such as sheep and cows. Our key finding really surprised us, we expected that many of these dinosaur herbivores would have skulls that worked in broadly similar ways.

They were large, heavily built, herbivorous quadrupeds with rounded backs, short fore limbs, long hind limbs, and tails held high in the air. Due to their distinctive combination of broad, upright plates and tail tipped with spikes, Stegosaurus is one of the most recognizable kinds of dinosaurs.

CycadsMoss Stegosaurus/Eats Stegosaurus ate gastroliths. Small stones that ground its favourite vegetables up in its stomach. It is believed to have eaten plants such as mosses, ferns, horsetails, cycads and conifers or fruits.

A tracking system, also known as a locating system, is used for the observing of persons or objects on the move and supplying a timely ordered sequence of location data for further processing.

The Dinosaur Game (also known as the Chrome Dino) is a browser game developed by Google and built into the Google Chrome web browser. The player guides a pixelated Tyrannosaurus rex across a side-scrolling landscape, avoiding obstacles to achieve a higher score.

The spinosaurus, a dinosaur heavier, bigger and stronger than the T Rex. When compared to the Tyrannosaurus species, the Spinosaurus stood a few meters taller and weighed considerably more.

Both Gianotosaurus and Tyrannosauru Rex were apex predators. In a fight between Giganotosaurus and T-Rex, the Tyrannosaurus would win. The two dinosaurs are pretty similar to one another, but their approaches to fighting would make a world of difference.

The results of this study, which were based on estimated real global biodiversity, showed that between 628 and 1,078 non-avian dinosaur species were alive at the end of the Cretaceous and underwent sudden extinction after the Cretaceous–Paleogene extinction event.

Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth's climate that happened over millions of years.
