My name is famouschobots and here is what I have found out about dinosaurs!
Utahraptor:
Like other raptors, Utahraptor had a big ol’ claw coming out of its foot that it used to slice open its prey. The largest claws could reach up to 9.4 in (23.9 cm)! Not only was it long, it was thick too. While one Utahraptor was insanely dangerous on its own, a small group of them could take down any dinosaur that ever existed.

Megalosaurus:
Robert Plot, an English museum curator, found a bone in 1676 that he believed to be the thigh bone of an ancient giant human being. Based on drawings we have of his find, most assume it was part of a Megalosaurus bone.

Mauisaurus:
Like Liopleurodon, Mauisaurus was a plesiosaur. Mauisaurus measured out to be a whopping 65ft (20m) in length and was the longest sea reptile of them all. Found only in New Zealand fossil beds, Mauisaurus must have been a fearsome predator during its day. They’ve even found a fossil of one fighting a mosasaur!

Argentinosaurus:
If you’re looking for the dinosaur that weighed the most it would have to be Argentinosaurus. This big guy lived about 100 million years ago and weighed 100 tons! In case you don’t realize how big that is, its about the weigh of 20 huge elephants!

dromaeosaurs:
The first dromaeosaurs appeared during the Middle Jurassic. These early raptors were smaller and most of them were covered in feathers. Although they first started appearing during this time, it wasn’t until the Middle and Late Cretaceous that they became more common and diversified. It was during those times that Velociraptor and Utahraptor were roaming the land and eating anything they could get their claws on.

That's all i got it was hard work finding all that information !But at the same time i enjoyed it!
hope i win XD!

Dinosaurs (Greek: δεινόσαυρος, deinosauros) were the dominant terrestrial vertebrate animals for over 160 million years, from the late Triassic period, about 230 million years ago (Ma), until the end of the Cretaceous period, about 65 Ma, when most of them became extinct in the Cretaceous–Tertiary extinction event. The fossil record indicates that birds evolved from theropod dinosaurs during the Jurassic period, and most paleontologists regard them as the only clade of dinosaurs to have survived until the present day.[1]

Dinosaurs were an extremely varied group of animals. Paleontologists have identified over 500 distinct genera[2] and more than 1,000 different species of dinosaur,[3] and remains have been found on every continent on Earth.[4] Some dinosaurs were herbivorous, others carnivorous. Some were bipedal, others quadrupedal, and others were able to shift between these body postures. Many species developed elaborate skeletal modifications such as bony armor, horns or crests. Although generally known for their large size, many dinosaurs were human-sized or even smaller. Most major groups of dinosaurs are known to have built nests and laid eggs, suggesting an oviparity similar to that of modern birds.

The term "dinosaur" was coined in 1842 by Sir Richard Owen and derives from Greek δεινός (deinos) "terrible, powerful, wondrous" + σαῦρος (sauros) "lizard". Through the first half of the 20th century, most of the scientific community believed dinosaurs to have been sluggish, unintelligent cold-blooded animals. Most research conducted since the 1970s, however, has supported what has since become the scientific consensus view: that dinosaurs were active animals with elevated metabolisms and numerous adaptations for social interaction.

Since the first dinosaur fossils were recognized in the early nineteenth century, mounted dinosaur skeletons have become major attractions at museums around the world. Dinosaurs have become a part of world culture and remain consistently popular. They have been featured in best-selling books and films such as Jurassic Park, and new discoveries are regularly covered by the media. As a result, the word "dinosaur" has entered the common vernacular, although its use and meaning in colloquial speech may be inconsistent with modern science. In English, for example, "dinosaur" is commonly used to describe anything that is impractically large,

The taxon Dinosauria was formally named in 1842 by English palaeontologist Richard Owen, who used it to refer to the "distinct tribe or sub-order of Saurian Reptiles" that were then being recognized in England and around the world.[6] The term is derived from the Greek words δεινός (deinos meaning "terrible", "powerful", or "wondrous") and σαύρα (saura meaning "lizard" or "reptile").[7] Though the taxonomic name has often been interpreted as a reference to dinosaurs' teeth, claws, and other fearsome characteristics, Owen intended it merely to evoke their size and majesty.[8] In colloquial English "dinosaur" is sometimes used to describe an obsolete or unsuccessful thing or person,[9] despite the dinosaurs' 160 million year reign and the global abundance and diversity of their avian descendants: modern-day birds.



dinosaurs are now known to have formed a single group.[18][29]



Dinosaurs diverged from their archosaur ancestors approximately 230 million years ago during the Middle to Late Triassic period, roughly 20 million years after the Permian-Triassic extinction event wiped out an estimated 95% of all life on Earth.[30][31] Radiometric dating of the rock formation that contained fossils from the early dinosaur genus Eoraptor establishes its presence in the fossil record at this time. Paleontologists believe Eoraptor resembles the common ancestor of all dinosaurs;[32] if this is true, its traits suggest that the first dinosaurs were small, bipedal predators.[33] The discovery of primitive, dinosaur-like ornithodirans such as Marasuchus and Lagerpeton in Argentinian Middle Triassic strata supports this view; analysis of recovered fossils suggests that these animals were indeed small, bipedal predators.

When dinosaurs appeared, terrestrial habitats were occupied by various types of basal archosaurs and therapsids, such as aetosaurs, cynodonts, dicynodonts, ornithosuchids, rauisuchias, and rhynchosaurs. Most of these other animals became extinct in the Triassic, in one of two events. First, at about the boundary between the Carnian and Norian faunal stages (about 215 million years ago), dicynodonts and a variety of basal archosauromorphs, including the prolacertiforms and rhynchosaurs, became extinct. This was followed by the Triassic-Jurassic extinction event (about 200 million years ago), that saw the end of most of the other groups of early archosaurs, like aetosaurs, ornithosuchids, phytosaurs, and rauisuchians. These losses left behind a land fauna of crocodylomorphs, dinosaurs, mammals, pterosaurians, and turtles.[18]

The first few lines of primitive dinosaurs diversified through the Carnian and Norian stages of the Triassic, most likely by occupying the niches of groups that became extinct. Traditionally, dinosaurs were thought to have replaced the variety of other Triassic land animals by proving superior through a long period of competition. This now appears unlikely, for several reasons. Dinosaurs do not show a pattern of steadily increasing in diversity and numbers, as would be predicted if they were competitively replacing other groups; instead, they were very rare through the Carnian, making up only 1–2% of individuals present in faunas. In the Norian, however, after the extinction of several other groups, they became significant components of faunas, representing 50–90% of individuals. Also, what had been viewed as a key adaptation of dinosaurs, their erect stance, is now known to have been present in several contemporaneous groups that were not as successful (aetosaurs, ornithosuchids, rauisuchians, and some groups of crocodylomorphs). Finally, the Late Triassic itself was a time of great upheaval in life, with shifts in plant life, marine life, and climate.[18] Crurotarsans, today represented only by crocodilians but in the Late Triassic also encompassing such now-extinct groups as aetosaurs, phytosaurs, ornithosuchians, and rauisuchians, were actually more diverse in the Late Triassic than dinosaurs, indicating that the survival of dinosaurs had more to do with luck than superiority.[34]

Types of Dinosaurs[b]





There were many different kinds of dinosaurs.
The smallest types were about the same size as a chicken, and the largest were over 100 feet (30 meters) long.


Different dinosaurs ate different diets. Some types of dinosaurs ate only meat ("carnivores"), some ate only plants ("herbivores"), and some ate both plants and meats ("omnivores").


Just like modern animals, the different types of dinosaurs were related. Biologists use the terms "order", "family", "genus" and "species" to classify dinosaurs and to indicate how closely different types of animals are related.

A dinosaur which is the same species as another dinosaur is of the exact same type, whereas two dinosaurs which are of the same genus are closely related but of different types, and two dinosaurs of the same family are a bit more distantly related and so on.
The chart below shows some of the different types of dinosaurs (divided into herbivores, carnivores and omnivores). In most cases, the chart shows a genus or family of dinosaur, although in some cases a single species may be indicated.
