The earliest known dinosaur appeared about 245 million years ago during the Late Triassic Period (250 to 210 million years ago). Dinosaurs evolved into a very diverse group of animals with a vast array of physical features, including modern birds.Dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea.

Dinosaurs, like Winnie the Pooh, have traditionally been depicted as having very small brains, and therefore not being very intelligent creatures.It is true that, in general, dinosaurs' brains were much smaller than the brains of mammals possessing heads of comparable size. Whereas in a human skull, most of what is under the immediate bone surface is brain matter, a dinosaur skull's key facet is its jaw structure; much of the available space was occupied by powerful biting muscles, with the brain being buried under a thick casing to keep it well protected.

Scientific classification of dinosaur :  

Kingdom:Animalia

Phylum:Chordata

Clade:Dracohors

Clade:Dinosauria

A rough system of estimating dinosaurs' (and other creatures') intelligence is known as the Encephalisation Quotient, or EQ. Developed by the American palaeoneurologist Harry Jerison in the 1970s, a dinosaur's EQ is the ratio of its brain weight relative to the brain weight of a "typical" animal of similar body weight. Typically, warm-blooded mammals and birds have much higher EQ ratings than cold-blooded reptiles of the same size, and there is a wide variation in the estimated EQ ratios of different dinosaur types, which reflects their differing lifestyles and (possibly) metabolic rates.

Some dinosaurs ate lizards, turtles, eggs, or early mammals. Some hunted other dinosaurs or scavenged dead animals. Most, however, ate plants (but not grass, which hadn't evolved yet)

Most dinosaurs have an EQ similar to those of modern reptiles. Typically, herbivores such as the large sauropods, armoured ankylosaurs and stegosaurs are at the lowest end of the scale. It is often said that Stegosaurus had a brain the size of a walnut - in fact it was more like the size of a lime, or a dog's brain, but still relatively small for a dinosaur that grew up to nine metres long. Later ornithischian herbivores of the Cretaceous period, such as Edmontosaurus, possessed slightly bigger brains, but still smaller relative to carnivorous dinosaurs.

Predatory theropods are thought to have relatively larger brains (and excellent eyesight), evolved because of their need to hunt prey at speed. T. rex, for example, had a particularly large brain even compared to other dinosaurian predators its size.However, at the top of the scale (by a distance) are those theropod dinosaurs most closely related to modern-day birds - small- and medium-sized carnivorous dromaeosaurids such as Velociraptor, and troodontids such as Troodon.Troodontids' brains were comparable in size to those of today's flightless birds, and they had large eyes that pointed forward to give them binocular (three-dimensional) vision, and also an acute sense of hearing to help locate their prey.

approximately 66 million years ago

The Cretaceous–Paleogene extinction event, which occurred approximately 66 million years ago at the end of the Cretaceous, caused the extinction of all dinosaur groups except for the neornithine birds.

People also ask : 

What was the first dinosaur?

Ans : The earliest dinosaurs for which we do have well-documented fossils are found in Late Triassic Ischigualasto Formation in northern Argentina. Skeletons discovered in these rock layers include the meat-eating dinosaurs Herrerasaurus and Eoraptor, as well as the plant-eating dinosaur Pisanosaurus.

What is the tallest dinosaur?

Ans : Sauroposeidon was massive and probably grew to 18.5 metres tall making it the tallest dinosaur.

What was the smartest dinosaur?

Ans : Troodon had a large brain for its relatively small size and was probably among the smartest dinosaurs. Its brain is proportionally larger than those found in living reptiles, so the animal may have been as intelligent as modern birds, which are more similar in brain size.

How old did dinosaurs get?

Ans : Early estimates of 300-year lifespans for the largest sauropods were based on comparisons with crocodiles and turtles, which have much slower metabolisms. The consensus is now that Apatosaurus and Diplodocus dinosaurs probably only lived for 70 or 80 years, which is about the same as an elephant today.
