Dinosuar – Top Interesting facts About Ancient Reptiles

Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research, Dinosaurs can therefore be divided into avian dinosaurs, or birds; and non-avian dinosaurs, which are all dinosaurs other than birds

1. The term “dinosaur”

The term “dinosaur” wasn’t coined until 1842, English paleontologist Sir Richard Owen is renowned as the person who coined the term dinosaur, but he had numerous scientific accomplishments, particularly in the area of vertebrate anatomy and paleontology. “Dinosaur” translates to “Terrible reptile.”

2. Non-bird dinosaurs

Non-bird dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous.During the Mesozoic, or “Middle Life” Era, life diversified rapidly and giant reptiles, dinosaurs and other monstrous beasts roamed the Earth.

  1. The extraordinary length of the dinosaurs

The extraordinary length of the dinosaurs’ reign can be difficult to comprehend. In fact, the gap between when Stegosaurus lived and when T. rex lived is greater than the gap between the latter and the present. You’re closer to T. rex on the Earth’s timeline than Stegosaurus is.

The Tyrannosaurus had a life span of around 30 years.Tyrannosaurus is from the Greek word meaning Tyrant Lizard.The dinosaur has many similar features to birds. …Its arms were too short to reach its mouth.It lived in North America in river valleys and forests

The chicken is the closest known modern relative to the T. rex.Chickens and ostriches are only distantly related to each other, so the research says little about what kind of birds might be the closest relatives of the famous carnivore.The dinosaur-ness of birds has been suspected for many years based on anatomical similarities.

  1. carnivorous dinosaur

The largest known carnivorous dinosaur is the Spinosaurus, which could grow to be over 50 feet long and weighed in at over 20 tonnes — three times the weight of a T. rex.Spinosaurus, a genus of theropod dinosaurs belonging to the family Spinosauridae, known from incomplete North African fossils that date to Cenomanian times (roughly 100 to 94 million years ago). Spinosaurus, or “spined reptile,” was named for its “sail-back” feature, created by tall vertebral spines.

  1. Herbivorous dinosaur

On the other hand, the largest known herbivorous dinosaur, and the largest dinosaur overall, is the Argentinosaurus, which could grow to be 115 feet in length and weigh 100 tons (which is more than over a dozen elephants).Given its enormous size, it would be surprising if Argentinosaurus could move much faster than a slowly taxiing 747 jet airplane.

Given its gigantic size, it’s appropriate that Argentinosaurus is classified as a titanosaur, the family of lightly-armored sauropods which spread to every continent on Earth later in the Cretaceous period.

7. Sauropods

It’s speculated that the Sauropods (long-necked dinosaurs like the Argentinosaurus) had stomachs that acted as fermentation chambers. As gas-producing bacteria would be needed to help process their fibrous diets, this would cause these creatures, the largest of all dinosaurs, to fart constantly.

  1. Anchiornis dinosaurs

Among the tinier dinosaurs was Anchiornis, which was no bigger than a pigeon.Anchiornis is a genus of small, four-winged paravian dinosaur. The genus Anchiornis contains only the type species Anchiornis huxleyi, named for its similarity to modern birds. Anchiornis fossils have been only found in Liaoning, China, in rocks dated to the late Jurassic period, about 160 million years ago

9. pterosaurs

While dinosaurs walked the Earth, pterosaurs inhabited the air and plesiosaurs inhabited the water. This means that the well-known flying Pterodactyl (above) and swimming Liopleurodon aren’t technically considered dinosaurs.Pterodactyls lived at the same time as the dinosaurs—but somehow, they’re not actually dinosaurs.

They were flying creatures, and paleontologists keep telling us that dinosaurs are birds. But still, we’re supposed to call pterodactyls “pterosaurs.

  1. Two Type Of Dinosaurs

Dinosaurs are divided into two groups, the lizard-hipped saurischian (A) and the bird-hipped ornithischian (B). Ironically enough, birds evolved from lizard-hipped dinosaurs

11. Ankylosaurus

Ankylosaurus is a genus of armored dinosaur. The Ankylosaurus’ club tail was fortified enough to smash through a T. Rex’s ankles.The top of the dinosaur was almost completely covered with thick armor consisting of massive knobs and oval plates of bone, known as osteoderms or scutes, which are also common on crocodiles, armadillos and some lizards. “They are bones that form within the skin, just like crocodiles,”

  1. Cryolophosaurus

Many dinosaurs, like the massive predator know as Cryolophosaurus (above), were so equipped for the cold that they were able to live in Antarctica.Cryolophosaurus, the “cold-crest lizard,” is notable for being the first meat-eating dinosaur . The most distinctive feature of Cryolophosaurus was the single crest atop its head, which didn’t run front-to-back (as on Dilophosaurus and other crested dinosaurs) but side-to-side.

14. Dinosaurs Eggs

Dinosaurs were egg-laying animals who lived millions of years ago. Scientists study fossilized dinosaur eggs, embryos, and hatchlings to learn more about dinosaurs. Dinosaur eggs are very rare finds, even though dinosaurs laid many eggs. Many dinosaur eggs could grow to be as large as basketballs

15. The last dinosaurs

The last dinosaurs died approximately 65 million years ago. Although the cause of their extinction is still a mystery, climatic change, diseases, changing plant communities, and geologic events could all have played a role.A big meteorite crashed into Earth, changing the climatic conditions so dramatically that dinosaurs could not survive.Ash and gas spewing from volcanoes suffocated many of the dinosaurs.

Diseases wiped out entire populations of dinosaursFood chain imbalances lead to the starvation of the dinosaurs.These all may be the reasons why the dinosaurs became extinct.
