All About Dinosaur Information

Basic Dinosaur Facts

  • Dinosaurs are part of the reptile family and have lived on Earth for 245 million years.
  • In 1842 1842 1842, English naturalist Richard Owen coined the term Dinosauria which was derived from Greek dinos, which translates to “fearfully great,” and sauros, which means “lizard. “
  • Dinosaur fossils have been discovered across every continent.
  • All dinosaurs, not avians, died out around 66 million years ago.
  • There are around 700 species of dinosaurs that have died out.
  • Contemporary birds are one of the dinosaurs because they have the same ancestor as the non-avian dinosaurs.


Paleontologists are scientists who investigate the evidence that indicates that animals that died left footprints. The clues to the history of the dinosaurs can be found in fossils, the oldest fossils of an organism, such as teeth, bones, shells, or evidence of activity by animals like footprints and tracks.

Most of what we know about non-avian dinosaurs was based on fossils that include bone teeth and footprints, eggs, and skin prints. For centuries, humans from all over the world have discovered excellent fossilized footprints and bones. The first discoveries resulted in legends and fairy tales believing that these bones belonged to giants or even giants.

Many believe Barnum Brown, who first began work for the American Museum of Natural History in 1897, was one of the most prominent dinosaur hunters of the 18th through the early twentieth century. Barnum Brown began with the American Museum of Natural History in 1897. The Museum has some of his most important discoveries, including the first fossils from Tyrannosaurus Rex ever discovered, and are on display in the Museum’s dinosaur galleries.

Today, in addition to the capacity to remain patient and focused in their observation, paleontologists employ modern technologies to address unanswered questions about dinosaurs and different fossils. The latest imaging techniques, such as CT scans, allow paleontologists to generally see the fossil’s 3D structure without taking away the matrix.

Paleontologists study biomechanics. They employ the principles of engineering and physics to comprehend the movement that non-avian dinosaurs experience. The data taken from fossil bones and observation of motion and muscles in living animals can help scientists discover how non-avian dinosaurs might have moved.

The Age of Dinosaurs

The first dinosaurs that were known were discovered during the Triassic Period (approximately 250 to 200 million years ago). Dinosaurs transformed into wildly diverse animal species with a wide range of physical characteristics that included the birds we see in the present.

Contrary to what most people believe, there aren’t any dinosaurs who lived during the same period. Stegosaurus, for instance, was alive in the Late Jurassic Period, about 150 million years ago, and Tyrannosaurus Rex lived in the Late Cretaceous Period, about 72 million years ago. Stegosaurus had been extinct for around 6 million years before the moment when Tyrannosaurus could walk on Earth.

In the Mesozoic Era (a period of more than 180 million years that comprised three periods: Triassic, Jurassic, and Cretaceous period), An non-avian dinosaur changed into an Avian dinosaur. The avian dinosaur was the first bird and the ancestor of every bird species. All non-avian dinosaurs became extinct after the 66 millennia.

There are a variety of theories regarding the reason behind the massive extinctions of other dinosaurs and other species toward the end of the Cretaceous Period. There is a strong likelihood that a giant asteroid or comet struck Earth during this time, which led to a dramatic shift in the planet’s temperature. Scientists have believed that this event caused devastating consequences for the living things on Earth. However, other causes like the changes in sea level and the massive volcanic activity may be a significant causes of the mass extinctions.

Dinosaur Fossils and Fossilization

  • Paleontologists search for fossils in the ancient rock to determine how species that were extinct for many years were capable of governing themselves.
  • Most fossilized bone fragments are rocks made of minerals and contain none of the material from the bone.
  • Discovering nests and eggs from dinosaurs revealed the habits of some dinosaurs.
  • By comparing the skulls of Protoceratops from different periods (like in the image above), paleontologists can draw observations about how the evolution of dinosaurs took place.
  • To discover what living organisms did in the dinosaur age, Researchers look for clues preserved in ancient rocks, like tooth fossils and fossilized bones, egg footprints, teeth, leaves with teeth, and even the dung of old organisms.
  • Jaws fossilized from the past teeth, dung, and teeth provide significant clues about the kind of dinosaurs that weren’t bird-eaters.
  • Footprints that have been fossilized from several tracks are an intriguing clue about dinosaurs’ behavior and movement.
  • It was believed that feathers could only be found in birds. Recent research, however, has revealed proof of feathered dinosaurs that are not birds.
