Sentences describing the appearance of dinosaurs, what is the description of dinosaurs appearance?

The dinosaur's physical description is:

Dinosaurs had leg bones that were large and strong enough to bear huge bodies. At the same time, they have evolved an ingenious construct that reduces the weight of other bones without attenuating their strength.

The smaller, fast-moving dinosaurs evolved a feature that can also be seen in modern animals: thin-walled long bones. The bone resembles a hollow tube, with a thin outer wall made up of heavy bone, which is much lighter bone marrow.

Fast-moving herbivorous dinosaurs, such as Oak Tree Dragon, had this thin-walled long bone. We can assume that this skeleton is meant to reduce weight and thus gain greater speed when escaping from predators.

Body Characteristics of Dinosaurs:

Judging from the existing skeletons in good condition, the tallest and heaviest dinosaur was the long-necked megalosaurus. Fossils of the long-necked dragon were found in Tanzania between 1907 and 1912.

A skeleton model of a group of similarly sized individuals, which is on display at the Humboldt Museum in Berlin, is 12 meters tall and 12 meters long, and is expected to weigh between 30 and 60 tons of living animals. The longest dinosaur, the 27-meter-long diplodocus, was discovered in Wyoming, USA, in 1907 and is now on display at the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania.

Dinosaurs were the dominant terrestrial vertebrates in the Mesozoic and dominated the world's terrestrial ecosystems for more than 100 million years. Dinosaurs first appeared in the Triassic period hundreds of millions of years ago and died out during the late Cretaceous period, about a million years ago.

The brontosaurus was a behemoth, his body was predatory, the elephant was stacked, six in height, the weight of an elephant, and every time it took a step, it let out a boom, like thunder.
