Skeletal characteristics
Strength was the most important requirement for the massive phytophagous dinosaurs. Their leg bones were large and strong enough to carry a huge body. At the same time, they have evolved an ingenious construction that reduces the weight of other bones without causing a loss of strength.
Those smaller, fast-moving dinosaurs, on the other hand, evolved a feature that can also be seen in modern animals: a thin-walled long bone. This bone is like a hollow tube, with a thin outer wall made up of heavy bone and a much lighter bone marrow in the center of the bone. Fast-moving phytophagous dinosaurs, such as Acornosaurus, had these thin-walled bones. We can hypothesize that this skeleton was used to reduce weight and thus gain greater speed when fleeing from predators.
Physical Characteristics
Dinosaurs as a whole were very large. Using dinosaurs as a standard, the suborder Sauropods were among the giants. During the long age of dinosaurs, even the smallest lizard-footed dinosaurs were larger than any other animal in their habitat, while the largest lizard-footed ones were several orders of magnitude larger than any animal that appeared on the surface.
Most dinosaurs were much smaller than the large lizard-footed dinosaurs. Available evidence suggests that the average size of dinosaurs was constantly changing throughout the Triassic, Early Jurassic, Late Jurassic, and Cretaceous periods. Most theropod dinosaurs weighed between 100 and 1,000 kilograms, while most Holocene predatory carnivores weighed between 10 and 100 kilograms. Estimates of dinosaur weights, for the most part, range between 1 and 10 tons. A study by the National Museum of Natural History in London states that dinosaurs averaged around 100 kilograms, while Cenozoic mammals mostly averaged between 2 and 5 kilograms
The tallest and heaviest dinosaur in terms of available skeletons in good condition is the long-necked Giraffatitan (Giraffatitan brancai, formerly known as Brachiosaurus brachiosaurus). Fossils of Giraffatitan were found in Tanzania between 1907 and 1912. The skeleton model, assembled from a number of similarly sized individuals and now on display at the Humboldt Museum in Berlin, is 12 meters high and 22.5 meters long, and is expected to weigh between 30 and 60 tons in the living body. The longest dinosaur is the 27-meter long Beamosaurus, which was discovered in Wyoming, USA in 1907 and is now on display at the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania.
The major difference between dinosaurs and other reptiles is their stance and mode of travel; dinosaurs had a fully upright stance, with their limbs constructed directly underneath their carapace. This structure was more favorable for walking and running than other types of reptiles, such as crocodiles, whose limbs extended outward. Depending on the structural features of the waist, dinosaurs can be divided into two main groups: Saurischia (lizard-hipped) and Ornithischia (bird-hipped). The difference between the two is mainly in their girdle structure.
Most Saurischia dinosaurs have a pubic bone that protrudes forward, while Ornithischia dinosaurs have each pubic bone angled backward. In addition to differences in hip structure, the two groups of dinosaurs differed in life and behavioral characteristics. The lizard-hipped dinosaurs include herbivorous lizard-footed dinosaurs that walked on all four limbs and carnivorous theropod dinosaurs that walked almost on two limbs.
The girdle of lizard-hipped dinosaurs is triple-shot when viewed from the side, with the pubic bone extending forward below the gut bone and the sit bones extending backward, such that the structure is similar to that of a lizard.
In the girdle of the order Ornithischia, the gut bone is greatly expanded both anteriorly and posteriorly, with a large anterior pubic ramus on the anterior side of the pubic bone extending below the gut bone, and the posterior side is even more greatly extended parallel to the sciatic bone extending anteriorly below the gut bone. The pelvis is therefore quadrangular when viewed from the side
