Physical characteristics of dinosaurs

Dinosaurs are generally very large. By dinosaur standards, sauropods are the giants. During the long age of dinosaurs, even the smallest sauropods were larger than other animals in their habitats, and the largest sauropods were several levels larger than anything that had ever appeared on the surface.

Most dinosaurs were much smaller than the large sauropods. Existing evidence shows that the average size of dinosaurs continued to change 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 the weight of dinosaurs range mostly from 1 to 10 metric tons. A study by the National Museum of Natural History in London pointed out that the average weight of dinosaurs was about 100 kilograms, while the average weight of new generation mammals was between 2 and 5 kilograms.
