Size is an important aspect of dinosaur paleontology, of interest to both the general public and professional scientists. Dinosaurs show some of the most extreme variations in size of any land animal group, ranging from tiny hummingbirds , which can weigh as little as two grams, to the extinct titanosaurs , such as Argentinosaurus and ...
Paleontologists have conducted a study scrutinizing bite marks left by meat-eating dinosaurs on the bones of sauropods - the familiar plant-eating dinosaurs with long necks, long tails and four ...
Brachiosaurus humerus bone. In 1903, Elmer Samuel Riggs described and named Brachiosaurus. In 1904, he created a new sauropod family, the Brachiosauridae. [9] [1] He published a complete description of the phenotype after examining the humerus, femur, coracoid, and sacrum of the Brachiosaurus holotype that had been prepared at the Field ...

Titanosauria have the largest range of body size of any sauropod clade, and includes both the largest known sauropods and some of the smallest. [25] One of the largest titanosaurs, Patagotitan , had a body mass estimated to be 69 tonnes (76 tons), whereas one of the smallest, Magyarosaurus , had a body mass of approximately 900 kilograms (2,000 ...
