Dinosaur size
Encyclopedia
Size has been one of the most interesting aspects of dinosaur
science to the general public. This article lists the largest
and smallest dinosaurs from various groups, sorted in order of weight and length.
This list excludes unpublished size estimates (such as those for Bruhathkayosaurus
, possibly the largest dinosaur of all). In some cases, dinosaurs are known that will be included on this list if/when they are officially described. In addition, weight estimates for dinosaurs are much more variable than length estimates, because estimating length for extinct animals is much more easily done from a skeleton than estimating weight.

Sauropods
Sauropod size is difficult to estimate given their usually fragmentary state of preservation. Sauropods are often preserved without their tails, so the margin of error in overall length estimates is high. Mass is calculated using the cube of the length, so for species in which the length is particularly uncertain, the weight is even more so. Estimates that are particularly uncertain (due to very fragmentary or lost material) are preceded by a question mark. Each number represents the highest estimate of a given research paper.Note that, generally, the giant sauropods can be divided into two categories: the shorter but stockier and more massive forms (mainly titanosaur
