Sinosauropteryx
"Sinosauropteryx" was a small bipedal theropod, noted for its short arms, large first finger (thumbs), and long tail. The taxon includes some of the smallest known adult non-avian theropod specimens, with the holotype specimen measuring only in length, including the tail. However, this individual was relatively young. The longest known specimen reaches up to in length, with an estimated weight of .
Corythosaurus
Benson "et al." (2012) estimated that "Corythosaurus" has an average length of . Richard Swann Lull's earlier length estimate, published in 1942, found a slightly longer total length of , a size similar to "Lambeosaurus lambei", another Canadian lambeosaurine. In 1962, Edwin H. Colbert used models of specific dinosaurs, including "Corythosaurus", to estimate their weight. The "Corythosaurus" model used, was modelled by Vincent Fusco after a mounted skeleton, and supervised by Barnum Brown. After testing, it was concluded that the average weight of "Corythosaurus" was . More recent size estimates of "Corythosaurus", published in 2001, find the genus to be among the largest hadrosaurids, only smaller than "Shantungosaurus" and "Parasaurolophus". The total length of "Corythosaurus" specimen AMNH 5240 was found to be , with a weight of .
