Ornithomimosauria ("bird-mimic lizards") are theropod dinosaurs which bore a superficial resemblance to the modern-day ostrich.They were fast, omnivorous or herbivorous dinosaurs from the Cretaceous Period of Laurasia (now Asia, Europe and North America), as well as Africa and possibly Australia. The group first appeared in the Early Cretaceous and persisted until the …

Zhuchengtyrannus was a large carnivorous theropod, and the holotype has been estimated to have been "similar in size and gross morphology to Tarbosaurus", which would result in a body length of 10 m (33 ft) and a body mass of 4.5 t (5.0 short tons) based on the largest Tarbosaurus specimen. The holotype dentary was significantly smaller than the corresponding bones of one …

Meraxes was a very large theropod, weighing approximately 4.26 metric tons (4.70 short tons). Its skull alone is 1.27 m (4.2 ft) long, rivalling that of Acrocanthosaurus which has a skull length of 1.23 m (4.0 ft). The shapes and proportions of various bones (i.e. skull, scapula, metacarpals, ischial shaft, foot, etc.) indicate that Meraxes and Acrocanthosaurus had similar proportions …

Guanlong was a relatively small theropod, reaching 3–3.5 m (9.8–11.5 ft) in length and 125 kg (276 lb) in body mass. Its fossils were found in the Shishugou Formation dating to about 160 million years ago, in the Oxfordian stage of the Late Jurassic period, 92 million years before its well-known relative Tyrannosaurus.This bipedal saurischian theropod shared many traits with …
