Most of the information known about Stegosaurus comes from the remains of mature animals; more recently, though, juvenile remains of Stegosaurus have been found. One subadult specimen, discovered in 1994 in Wyoming, is 4.6 m (15.1 ft) long and 2 m (6.6 ft) high, and is estimated to have weighed 1.5-2.2 metric tons (1.6-2.4 short tons) [ 36 ...
Skeletal mount of Stegosaurus.. This timeline of stegosaur research is a chronological listing of events in the history of paleontology focused on the stegosaurs, the iconic plate-backed, spike-tailed herbivorous eurypod dinosaurs that predominated during the Jurassic period.

The most derived species, like Stegosaurus, Hesperosaurus and Wuerhosaurus, have very large and flat back plates. Stegosaurid plates have a thick base and central portion, but are transversely thin elsewhere. The plates become remarkably large and thin in Stegosaurus. They are found in varying sizes along the dorsum, with the central region of ...
The massive specimen, named Apex, will be on display at the American Museum of Natural History for four years, the museum said.

Skull of the mount. In 1974, during construction of the Wujiaba dam in Zigong, Sichuan, the remains of a stegosaurian were found.. The type and only species of Tuojiangosaurus, Tuojiangosaurus multispinus, was named and described in 1977 (exactly a hundred years after the naming of Stegosaurus by Othniel Charles Marsh) by Dong Zhiming, Zhou Shiwu, Li Xuanmin and Chang Yijong.
Galton and Carpenter considered Alcovasaurus a member of the Stegosauridae, not more closely related to Kentrosaurus than to Stegosaurus. [1] However, a 2017 phylogeny of stegosaurids by Thomas Raven and Susannah Maidment found that Alcovasaurus lacked the fusion between the trochanters of the femur seen in adult eurypodans (stegosaurians and ankylosaurians), which means that it cannot be ...
