The longest Stegosaurians (Stegosauria) TOP 10

Length, dimensions, size Stegosaurians (Stegosauria)

The Stegosauria were four-legged, herbivorous dinosaurs, characterized by a double row of bony plates or spines along the back and top of the tail. The best-known representative was Stegosaurus, however, a total of over a dozen genera have been described. Stegosaurs were medium-sized dinosaurs that were 3 to 9 meters long. The forelimbs were short and strong, the hind limbs long and columnar. The toes of all legs ended in broad hooves. For all stegosaurs (with the exception of the original Huayangosaurus ) the hind legs were significantly longer than the front legs, which brought them into a forward bent position and positioned the head close to the ground. These animals could only move slowly. The tail was long and was probably kept horizontally straight.

Stegosauria – temporal range: Middle Jurassic – Early Cretaceous, 169–125 Ma
