The heaviest Ornithischians Top 10

Weight, dimensions, size of Ornithischians (Ornithischia)

The Ornithischia is one of the two clade of dinosaurs beside to the Saurischia.

To better distinguish the dinosaurs from each other, the British paleontologist Harry Govier Seeley (1839-1909) subdivided them in 1887. He divided the reptiles into Saurischia and Ornithischia. The distinction was based on the position of the pelvic bones, which were found in the skeletons of the dinosaurs. The lizard pterosaurs had an arrangement of the pelvic bones similar to that of other reptiles. In contrast, the pelvic dinosaurs show similarities to the birds in their pelvic structure. There is no relationship to them, because the birds developed from a sideline of the Saurischia.

Today we present the world’s largest list of Ornithischians (Ornithischia) ranked by weight. Soon we will present a list of the longest Ornithischians (Ornithischia).
