The largest Ornithischians (Ornithischia) TOP 10

Length, dimensions, size of Ornithischians (Ornithischia)

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

This distinction between dinosaurs was a big step towards better understanding of their relationships and was made in 1887 by Harry Govier Seeley from King’s College London . By then some well-preserved dinosaur skeletons had been described , and Seeley noticed that they could be divided into two groups based on their pelvic anatomy . Seeley called these two groups Saurischia and Ornithischia.

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