The Ornithischian Dinosaurs
- Thyreophora (armored dinosaurs) Scutellosaurus. Scelidosaurus. Stegosauria.
- Marginocephalia, a group including: Ceratopsia (horned dinosaurs) Pachycephalosauria (bone-heads)
- Ornithopoda, a group including: Hadrosauridae (“duckbilled” dinosaurs) Heterodontosaurus, the “different-tooth” dinosaur.

Baryonyx/Eats

How big are the largest ornithopods in the world?
Later ornithopods became larger, but never rivalled the incredible size of the long-necked, long-tailed sauropods that they partially supplanted. The very largest, such as Shantungosaurus, were as heavy as medium-sized sauropods at up to 23 metric tons (25 short tons) but never grew much beyond 15 metres (50 feet).
What is the rank of an Ornithopoda dinosaur?
Ornithopoda is usually given the rank of Suborder, within the order Ornithischia. While ranked taxonomy has largely fallen out of favour among dinosaur paleontologists, some researchers have continued to employ such a classification, though sources have differed on what its rank should be.
What kind of skeleton has 12 ribs and an elongated skull?
The elongated skull and the number of ribs (10 rather than 12) weren’t anything like those of a human being. Others held the opinion it was the skeleton of an aborted fetus or a primate.
Where are the most bizarre skeletons in the world?
Nevertheless, enough unanswered questions remain to make this bizarre skeleton a true enigma. In Uttarakhand (a state in India) at an altitude of 5,000 meters (16,400 ft) in the Himalyas, as many as 600 skeletons are buried in Roopkund Lake (aka Skeleton Lake). The bones date from the ninth century to the 15th century.
