The longest and largest ornithopods Top 10

Ornithopoda means “bird feet”, from the Greek ornithos (“bird”) and pous (“feet”).

Ornithopods are a group of ornithischian dinosaurs that started out as small, bipedal running grazers, and grew in size and numbers until they became one of the most successful groups of herbivores in the Cretaceous world, and dominated the North American landscape.

Shantungosaurus, meaning “Shandong Lizard”. It is one of the longest and largest known hadrosaurids; the composite skeleton of a medium-sized individual mounted at the Geological Institute of China in Beijing measures 14.72 meters (48.3 ft) in length, and the type skull is 1.63 meters (5.3 ft) long. The weight of this genus is estimated at up to 16 tonnes (18 short tons). With a composite mounted skeleton 16.6 meters long (54.5 ft) it is currently the largest known ornithischian and, indeed the largest non-sauropod dinosaur.
