Yunnanosaurus was a large sized, moderately-built, ground-dwelling, quadrupedal herbivore, that could also walk bipedally, and ranged in size from 7 meters (23 feet) long and 2 m (6.5 ft) high to 4 m (13 ft) high in the largest species.
Lisowicia compared to a human. The plant-eating dicynodont Lisowicia bojani is the largest-known of all non-mammalian synapsids, at about 4.5 m (15 ft) long, 2.6 m (8 ft 6 in) tall, and 9,000 kg (20,000 lb) in body mass.
At 40 centimetres (16 in) long, the skull of Lishulong is larger than any other sauropodomorph from the Lufeng Formation. The cervical vertebrae are very large and elongated; the centrum of the first preserved cervical vertebra (the axis) is 16.3 centimetres (6.4 in) long, and the centrum of the last preserved cervical vertebra (the tenth consecutive bone in the series) is 19.9 centimetres (7. ...
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
Yunnanosaurus: 1942 Fengjiahe Formation, Lufeng Formation (Early Jurassic, Sinemurian to Pliensbachian) China: Its teeth were self-sharpening similar to those of sauropods, likely through convergent evolution [151] Yunyangosaurus: 2020 Xintiangou Formation (Middle Jurassic, Aalenian to Callovian) China: Potentially an early megalosauroid ...
The Lufeng Formation (formerly Lower Lufeng Series) is a Lower Jurassic sedimentary rock formation found in Yunnan, China.It has two units: the lower Dull Purplish Beds/Shawan Member are of Hettangian age, and Dark Red Beds/Zhangjia'ao Member are of Sinemurian age. [1]
Classification of dinosaurs. Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria."
