Tuojiangosaurus (Tuo river lizard)
Dong et al. - 1977
Estimated 6 meters long
T. multispinus (type)
China, Sichuan Province - Upper Shaximiao Formation
Late Jurassic, 160 million years ago
Tuojiangosaurus, meaning “Tuo river lizard,” is a genus of armored dinosaur that lived during the Late Jurassic period, around 160 million years ago. Its fossils have been found in what is now Sichuan Province, China.
Tuojiangosaurus was a medium-sized dinosaur, measuring up to 20 feet (6 meters) in length and weighing around 2 tons. It had a heavily armored body, with rows of bony plates running down its back and a spiky tail for defense against predators. Its skull was also heavily armored, with bony knobs and ridges protecting its eyes and nasal passages.
Tuojiangosaurus was a herbivorous dinosaur, using its powerful jaws and teeth to grind up tough plant material. Its teeth were self-sharpening, meaning that as the upper and lower teeth rubbed against each other, they were constantly being worn down and replaced.
One of the most interesting features of Tuojiangosaurus is its forelimbs, which were relatively short and had three-fingered hands with large, sharp claws. These claws may have been used for defense or for grasping onto vegetation.
Tuojiangosaurus is one of the best-known armored dinosaurs from China and has provided valuable insights into the evolution and diversity of this group of dinosaurs. Its fossils have helped scientists to better understand the anatomy and behavior of armored dinosaurs, and ongoing research continues to shed light on their biology and ecology.
In conclusion, Tuojiangosaurus was a heavily armored dinosaur that lived during the Late Jurassic period in what is now China. It was a medium-sized herbivore with a powerful jaw and teeth for grinding up tough plant material. Its forelimbs had large, sharp claws, which may have been used for defense or for grasping onto vegetation. Tuojiangosaurus has provided valuable insights into the evolution and diversity of armored dinosaurs and is a fascinating subject for paleontologists and dinosaur enthusiasts alike.
