Chungkingosaurus (Chungking lizard)
Z. Dong, S. Zhou, and H. Zhang - 1983
Estimated 7-8 meters long
C. jiangbeiensis (type)
China - Sichuan Province - Dashanpu/Upper Shaximiao Formation
Late Jurassic, 160-145 million years ago
Chungkingosaurus is a genus of dinosaurs that lived in the Late Jurassic period, approximately 160 to 145 million years ago. This dinosaur was named after the city of Chongqing, in the Sichuan province of China where the first fossils were discovered in the 1970s.
Chungkingosaurus was a small-to-medium-sized dinosaur, with an estimated length of around 7 to 8 meters. This dinosaur had a long neck and a relatively small head, with a relatively short and wide snout, and a large number of small, sharp teeth. This species was likely a bipedal herbivore, feeding on a variety of plants and vegetation.
One of the most distinctive features of Chungkingosaurus was the presence of a large, bony crest on the top of its head. The exact purpose of this crest is not entirely clear, but it is thought that it may have been used to produce vocalizations or to display to potential mates.
The fossils of Chungkingosaurus are relatively rare, with only a few specimens having been found. However, these fossils have provided valuable information about the anatomy and biology of this dinosaur, and have helped to shed light on the evolutionary relationships between different dinosaur groups.
Overall, Chungkingosaurus is an important dinosaur for understanding the evolution and diversity of dinosaurs in the Late Jurassic period, and is a fascinating example of the incredible variety of dinosaurs that lived in the distant past.
