The dinosaur of the day: Chungkingosaurus
- Stegosaur that lived within the Late Jurassic in what’s now China (Higher Shaximiao Formation)
- Herbivore
- Holotype is likely one of the smallest grownup stegosaurs (about 13 ft, 4 m lengthy)
- Different specimens discovered have been longer (estimated to be 16.4 ft, 5 m lengthy)
- Most likely seemed just like Tuojiangosaurus (present in the identical formation), although smaller, with a excessive, slim cranium

- Gregory Paul advised in 2010 that the third specimen was a juvenile of Tuojiangosaurus
- A part of Huayangosauridae, a bunch of basal stegosaurs
- Might have been prey for theropods comparable to Yangchuanosaurus
- Different dinosaurs that lived in the identical time and place included Tuojiangosaurus, and sauropods like Mamenchisaurus
Enjoyable Truth:
