趣味知識

Bashanosaurus is one of the oldest known stegosaurs and the earliest stegosaur found in Asia.2 1

Its fossils were discovered in 2016 in a dinosaur quarry in Chongqing, China, and scientists named it in 2022.2 1

Bashanosaurus had a mix of features from early armored dinosaurs and more advanced stegosaurs, like a flared shoulder blade and tall stalks on its back vertebrae.2

The name 'primitivus' means 'primitive' because this dinosaur is one of the earliest branching stegosaurs.2 1

Bashanosaurus lived during the Middle Jurassic, about 167 to 164 million years ago, in a semi-arid environment with red mud and siltstone.2 1

Only a partial skeleton of Bashanosaurus has been found, including a back vertebra, tail bones, shoulder bones, leg bones, and armor plates.2

發現: Bashanosaurus was discovered in 2016 in a dinosaur quarry in Laojun Village, China, and named in 2022 by Hui Dai and colleagues. The fossils belong to three individuals, with one partial skeleton chosen as the holotype.2 1
仍有爭議: Scientists are still debating whether stegosaurs first evolved in Asia, because Bashanosaurus and other early stegosaurs are all from China, but the fossil record from other places is very sparse.2
