酷東西

趣味知識

Dongbeititan is the first named sauropod dinosaur from the Yixian Formation, part of the famous Jehol Group.1 2

Its bones were found in a valley between Libalang and Er Valleys, about 5 km northwest of the Sihetun Fossil Museum.1

The species name dongi honors Chinese paleontologist Dong Zhiming for his work on Chinese dinosaurs.1

Dongbeititan had a camellate internal structure in its presacral vertebrae, meaning the bones were filled with tiny air spaces like a sponge.2

Scientists found a tooth of the predatory dinosaur Sinocalliopteryx embedded in one of Dongbeititan's ribs, showing it was scavenged or attacked.1

It is a basal titanosauriform, more advanced than Euhelopus but less advanced than Gobititan.1 2

發現: Dongbeititan was named in 2007 by Wang Xuri and colleagues based on a partial skeleton found in the Yixian Formation of Liaoning, China. The fossils were collected by the Dalian Natural History Museum.1 2
仍有爭議: Scientists are not sure exactly how big Dongbeititan grew because only a partial skeleton has been found.3 1
