Datu dibertigarriak
Baotianmansaurus is known from only one partial skeleton, including back bones, ribs, and part of a shoulder blade.1
Its back bones had a spongy texture, which is a special feature that helps scientists tell it apart from other sauropods.1
The fossils were found in the Gaogou Formation, a place where dinosaur eggs are common but body fossils are rare.1
Scientists disagree about exactly where Baotianmansaurus belongs on the sauropod family tree. Some think it is a titanosaur, others think it is a close relative of Euhelopus.1
The name Baotianmansaurus comes from the Baotianman National Nature Reserve in China, where the fossils were discovered.1
One estimate says Baotianmansaurus was about 22.5 meters (74 feet) long and weighed as much as 21 tonnes (46,000 pounds).1
