The Abrosaurus name means "delicate lizard". This sauropod was a herbivore from the mid Jurassic Period. The nickname refers to the large openings separated by thin boney struts. The Abrosaurus was discovered in 1984 in Asia. It was first described in 1986 by Ouyang Hui, but there are continuous debates on the dinosaur because is was described under the camarasaurid and many think it shouldn't be part of that family.

The only remains found for this dinosaur is a skull which is in very good shape. Currently its located in Zigong in China dinosaur museum.
