|Holotype specimen in 1909|
Abdallahsaurus, meaning "Abdallah's lizard", is a genus of sauropod dinosaur that lived during the late Jurassic Period (Kimmeridgian–Tithonian stages). It was originally named as a possible synonym species of Giraffatitan (G. fraasi). The holotype "Skeleton R" discovered in Tendaguru, Tanzania. The skeleton contains a radial bone, an ulna, a manus, a pubis, an ischium and probably a fibula. It was once thought to be the same as Giraffatitan brancai, but it was separated by Gerhard Maier in 2003.
