Skeletal composite of the chilean titanosaur Atacamatitan chilensis. A fragmented sauropod known from the holotype SGO-PV-961, found in the Atacama Desert. The preserved elements consist of:[1] Right femur, the proximal end of a humerus, two dorsal vertebrae, posterior caudal vertebrae, dorsal ribs and a possibly fragmentary element of the sternum, other fragmented caudal vertebrae and indeterminate bones.[1] Due to the fragmented nature of the holotype, most cladistic analyzes exclude Atacamatitan. Nevertheless, in 2012, Rubilar-Rogers and Gutstein conducted a preliminary cladistic analysis which placed Atacamatitan within the Lithostrotia.[2] The original description lacks a lateral view for the humerus and femur, the lateral view for the humerus was based on Alamosaurus and Opisthocoelicaudia, since it shows resemblance with them. The lateral view of the femur is based on Mendozasaurus for the same reason. Color Key Known Unknown
