The first quarry with Giraffatitan material was "Site D", located about one kilometre northeast of the Tendaguru Hill and opened on 21 June 1909. It contained a relatively complete skeleton of a medium-sized individual, lacking the hands, the neck, the back vertebrae and the skull. It included an articulated series of twenty-nine tail vertebrae.
The skull differed from that of Giraffatitan in its U-shaped (instead of W-shaped) suture between frontal and nasal bones, a shape which appears more pronounced by the frontal bones extending forward over the orbits (eye sockets). Similar to Giraffatitan, the neck of the occipital condyle was very long. [30] [34]

Although Abydosaurus lived some 50 million years after Giraffatitan, the skulls of these two genera are similar except for the narrower, sharper teeth and smaller nose of Abydosaurus. Abydosaurus can be differentiated from all other sauropods, including Giraffatitan , by subtle features of the nasal and maxillary bones, its relatively small ...
The replica outside the Field Museum of Natural History in 2013. In 1999, an all-weather cast of Riggs' Brachiosaurus was installed on the museum's northwest terrace.
