Skeletal restoration ‘’Brachiosaurus’’
FMNH P 25107 (Holotype): This is the most complete adult Brachiosaurus specimen known. Dorsal vertebrae 6-12 are preserved, in addition to a sacrum, two caudals, a rib, a coracoid, a humerus, and a femur. Shown in white.
USNM 21903 ("Potter Creek Humerus"): This single, large humerus has never illustrated in lateral view in detail. Shown in green.
BYU 9754 ("Potter Creek Material"): This specimen includes the rest of the Potter Creek Material, which was excavated years after the humerus. This consists of a radius, two metacarpals, a rib, a dorsal vertebra, and a partial caudal vertebra. Shown in yellow.
USNM 5730 ("Felch Quarry Skull"): This is the skull that Marsh used for his Brontosaurus restoration. It is partially complete and crushed. A 99 cm cervical was also present at the dig site but was destroyed during excavation. Shown in lime.
BYU 12866 and 12867 ("BYU Cervicals"): C5 and C10, respectively. These are some of the few brachiosaur cervicals that are known from the Morrison Formation. Shown in orange.
KUVP 142200, 129724, 133862, 144767, and 129724 ("Bigfoot"): A nearly complete brachiosaur pes found alongside skeletons of Camarasaurus. It currently represents the largest known sauropod pes. Shown in violet.
BYU 9462 ("Ultrasauros macintoshi," Dry Mesa Quarry Material): Originally described as "Ultrasaurus", this scapulocoracoid was referred to Brachiosaurus sp. after "U. macintoshi" was determined to be a chimera of Supersaurus and brachiosaur material. Despite being hailed as the largest dinosaur, BYU 9462 is actually likely smaller than the holotype, scaling its 510 mm coracoid against the holotype’s 540 mm coracoid. Shown in red.
OMNH 01138 ("OMNH Metacarpal"): Known from a single metacarpal originally refered to Camarasaurus. It was later assigned to ‘’Brachiosaurus’’ sp. Based on its gracility. Since the holotype specimen preserves no metacarpals, scaling was done using the Potter Creek specimens. Shown in cyan.
Jensen/Jensen Quarry Material: Among other material, Jensen reports having found a 2.75m long brachiosaur rib. Shown in blue.The scale bar is 4 meters long, with each increment representing 1 meter, scaled to the holotype. White represents known material, light gray and green represent known but inadequately figured material, and dark gray represents unknown material. The human silhouette is from File:Silhouette of man standing and facing forward.svg, which is under CC0.
