MEET THE ANIMAL
Meet Giraffatitan
Giraffatitan was a plant-eating sauropod from Late Jurassic Tanzania. Its fossils are associated with Tendaguru, and the Berlin exhibit offers a familiar picture of its enormous body. A museum length reference introduces its scale without identifying one complete measured individual. [D4]
The museum describes a remarkably long neck, small head and column-like limbs. Together these features outline a terrestrial sauropod whose bulk was supported above the ground. A display makes those proportions easy to appreciate, while a mounted pose still includes choices about missing anatomy. [D4]
The towering Berlin skeleton combines bones from several animals and restored parts. Its original name-bearing specimen is a skull and front-neck skeleton, not the entire mounted display. Keeping that distinction visible explains what identifies the dinosaur and what information was assembled to produce the full reconstruction. [D2]
Researchers estimated the mass of the mounted composite using laser scans and a model calibrated with mammals. The result applies to that reconstruction, rather than a weighed animal or an adult population. A spectacular display can be a useful research subject while still requiring careful explanation of its restored pieces. [D3]
PREHISTORIC ANIMAL DOSSIER
A life in profile.
The animal, the evidence, and the questions still open.
Long forelimbs, a deep chest and an extended neck gave this brachiosaurid distinctive proportions. Fossil anatomy supports its separation from Brachiosaurus. [D1]
Profile scope: Genus profile centered on Giraffatitan brancai from Tendaguru. The North American Brachiosaurus altithorax is a separate taxon; the Berlin mount combines individuals. [D2]

How to read the evidence
Source supported identifies a description documented by the cited source. Inferred marks a reconstruction or functional estimate. Debated marks competing interpretations. Not established means the sources reviewed for this dossier do not support a firm conclusion; it does not mean a behavior never occurred.
A size reference is an estimate, not a population range. Nesting evidence does not by itself establish courtship, mate choice, or lifelong pairing.
Body mass
InferredAbout 23.2 tonnes; mounted-composite model
Sellers’ laser-scan model uses a minimum convex hull and a correction calibrated on mammals. Its subject is the Berlin reconstruction, not a single fossil animal or an adult population. [D3]
Diet
InferredPlants
The museum identifies herbivory. Long forelimbs and neck are compatible with elevated browsing, but neither a fixed feeding height nor a specific plant menu is established here. [D4]
Habitat & fossil setting
InferredTendaguru coastal plains
The formation records coastal and tidal plains alternating with shallow marine deposits. These sediments reconstruct a regional setting, not evidence that Giraffatitan lived submerged; its reviewed material is Late Jurassic. [D5] [D4]
Movement
InferredFour-legged terrestrial walker
The skeleton’s weight-bearing limbs and unusually long forelimbs support quadrupedal reconstruction. Habitual neck angle and walking speed are not directly measured by a museum mount. [D1]
Distinctive anatomy
Source supportedLong forelimbs and high shoulders
Comparison with Brachiosaurus finds differences in the trunk, tail and limb proportions. The familiar African skeleton should not supply interchangeable measurements for the American genus. [D1]
Reproduction & life together
Reproduction & nesting
Not establishedNot established here
Reviewed genus-specific research does not establish clutch size, nesting arrangement, incubation behavior or parental care. Broader sauropod nesting discoveries cannot supply those details.
Courtship & mating
Not establishedNot established here
Focused searches and reviewed anatomy do not establish mate choice, displays or sex-specific coloration. Comparisons with living giraffes are not direct dinosaur evidence.
Social behavior
Not establishedNot established here
Numerous Tendaguru specimens are known, but the reviewed sources do not establish persistent herds or the relationships between the individuals used in the mount.

THE STORY IN THE FOSSILS
Meet Giraffatitan.
The towering Berlin reconstruction brings together bones from several animals. The actual holotype is MB.R.2180, a skull and anterior neck skeleton; the larger MB.R.2181 is referred material, rather than a valid lectotype. [2]
Separating Giraffatitan from Brachiosaurus makes the catalog more informative: their similar silhouettes conceal distinct trunk, tail and limb proportions. [1]
A note on scale and time
The dossier identifies the scope of each reference estimate. A mount, an individual fossil and a species-wide adult range are different measurements. Comparison metrics remain unavailable where adult scope has not been established. Unknown does not mean zero.
