Brachiosaurus brancai

The skeleton of Brachiosaurus brancai from Tendaguru in Tanzania is 13.27 metres tall and the largest mounted dinosaur skeleton in the world.

The skeleton was rebuilt between 2005 and 2007, taking into account recent scientific findings. Now, the strikingly long arms (Brachiosaurus means "arm lizard“) are fully extended to bear the full body weight. The neck is erect to alleviate stress in the neck vertebrae.

Enormous Weight
According to the latest calculations, its body mass must have been approximately 50 tonnes - the rough equivalent of eight elephants The histological analysis of bones showed that sauropods grew very fast and reached maturity at 10 to 15 years. This extraordinary growth in such a short time could only be achieved by a constant supply of energy from plants.

The Skull
The well preserved Brachiosaurus skull was a sensational find. It is very rare that a completely preserved dinosaur is found. The copy of the head shows a prominent crest, which might have served as a resonance chamber or to warm up inhaled air.

Brachiosaurus and numerous other finds from the Tendaguru-Expedition have remained a focus of interest at the Museum für Naturkunde. New methods and interdisciplinary cooperation help shed more light on the existence of these unusual animals.
