Giraffatitan brancai Janensch, 1914

(Da: it.wikipedia.org)
Phylum: Chordata Haeckel, 1874
Subphylum: Vertebrata Cuvier, 1812
Classe: Dinosauria Owen, 1841
Ordine: Saurischia Seeley, 1887
Famiglia: Brachiosauridae Riggs, 1904
Genere: Giraffatitan Paul, 1988
Descrizione
Raggiungeva una lunghezza di 23 m e un'altezza di 12, per un peso totale di circa 50 tonnellate. Altre ossa suggeriscono che possano essere esistiti esemplari ben più grandi con stime di oltre 30 metri di lunghezza, più di 15 di altezza e 100 tonnellate di peso, misure simili a quelle del Sauroposeidon. Come tutti i brachiosauridi, aveva un collo lunghissimo e un aspetto vagamente pendente dato dal fatto che le zampe anteriori erano più lunghe di quelle posteriori. Alcuni paleontologi ritengono che sia, a tutti gli effetti, un sottogenere del più famoso brachiosauro. La famosa ricostruzione del brachiosauro con la testa dotata di un elmo in realtà si basa su un teschio appartenente a un Giraffatitan.
Diffusione
Vissuto in Tanzania nel Giurassico superiore.
