Angolatitan
''Angolatitan'' ("Angolan giant") is a genus of sauropod dinosaur from the Upper Cretaceous and the first dinosaur discovered in Angola. Based on a forelimb, it was described in 2011 by Octávio Mateus and colleagues. The only species is ''Angolatitan adamastor''. ''Angolatitan'' was a relict form of its time, being a basal titanosauriform sauropod in a world dominated by the more derived titanosaurs.〔 ==Description== The only specimen is a partial right forelimb, including shoulder blade, upper arm bone, the two bones of the lower arm (ulna and radius), and three metacarpals. These fossils (Field number MGUAN-PA-003) are stored in the ''Museu de Geologia'' of the ''Universidade Agostinho Neto'' in Luanda.〔 The upper arm bone measures , the ulna in length. In general, the forelimb was less robust than in most of the more derived titanosaurs. The metacarpals were slender and equal in length; those of titanosaurs were more robust with varying lengths. Unlike titanosaurs, the olecranon was absent, and the first metacarpal was not bowed.〔
