Mateus, Jacobs, Schulp, Polcyn, Tavares, Neto, Morais & Antunes 2011
Time
Cretaceous Late Turonian

Diet
Herbivore
Fossilsite
Itombe Formation,Tadi Beds, Bengo Province, Angola
Info
Abstract: A forelimb of a new sauropod dinosaur (Angolatitan adamastor n. gen. et sp.) from the Late Turonian of Iembe (Bengo Province) represents the first dinosaur discovery in Angola, and is one of the few occurrences of sauropod dinosaurs in sub-Saharan Africa collected with good chronological controls. The marginal marine sediments yielding the specimen are reported to be late Turonian in age and, thus it represents a non-titanosaurian sauropod in sub-Saharan Africa at a time taken to be dominated by titanosaurian forms. Moreover, Angolatitan adamastor is the only basal Somphospondyli known in the Late Cretaceous which implies in the existence of relict forms in Africa.
Etymology: Angolatitan means Angolan giant. Adamastor was a mythological sea giant from the South Atlantic feared by the Portuguese sailors.
Generic and specific diagnosis: Titanosauriform sauropod with: posteroventral eminence in scapula in the proximal one-quarter, anterior to the acromial ridge; acute medioproximal margin of humerus; and rectangular lateral corner of proximal humerus; proximal outline of the ulna with anteromedial ridge (process); posterior facet of the distal epiphysis of metacarpal I with two small splint-like projections.
Type locality and horizon: Tadi, near Iembe, Tábi community, municipality of Ambriz, Bengo Province, Angola. The precise coordinates of collecting sites are on file at the participating institutions. Tadi Beds, Itombe Formation, Late Turonian (around 90 M.a.), Late Cretaceous.
Material: The material includes a partial right forelimb including the scapula, humerus, ulna, radius and metacarpals I, III, and IV (Table I). All material described here is curated at Museu de Geologia da Universidade Agostinho Neto – PaleoAngola Project, Luanda, Angola (MGUAN-PA), and temporarily registered under field number MGUANPA- 003 (replicas will be housed at Museu da Lourinhã, Portugal, and at Southern Methodist University, USA).
