Info
Genus - Typespecies
Holotype
MPEF-PV 1156 (Museo Paleontológico Egidio Feruglio, Trelew): Partial dentaries, isolated teeth, dorsals 3–8 and 11–14, proximal caudal vertebra, isolated ribs and haemal arches, incomplete left scapulocoracoid and right humerus and ulna; pubes, ischia, and fragments of left ilium; almost complete left femora, fibula and metatarsal II.
Paratype
MPEF-PV 1157: jugals, right dentary, isolated teeth, atlas, cervical 9?, dorsals 7?, 10 and 13, partially preserved fused centra of sacrals 1–5, isolated distal caudals, ribs, right femur, incomplete left metatarsal II, pedal phalanges 2.I, 2.II, and 3.III. Paratype specimen is approximately 7% larger than that of the holotype.
Etymology
Latin words tyrannus (tyrant) and titan (giant), the specific name from the Chubut province, Argentina.
Known from two individuals. Dentary 68 cm long and 14 cm deep at its rostral end, deep, squared off symphyseal region, with a ventral process or chin, as in Giganotosaurus. Postaxial cervical vertebrae are strongly opisthocoelous. Presacral vertebrae bear well developed pneumatic foramina and fossae...... humerus and ulna ....indicate that forelimbs were short and robust... Hindlimb bones are also massive, The femur of MPEF-PV 1157 estimated length of 140 cm is slightly shorter than that in Giganotosaurus (143 cm; Coria and Salgado 1995). The transverse width of the femoral shaft of Tyrannotitan is 16.5 cm.
