Mapusaurus is similar in size to its close relative Giganotosaurus, with some individuals estimated as over 10.2 metres (33 ft) in length and weighing approximately 3 metric tons (3.3 short tons). The longest individual for which Coria and Currie (2006) provided an estimate is the animal to which femur MCF-PVPH-208.203 belonged; this individual is estimated as 10.2 metres (33 ft) long. Coria and Currie note the presence of isolated bones from at least one longer individual, but do not provide a figure, instead finding the larger bones comparable in size to those from a Giganotosaurus estimated at 12.2 metres (40 ft) in length. Maximum length is thus unknown but greater than 12.2 metres (40 ft). The weight estimate is from another femur (MCF-PVPH-208.234). It was furthermore concluded that the largest remain, a pubic shaft, was 110% the size of the giganotosaurus holotype.
Tyrannotitan Chubutensis
Tyrannotitan is a genus of Carcharodontosaurid from the earlyCretaceous period, discovered in Argentina. It is closely related to other giant predators like Giganotosaurus and Carcharodontosaurus; Its fearsome appearance is reflected in the meaning of its name, "Tyrant titan". Little information has yet been offered about Tyrannotitan. Only a very brief description of the fossils has been published (four pages). The teeth are less blade-like than those of its kin, and possess odd, lumpy denticles (there is a barely distinguishable groove in the center, dividing each denticle into two parts). Unlike known carcharodontosaurids, this animal lacks pneumatically extending into the sacral and caudal centra. The Scapuloid fused, and much better developed than that of Gigantosaorus carolinii, yet the arms are very small.
