Fight Day stats

37’ 1" long (11.3 m)

Weighed in at 4 tons (8,533 lbs, 3871 kg)



Mapusaurus is known from a bonebed with at least 9 individuals.  Bonebeds are not common and meat-eating bonebeds containing only one type of predator are extremely rare.  This one contained only Mapusaurus bones representing various sized individuals, from juvenile to at least one individual that met, or exceeded, the size of Giganotosaurus!  Being a carcharodontosaurid means Mapusaurus had a long, low skull full of 2”, highly serrated, teeth, powerful hands with 4” claws, and strong legs.  Though ranked only #13, Mapusaurus definitely has the tools to beat a higher-ranked opponent!
