Gigantopithecus
Gigantopithecus (from the Ancient Greek ' "giant", and ' "ape") is an extinct genus of ape that existed from perhaps nine million years to as recently as one hundred thousand years ago, at the same period as "Homo erectus" would have been dispersed, in what is now India, Vietnam, China and Indonesia placing "Gigantopithecus" in the same time frame and geographical location as several hominin species. The primate fossil record suggests that the species "Gigantopithecus blacki" were the largest known primates that ever lived, standing up to and weighing as much as , although some argue that it is more likely that they were much smaller, at roughly in height and in weight.
Largest prehistoric animals
There is much controversy over the largest-known of these reptiles. Fossil remains of a pliosaur nicknamed as "Predator X" have been discovered and excavated from Norway in 2008. This pliosaur has been estimated at in length and in weight. However, in 2002, a team of paleontologists in Mexico discovered the remains of a pliosaur nicknamed as "Monster of Aramberri", which is also estimated at in length. This species is, however, claimed to be a juvenile and has been attacked by a larger pliosaur. Some media sources claimed that "Monster of Aramberri" was a "Liopleurodon" but its species is unconfirmed thus far.
Another very large pliosaur was "Pliosaurus macromerus", known from a single incomplete mandible. It may have reached , assuming the skull was about 17% of the total body length.
