Deep inside a limestone cave in southern China, paleontologists have uncovered an assemblage of thirteen fossilized teeth belonging to Gigantopithecus blacki, the largest primate species ever known to have lived. The discovery fills a gap in the fossil record and offers new clues about how the species responded to a dramatic climatic change 1.2 to 0.7 million years ago.<\/p>\n

Gigantopithecus blacki<\/a> is an extinct great ape that once inhabited dense forests of Southeast Asia.<\/p>\n

As its name suggests, this primate was larger than modern gorillas, standing up to 3 m (10 feet) tall and weighing as much as 540 kg.<\/p>\n

The species survived<\/a> from about 2.3 million years ago until its extinction roughly 295,000 to 215,000 years ago.<\/p>\n

Gigantopithecus blacki was first described by the German-Dutch anthropologist Gustav von Koenigswald in 1935, based an isolated tooth he found in a Hong Kong drugstore.<\/p>\n

The fossil record of the species consists of thousands of teeth and a handful of jawbones.<\/p>\n

\u201cGigantopithecus blacki is hypothesized to have been the largest primate species,\u201d said Dr. Yanyan Yao, a paleontologist at Shandong University, Nanning Normal University and the Anthropology Museum of Guangxi, and colleagues from China.<\/p>\n

\u201cIts fossil record is predominantly concentrated in the Early Pleistocene, followed by the Middle Pleistocene, while materials from the Early-Middle Pleistocene transition (1.2 to 0.7 million years ago) remain relatively scarce.\u201d<\/p>\n

The paleontologists found thirteen teeth of Gigantopithecus blacki \u2014 canines, premolars and molars from both the upper and lower jaws \u2014 at Yanli Cave 1 in Chongzuo, China\u2019s Guangxi province.<\/p>\n

The fossils date precisely to the Early-Middle Pleistocene transition (EMPT), a period when Earth\u2019s climate became cooler, drier and more strongly influenced by glacial cycles.<\/p>\n

The age estimate is based not on direct dating of the teeth but on the accompanying animal fossils.<\/p>\n

The researchers identified specimens belonging to 30 species spread across 6 orders, including orangutan relatives, tigers, clouded leopards, tapirs, Javan rhinoceroses, stegodons and Asian elephants.<\/p>\n

Two species within that assemblage were particularly telling for dating purposes: Ailuropoda wulingshanensis, a species of giant panda characteristic of the late Early Pleistocene, alongside Ailuropoda melanoleuca baconi, a subspecies of panda typical of the Middle Pleistocene.<\/p>\n

The co-occurrence of both species is a strong signal that the deposit formed precisely during the transition between those two epochs.<\/p>\n

\u201cThe faunal assemblage indicates a biostratigraphic age of EMPT,\u201d the researchers said.<\/p>\n

The Gigantopithecus blacki teeth from Yanli Cave 1 also appear to capture an evolutionary shift in progress.<\/p>\n

Some specimens retained the relatively small tooth sizes typically seen in earlier populations, while others approached the larger dimensions common among later populations \u2014 a trend presumably linked to dietary adaptation.<\/p>\n

\u201cComparative analysis of tooth dimensions with Gigantopithecus fossils from other localities reveals that some specimens from Yanli Cave 1 retain the relatively small-sized characteristic generally found in the early Early Pleistocene populations,\u201d the scientists said.<\/p>\n

\u201cHowever, other specimens approach the large dental size commonly found in the late Early Pleistocene populations and larger size ranges documented in the Middle Pleistocene populations.\u201d<\/p>\n

\u201cThese findings are consistent with the biochronological assessment.\u201d<\/p>\n

\u201cFollowing the discoveries at Queque Cave and Zhanwang Cave (both located at Chongzuo, Guangxi), Yanli Cave 1 represents as a third potential EMPT Gigantopithecus locality, likely offering crucial evidence for understanding dental evolutionary patterns and adaptive strategies in response to EMPT climatic shifts.\u201d<\/p>\n

The findings were published in the journal Acta Anthropologica Sinica<\/a>.<\/p>\n
