Abstract China is a key area for research into human occupation in the Old World after the initial expansion of early humans out of Africa. Reliable age determinations are pivotal for assessing the patterns of human evolution and dispersal in this region.

Magnetostratigraphic dating of the hominin occupation of Bailong Cave, central China

The Negev Desert in southern Israel hosts a number of late Cenozoic lacustrine and palustrine sedimentary sequences that attest for past wetter conditions in what today constitutes one of the driest deserts on Earth. These sequences are of special importance because the Negev Desert forms part of the Levantine Corridor, which was probably the only continental bridge that enabled initial out-of-Africa expansion of our genus Homo.

Yet, the paleoclimatic significance of these sequences still remains unknown, mainly due to their uncertain late Pliocene to early Pleistocene age.

Here, we report a high-resolution magnetostratigraphic dating of the Shangshazui Paleolithic site that was found in the northeastern Nihewan Basin in The artifact layer is suggested to be located in the Matuyama reversed polarity chron just above the upper boundary of the Olduvai polarity subchron, yielding an estimated age of ca 1. This provides new evidence for hominid occupation in North China in the earliest Pleistocene.

The Nihewan layer has been regarded as Early Pleistocene sediments since it CA ,USA;Magnetostratigraphic dating of early humans in China[A];[C];.

The fluvio-lacustrine sedimentary sequences in the Nihewan Basin, northern China, are important for studying Quaternary land mammal evolution and Paleolithic settlements in the high-latitude temperate East Asia. Here we report new magnetostratigraphic results that constrain age of the Hougou Paleolithic site in this basin. Magnetite and hematite were identified as carriers of the characteristic remanent magnetizations, with the former being dominant. Magnetic polarity stratigraphy shows that the Hougou sequence recorded the very late Matuyama reverse chron and the Brunhes normal chron.

The age of the Hougou Paleolithic site was estimated to be ka based on an averaged rate of sediment accumulation. The combination of our magnetostratigraphy and previously published chronological data for early Paleolithic or human sites in the high-latitude northern China may document a persistent colonization of the hostile high-latitude areas of the eastern Old World during the middle- early Pleistocene.

Hong Ao, Mark J. Here, we report an increased cooling coupled with an intensified aridification for the Xiantai fluvio-lacustrine sequence of Pleistocene age 1. These include the sites of Majuangou 1. However, little is known about the long-term palaeclimatic records retrieved from the Nihewan sedimentary sequences bearing these Palaelithic sites. Magnetic parameters are often determined rather quickly and can be evaluated from almost all rocks.

Like magnetic minerals clay minerals such as chlorite and illite may contain relevant palaeenvironmental information Righi et al. However, the palaeenvironmental significance of these minerals in the Nihewan fluvio-lacustrine sediments has not been systematically investigated yet. In this study, we present a detailed rock magnetic and clay mineralogical investigation on the Xiantai fluvio-lacustrine sequence in the Nihewan Basin, which contains the Xiantai also named Dachangliang stone artefact layer Pei ; Deng et al.

Based on the rock magnetic properties and clay mineralogy of the sediments, we generate a series of independent proxies for Pleistocene palaeclimatic changes in this basin. Comparing our results with data from this basin and the Chinese Loess Plateau, we aim to reconstruct the Pleistocene environmental evolution in this area. Extensive sedimentary exposures consisting of well-developed fluvio-lacustrine sediments of late Cenozoic age are found along the SW—NE trending Sanggan River Fig.

Earlier this month, Scientific Reports included an article by Hong Ao and colleagues reporting a date for the Shangshazui archaeological locality in the Nihewan Basin of North China Ao This is now one of the earliest sites known for human activity in China, possibly the earliest, between 1. The dating of this site is part of a much larger story of archaeological dating in China. Early Pleistocene sites, particularly in the Nihewan Basin west of Beijing, have given rise to a much more detailed paleomagnetic stratigraphy allowing them to be placed more accurately in time.

As a result, China now has several archaeological sites dated to before 1. Majuangou was reported in by Zhu and colleagues Zhu , and was the first of the archaeological sites to break 1.

Add to Favorite Get Latest Update. The Nihewan layer has been regarded as Early Pleistocene sediments since it was named in s. After the Xujiayao paleolithic site was dicovered,the age of the Nihewan layer was extended to the Later Pleistocene and the Nihewan layer in Xujiayao was named Xujiayao Formation which is regarded as the Later Pleistocene type lacustrine sediments. The magnetostratigraphy results of high resolution made recently show that the Matuyama reversed polarity zone is 3 m below the paleolithic layer.

studies conducted using magnetostratigraphy as a prime dating method at (~​e Ma; Ferring et al., ), Gongwangling in China (~ Ma; Zhu Fig. Our preferred interpretation of evidence for the earliest human occupation of.

Several expansions of populations of archaic humans genus Homo out of Africa and throughout Eurasia took place in the course of the Lower Paleolithic , and into the beginning Middle Paleolithic , between about 2. These expansions are collectively known as Out of Africa I , in contrast to the expansion of Homo sapiens anatomically modern humans into Eurasia, which may have begun shortly after 0.

The earliest presence of Homo or indeed any hominin outside of Africa dates to close to 2 million years ago. A study claims human presence at Shangchen , central China, as early as 2. These remains are classified as Homo erectus georgicus. Later waves of expansion are proposed around 1.
