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. The site includes horse bones with percussion marks, where they were broken for marrow extraction.

Magnetostratigraphic dating of the Hougou Paleolithic site in the Nihewan Basin, North China

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.

This ESR chronology is consistent with the previous magnetochronology, thus providing strong support for the earliest human presence at the high northern latitudes of Northeast Asia. Keywords: Northeast Asia Northern latitudes Early human occupation Introduction The timing of early humans in the eastern Old World is a key issue in the study of early human evolution and migration An and Ho, ; Hou et al. The Nihewan Basin in temperate northern China provides an important source of Paleolithic settlements and therefore early human occupation at high northern latitudes in Northeast Asia, thus serving as an important region for the study of early human evolution and migration Zhu et al.

Therefore, magnetic polarity stratigraphy used to be considered the unique dating method in this region e.

Magnetostratigraphic dating of early humans in China

Perhaps they set out in search of food, or maybe it was simply wanderlust. But at some point early humans left their African homeland and began to colonize other regions of the world. Scientists have only begun to formulate an understanding of the timing of these early migrations. Findings reported today in the journal Nature may thus shed some much-needed light on the matter.

Researchers led by R.

The quality and reliability of the paleomagnetic dates are also evaluated. New magnetostratigraphic results for the Xihoudu Paleolithic site in north-central China.

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. Until the early s, early humans were thought to have been restricted to the African continent in the Early Pleistocene , or until about 0.

Pre- Homo hominin expansion out of Africa is suggested by the presence of Graecopithecus and Ouranopithecus , found in Greece and Anatolia and dated to c. Possibly related are the Trachilos footprints found in Crete, dated to close to 6 million years ago. Australopithecina emerge about 5. Gracile australopithecines Australopithecus afarensis emerge in the same region, around 4 million years ago. The earliest known retouched tools were found in Lomekwi , Kenya, and date back to 3.

The hominin invasion of 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 present a combined sedimentologic, paleontologic and magnetostratigraphic study of one of these sedimentary sequences, the so-called Kuntila Lake sediments, which was carried out at the 30 m-thick Kuntila Gate section in the Nahal Paran basin, southern Israel.

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.

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 earliest hominids are argued to have lived in a habitat of open grasslands mixed with patches of forests close to the bank of the Nihewan paleolake as indicated from faunal compositions. Hominid migrations to East Asia during the Early Pleistocene are suggested to be a consequence of increasing cooling and aridity in Africa and Eurasia. Knowing the precise age ranges of early hominid habitation and stone technologies in different regions of the world is a key component for a comprehensive understanding of human evolution.

It comprises one of the most detailed sets of Early Pleistocene Paleolithic evidence from the whole of Asia1. Therefore, it has become a major area of archaeological research and a prime focus of investigations into early human evolution in East Asia During the past decades, more than 60 Paleolithic sites associated with thousands of in situ Oldowan-like stone tools i. The Nihewan fluvio-lacustrine sediments do not contain material suitable for radio-isotopic dating e.

The exact ages of these Paleolithic sites thus have long been considered controversial. Only recently, reliable ages were assigned to some Early Pleistocene Paleolithic sites based on high-resolution magnetostratigraphy; sites include Majuangou MJG dated at 1.
