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.

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.

Situated at the base of the coastal cliffs, this association is characterized by many land mammals, trace fossils indicative of the Psilonichnus Ichnofacies, and irregularly distributed oyster bioherms. The age of onset of hyperaridity in the Atacama Desert, Chile, which is needed to validate geological and climatological concepts, has been heretofore uncertain.
Before discussing Miocene apes, a few terms must be defined. Prior to the revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian stage, which lasted from 2.

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.
It means the age of the Nihewan layer at Xujiayao and the paleolithic layer within it can not be the Later Pleistocene in age. It should be the same as the traditional Nihewan layer ranging in age from Early Pleistocene to Early Middle Pleistocene. Vandenberghe 3 G. Mingaars 3 and J.
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.

Archaeological deposits were buried rapidly in primary context within shallow lake margin deposits, with only minor post-depositional disturbance from relatively low energy hydraulic forces. The FL lithic assemblage is characterized by a core and flake, Oldowan-like or Mode 1 technology, with a low degree of standardization, expedient knapping techniques, and casually retouched flakes. The bone assemblage suggests that hominin occupation of the FL site was in an open habitat of temperate grassland with areas of steppe and water.
The main features of the FL assemblage are discussed in the context of the early Pleistocene archaeology of Nihewan, for which an assessment of current and future research is also presented. The earliest dispersal of hominins out of Africa constitutes a central issue in modern Paleoanthropology [ 1 — 3 ]. In addition to the probable southern route through Arabia and Southeast Asia [ 14 — 16 ], another plausible dispersal corridor could have included a northern route from Dmanisi through Mongolia, reaching the Nihewan Basin in northern China [ 9 , 11 , 17 ].
Nihewan early Pleistocene stone artifact assemblages have been described as technologically simple, and characterized by an apparently non-economical use of raw materials, generally informal artifacts and rare occurrence of retouched flakes [ 15 , 25 — 28 ].
Magnetostratigraphic dating of early humans in China
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.

Xiaochangliang XCL , located in the Nihewan Basin of North China, is a key archaeological locality for understanding the behavioural evolution of early humans. XCL dates to ca. Here we describe the lithic assemblages from XCL, providing information on stone tool reduction techniques and the influence of raw materials on artefact manufacture. The XCL hominins used both bipolar and freehand reduction techniques to manufacture small flakes, some of which show retouch. Bipolar reduction methods at XCL were used more frequently than previously recognized.
Comparison of XCL with other Early Pleistocene sites in the Nihewan Basin indicates the variable use of bipolar and freehand reduction methods, thereby indicating a flexible approach in the utilization of raw materials. The stone tools from XCL and the Nihewan sites are classifiable as Mode I lithic assemblages, readily distinguished from bifacial industries manufactured by hominins in Eastern Asia by ca.

The Nihewan Basin in North China is one of the most important palaeoanthropological archives in Asia as it preserves an abundance of mammal fossils and stone tool assemblages in a number of localities e.
Although hominin fossils have not been recovered from the Nihewan Basin as of yet, early human activities are well represented by tens of thousands of stone tool artefacts [ 5 ]. XCL was the first Early Pleistocene archaeological site discovered in the Nihewan Basin, and thus regarded as a milestone in human evolutionary studies in China, particularly for understanding the expansion of early hominins to high latitudes. Since its original discovery in , a series of field investigations and archaeological excavations have been conducted at XCL, leading to the recovery of fossils and stone artefacts.

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. Zhu of the Chinese Academy of Sciences in Beijing have dated a large assemblage of stone tools excavated from northern China’s Nihewan Basin at 1.
