Unifacial beveling on alternate edges appear simultaneously in NA and CA around 12, BP suggesting some transmission of knowledge related to this technological feature but more data from both stratified sites with bifacial stone tools and ancient DNA are needed to fully test these propositions. The Lowe tradition is a technological lithic complex unique to southern Mesoamerica.

It shares features with contemporaneous stemmed point types found primarily in tropical areas of SA and lower CA, but is also related to ancestral Paleoindian complexes in NA. Its development corresponds with a pattern of regionalization and diversification reflected in similar age tools found throughout the Americas [ 98 ] at a time of changing Holocene environments.
Links to NA are complicated by a dearth of supporting data on early technocomplexes from the large geographic space encompassed by most of central and southern Mexico, making it hard to find evidence for lateral cultural transmission of technological knowledge from NA to southern Mesoamerica. Lowe complex tools are basally thinned, stemmed, and barbed bifaces. They are a flexible tool type well suited for the diverse set of early Holocene environments like those that emerged in Belize.
In particular, tropical forests offered new resources that were of economic importance including a wide variety of palms, tubers, and vines [ 99 , ]. Broad-spectrum plant and animal-based economies were likely well in place in the late Paleoindian period in CA [ ], much like they were in SA [ 62 , ].
Comparative data from Chiapas in southern Mexico suggest flaked stone tools of late Paleoindian age were used for plant and wood processing [ ] similar to proposed diversified plant-based economies in lower CA [ , ] and SA [ ]. We provide a chronology for the Lowe complex that is potentially years long, far exceeding any existing New World Paleoindian technocomplex.
Unifacial beveling on alternate edges, not found on other South or Central American points and not found on earlier Clovis or lanceolate types, may be the earliest characteristic of Lowe complex. Our biface tip from TY dates to calBP 12,—12, and is steeply beveled. This suggests that Lowe type bifaces were manufactured over a shorter time-period, while the overall complex that includes opposite edge beveling technology of large bifaces in Central America may have lasted significantly longer, though it is less clearly defined.
In this paper we argue that the Late Paleoindian period is a time of diversification in tool types as an adaptation to the range of environmental conditions found in southern Mesoamerica as well as increasing reliance on plant resources, and that this specialization is a feature you see very early on in the occupation of the neotropics, and likely in adjacent regions of South America. Further, our understanding of Paleoindian subsistence will be enhanced with more detailed analyses of other stone tools from these assemblages, including grinding, chopping, and cutting tools made of non-chert resources.
These studies accompanied by macrobotanical and residue analyses will clarify the range of subsistence resources exploited by early settlers. This reappraisal of the chronology of Lowe complex fills an important gap in the prehistory of southern Mesoamerica, a particularly diverse resource rich tropical landscape. It is also the first securely dated Paleoindian tool for this region. In southern Belize formal bifacial tools are not present in Archaic assemblages, as is the case for El Gigante [ 85 ]. This is again in stark contrast to NA with its robust Archaic technocomplexes. Southern Mesoamerica again looks a lot more like its tropical neighbors to the south [ ], suggesting little lateral technological transmission from NA to the tropics across this time period.

Abstract From the perspective of Central and South America, the peopling of the New World was a complex process lasting thousands of years and involving multiple waves of Pleistocene and early Holocene period immigrants entering into the neotropics. Data Availability: All relevant data are within the manuscript. Introduction Lack of knowledge of the Paleoindian period in southern Mesoamerica, a critical early migration bottleneck, has impeded our understanding of the peopling of the Americas and how early New World migrants adapted to emergent tropical environments.
Download: PPT. Paleoindian chronologies in southern Mesoamerica In southern Mesoamerica even rudimentary absolute chronologies dating Paleoindian and Archaic period stone tools are lacking. Reassessing the chronology of the Lowe complex Since the s Lowe, and a suite of technologically similar bifaces, have become synonymous with the Late Archaic 4,—3, BP. Results We present results of excavations at two rockshelters in southern Belize where we recovered Paleoindian artifacts from well dated stratigraphic contexts.

Discussion At the end of the Pleistocene, bifacial stone tool technologies were widespread across the New World [ 28 , 62 ]. Population structure, gene flow, and technological diffusion Transmission of Paleoindian stone tool techno-knowledge from NA to CA and SA has been proposed and discussed [ 82 ] but can now be informed by paleogenetic studies which demonstrate the timing and structure of waves of humans migrating from NA into and through the bottleneck of CA, then colonizing SA [ 1 , 58 ].

The 12th and 13th century Aztec Ruins National Monument, a large pueblo which was possibly founded by Chacoan migrants soon after the abandonment of the Chaco Canyon region, has been only partially excavated. Located at Aztec, New Mexico, it has at least 28 kivas, including a restored great kiva. Aztec is open daily from a. Chimney Rock, a ruin perched on a foot high ridge in south central Colorado, about 17 miles west of Pagosa Springs, may have served as a place of Chacoan spirituality and lunar observations.
It lies in the shadows of a pair of towering pinnacles, "Chimney Rock" and "Companion Rock," which had evident ritual significance. It consists of Chacoan-style living quarters and ceremonial chambers as well as a number of earlier ruins. It is open for four scheduled guided tours daily from May 15 through September Box Pagosa Springs, Colorado Phone or during off season.
The Mesa Verde National Park entrance half way between the communities of Cortez and Mancos has seven major 12th and 13th century ruins sequestered in alcoves of canyons, and it has many other ruins, some of them thousands of years old, located on the tops and flanks of the mesa. Through the restorations of ruins and the museum exhibits and dioramas of prehistoric life in Mesa Verde, the National Park Service has constructed an excellent overview of the sequence of Native American cultural developments in the Southwest.
Mesa Verde is open every day of the year, with ranger-guided tours for some of the ruins and self-guided tours for other ruins. The most striking features of the ruins are the towers, some square in floor plan, others roughly circular, some singular, a few paired. The towers served an unknown purpose.

The Canyon de Chelly National Monument, a monumental natural sculpture in red sandstone, encompasses several major 12th and 13th century Kayenta cliff dwellings and perhaps small village sites.
Its Native American history extends continually from early pit house farmers through the Kayenta Puebloan period into modern Navajo occupations. The visitor center, at Chinle, Arizona, is open from a. Navajo concessionaires offer daily guided jeep tours through the canyon. Unlike the ruins at Chaco Canyon, Mesa Verde, Hovenweep and other locations, the fragile ruins of Canyon de Chelly cannot be entered by visitors. Tsegi Canyon, part of the Navajo National monument, has two major 13th century ruins, Betatakin and Kiet Siel, the largest and best preserved cliff dwellings in Arizona.
Two fairly strenuous hikes, guided by National Park Service rangers, are required to reach the ruins, although Betatakin can be viewed from an overlook. The 5-mile, 5-hour hike to Betatakin, limited to 25 people, begins at a. The mile overnight hike to Kiet Siel, limited to 20 people, can be joined through reservations only. The hikes are conducted from Memorial Day to Labor Day.

Sinagua Pueblo Sites North Central Arizona The Sinagua people evidently descended from Yuman hunting and gathering ancestors and drew culturally from various Puebloan traditions. They built the three-story Wupatki now partially restored and several neighboring pueblo villages near the Sunset volcanic crater northeast of Flagstaff in the 11th and 12th centuries.
Part of the Wupatki National Monument, the pueblo ruins are open from sunrise to sunset.

A major trade and ritual center, Paquime would become the largest, most influential community in the entire desert region for the next two centuries. It included, not only a major apartment complex and an apparent outdoor market and trade center, but also ceremonial mounds and ball courts.
For those unaccustomed to traveling in Mexico, I recommend that you contact a travel agent, preferably one with representatives in the desert Southwest, for additional information about visiting Paquime. Late Prehistoric and Historic Puebloan Sites By the middle of the second millennium, the Puebloan people had largely abandoned their ancestral homes in the northern Chihuahuan Desert, the northern Sonoran Desert and the Colorado Plateau.
While some apparently reverted to the late Desert Archaic hunting, gathering and casual farming lifestyle in their traditional lands, most migrated to aggregated pueblos in the upper Rio Grande drainage basin, west central New Mexico and northeastern Arizona. When the Spanish conquistadores arrived in the deserts of the Southwest in the 16th century, they discovered about communities with thriving Puebloan populations and numerous others, abandoned decades earlier, with walls still standing.
Abuses by Spanish colonists, diseases from Europe, and incessant raiding by Apaches and other tribes triggered new abandonments. All that remain today are 19 living pueblos in New Mexico and the Hopi pueblos in northeastern Arizona. Fortunately, several of the living pueblos share their heritage with visitors. For instance, Acoma, the spectacular crown of a mesa about 70 miles east of Albuquerque, offers tours of the ancient village and invites visitors to its annual Harvest Dance and Annual Feast of San Estevan.
Similarly, the Hopi, with villages located at the base and on the top of three mesas, offer tours and share some events. A number of pueblos abandoned in late prehistoric times or after Spanish colonization are open for tours and visits. Some of the more spectacular late prehistoric ruins include the 15th century two-story Tyuonyi Pueblo along with numerous other ruins located in Frijoles Canyon in the Bandelier National Monument in north central New Mexico and the 13th through 16th century room Puye Pueblo plus numerous other ruins located at the mouth of Santa Clara Canyon near Espanola, New Mexico.
Among the most impressive historic ruins, with Spanish mission church walls still standing, include Pecos, about 15 miles east of Santa Fe, and the Salinas Pueblos Gran Quivira, Quarai and Abo , near the community of Mountainair, New Mexico. Main Street Farmington, New Mexico Phone or Other Sites to See While the Puebloans recall their village and farming heritage, the other tribes stage traditional dances, ritual celebrations, intertribal powwows, feasts, fiestas, games, rodeos, beauty pageants, street fairs and arts and crafts festivals.
