Classic Maya civilization in detail Lidar (a type of airborne laser scanning) provides a powerful technique for three-dimensional mapping topographic features. It is proving to be valuable tool archaeology, particularly where the remains structures may hidden beneath forest canopies. Canuto et al. present lidar data covering more than 2000 square kilometers lowland Guatemala, which encompasses ancient settlements (see Perspective by Ford and Horn). The yielded population estimates, measures...
The nature and extent of interactions between the distant regions cultures Mesoamerica remain open to much debate. Close economic political ties developed Teotihuacan lowland Maya during Early Classic period (AD 250–550), yet relationship these continues perplex scholars. This article presents an elaborately painted altar from elite residential group at centre Tikal, Guatemala. Dating fifth century AD, is unique in its display architectural artistic forms, adding evidence not only for...
Abstract This article examines the cultural and ecological history of a single Maya territory from circa 1000 B.C. to A.D. 1100. An ancient is defined as an area land population under jurisdiction particular capital. In addition capital, there are minor centers, household groups, temporary settlements, which together comprise territory. Here, San Bartolo-Xultun in northeastern Department Peten, Guatemala used case study. During more than two thousand years occupation natural landscape...
Travellers naturally prefer to use the most passable routes and establish staging points on way. Cost surface analysis predicts easiest viewshed territory visible from a point or destination. Applying these GIS techniques Buenavista Valley Corridor, our authors write history of travel exchange that vividly reflects rivalry two polities rise fall their nodal settlements.
Lidar reveals the presence of a precinct at Classic Maya city Tikal that probably reproduces Ciudadela and Temple Feathered Serpent imperial capital Teotihuacan.
It has been well over a decade since lidar-based research began in earnest the Maya Lowlands of southern Mexico, Guatemala, Belize, and Honduras. Most investigations have an archaeological focus, with few integrating studies ancient analyses local ecology land-use. A review frequently cited publications reveals lack consistency assessing accuracy feature classifications lidar data variables such as sensor type, class definitions, ground-truthing methods differentially affecting assessment...
Maya conflict left many images. With a few exceptions, however, they reveal limited numbers of victors and captives In contrast, glyphic accounts point to broader convulsions, the challenge remains linking such conflicts infrastructure concerted attack defense. Lidar, technology using laser pulses record model surfaces, does so with aplomb. By now, most Mayanists accept that, in late 4th century A.D., Classic kingdoms became entangled distant polity Teotihuacan, Mexico. Tikal refers that...
Purpose Digital documentation techniques of tunneling excavations at archaeological sites are becoming more common. These methods, such as photogrammetry and LiDAR (Light Detection Ranging), able to create precise three-dimensional models complement traditional forms with millimeter centimeter accuracy. However, these require either expensive pieces equipment or a long processing time that can be prohibitive during short field seasons in remote areas. This article aims determine the...
The research presented in this article tests a methodology for estimating ancient Maya populations through the use of an ISODATA unsupervised classification QuickBird imagery. aim was to expand results ground surveys jungle environments cost-effective manner. lowland Guatemala is composed mosaic vegetation classes and geomorphological catenas. exploited ecological niches present landscape but chose build their residences predominantly on well-drained uplands. Upland terrain can be accurately...
A new paleoecology record from the El Palmar Cival adds to emerging geoarchaeological of Zotz, Guatemala. Palmar's 3 m stratigraphic began in Archaic period before 1500 B.C. at or just initial Maya impacts. From lowest level, Late organic deposition, with evidence for diverse tropical forest and a steady water table, transitioned Early Preclassic clay decreased taxa, three known food more economic species. Clay deposition continued through Preclassic, occasional high charcoal increasing...
Abstract Archaeological tunneling is a standard excavation strategy in Mesoamerica. The ancient Maya built new structures atop older ones that were no longer deemed usable, whether for logistical or ideological reasons. This means as archaeologists excavate horizontal tunnels into structures, they are essentially moving back time. As earlier constructions encountered, these may deviate many directions order to document architectural remains. resultant excavations often become intricate...
Microbial communities are found throughout the biosphere, from human guts to glaciers, soil activated sludge. Understanding statistical properties of such diverse can pave way elucidate common mechanisms ...Multiple ecological forces act together shape composition microbial communities. Phyloecology approaches—which combine phylogenetic relationships between species with community ecology—have potential disentangle but often ...
This article presents three years of archaeological investigations at the minor Maya center Bejucal, Guatemala. A complete site history is presented relying on data from artifact analysis, architectural study, epigraphy, and bioarchaeology, with a goal towards identifying site's function within broader El Zotz polity. The authors argue that Bejucal underwent significant transformation following its establishment as sacred hilltop during Late Preclassic period (400 b.c.–a.d. 250). royal...
