The Fremont projectile point typology was developed in the 1980s. An early revision combined the Rose Spring Corner-notched and Eastgate Expanding-stem types into a combined Rosegate type with an end date of 900-1000 AD. Some archaeologists recognize that these projectile points persist to approximately 1300 AD but others use the earlier dates. Furthermore, there is a varied approach to these types. Some use the original two types, while others use Rosegate or a combination of Rosegate, Rose Spring, and Eastgate. We used projectile point typology data, illustrations, and photographs to study the temporal range and morphological variation of Rosegate points. We found that Rosegate points are common throughout the Fremont period, with some decline over time. A spatial analysis demonstrates that the points are found throughout the Fremont region but are not evenly distributed. Our morphological analysis does not support the separation of Rosegate points into two distinct types.

Projectile point neck-widths are used to estimate the age of specimens from surface assemblages in southern Idaho. Like other attribute-based dating techniques, it is easier to replicate and can be accomplished with more fragmentary artifacts than more typological-based approaches. Estimating the age in years allows us to examine the past in a more continuous way that avoids problems arising from periodization and discrepancies between archaeologists in their definition of sequences. The availability and physical characteristics of the raw material from which the projectile points were manufactured, along with constraints in scheduling other subsistence resources, may have contributed to the long-term empirical trend toward narrower neck-widths over time. This trend transcends the change in projectile technologies from the earlier atlatl thrown darts to later bow propelled arrows. Both technologies coexisted for at least a millennium in southern Idaho.

Archaic projectile points from the Andean Altiplano exhibit a curious trend of increasing size over time, in contrast to a well-documented size reduction throughout North America. Although a number of hypotheses exist to account for decreasing projectile-point size, there are currently no explicit explanations for increasing size. We consider several hypotheses and interrogate two techno-economic hypotheses. We posit that increasing point size compensated for lost dart momentum or accuracy that resulted from the shortening of atlatls or atlatl darts as wood became increasingly scarce on the tree-sparse Altiplano. We evaluate these hypotheses using a replicated Andean atlatl system in ballistic trials. Contrary to expectation, results show that point enlargement significantly reduces penetration depth, allowing us to confidently reject the momentum hypothesis. Point enlargement, in contrast, tentatively correlates positively with accuracy. Our experiment further shows that camelid bone is an effective and economical alternative to wood for atlatl production. Despite suboptimal lengths, camelid radioulna atlatls have a convenient morphology that requires low production time, which helps explain empirically observed camelid bone atlatls from the Andean highlands. More generally, our observations lead us to consider that central tendencies in archaeologically observed projectile-point size may reflect a trade-off between penetration and accuracy.

This article examines the relationship between rock art and landscape use by pastoral groups and early settled communities in the central Sahara from around 6000 BC to 1000 AD. During this period the region experienced significant climatic and environmental fluctuations. Using new results from a systematic survey in the Wadi al-Ajal, south-west Libya, our research combines data from over 2000 engraved rock art panels with local archaeological and palaeoenvironmental evidence within a GIS model. Spatial analysis of these data indicates a correspondence between the frequency of rock art sites and human settlement over time. However, while changes in settlement location were guided primarily by the constraints on accessibility imposed by surface water, the distribution of rock art relates to the availability of pasture and patterns of movement through the landscape. Although the reasons for these movements undoubtedly altered over time, natural routes that connected the Wadi al-Ajal and areas to the south continued to be a focus for carvings over several thousand years.

AbstractFor many years, small, serrated, obsidian artifacts characteristic of late central California cultural manifestations (Late Horizon), have been regarded as projectile points (arrow and dart points). A functional analysis of a number of these tools based on examination with a binocular microscope revealed evidence of wear patterns including striations which makes it quite clear that these artifacts were used for other purposes. This brings the projectile point interpretation up for serious questioning, at least for the area under consideration. It is suggested that further investigation of artifact assemblages, using similar methods, will in all likelihood alter many existing ideas regarding the functional significance of many artifact types. It is further pointed out that many times discrepancies exist between ethnographic accounts and other sources of data relative to the functional significance of artifacts.

AbstractTypological cross-dating is the primary means by which archaeological sites are placed into chronological frameworks. This approach relies on the assumption that artifacts at undated sites—usually projectile points—are coeval with similar artifacts found at Other, dated sites. While typological cross-dating is necessary in regions dominated by open-air lithic scatters, the approach can be problematic when undated and dated sites are separated by significant distances. Here, we present radiocarbon dates on projectile points with organic hafting material still attached or found within organic storage bags. Our results provide unequivocal ages for various morphological projectile point types at several Great Basin locales and should be useful to researchers seeking local age estimates for those point types, which often involves relying on chronological data from more distant sites. The results also highlight potential issues with uncritically applying typological cross-dating using typologies based on metric attributes, and in two cases, suggest the need to revise the age ranges for certain point styles in the western Great Basin.

Archaeological excavations at the Gault Archaeological Site (41BL323) have revealed an almost complete stratigraphic record of the prehistoric occupation of Central Texas (Collins 2002, 2004). Furthermore, ages obtained from Area 15 of the site confirms good stratigraphic agreement between the diagnostic artifacts, cultural horizons, and stratigraphic units (Rodrigues, et al. 2016; Williams, et al. 2018). This includes some of the earliest evidence for a projectile point technology in North America (Williams, et al. 2018). Like many areas in Central Texas, the combination of water, raw materials, and its position along the Balcones Escarpment provided abundant resources essential to survival. The Gault Archaeological Site has a long history. The site takes its name from a previous landowner, Henry Gault, and the first scientific excavations were conducted there in 1929 under the supervision of J. E. Pearce. In 1990, David Olmstead reported a unique find; an Alibates Clovis point sandwiched between two limestone plaques with engraved geometric designs. This led to a site visit by Dr. Tom Hester and Dr. Michael Collins. This finding was followed in 1997 by the discovery of an extremely fragile mandible of a juvenile mammoth by the Lindsey family. These discoveries prompted the recent archaeological excavations at the site, which began in 1999 and lasted until 2002. As many archaeologists will attest, the most interesting findings came at the very end of the 2002 field season, when archaeologist Sam Gardner exposed cultural material stratigraphically below Clovis in a small test unit. This led to negotiations between Michael Collins and the Lindsey family that resulted in the purchase of the property by Dr. Collins and its donation to the Archaeological Conservancy. Between 2007-2014, Area 15 was excavated to expose the cultural materials below. With the cessation of excavations in 2014, research focuses on reporting these findings and how this early archaeological assemblage in Central Texas is redefining the search for the earliest human occupants of the Americas. The front cover of this issue of the Journal of Texas Archeology and History highlights two specific chronological periods in Texas. Firstly, in each corner you will find interactive 3D scans of four Clovis points that have been recovered from the site (Seldon et al. 2018). In between these, you will find and array of Archaic projectile points that have been recovered from the various excavations conducted between 1999-2002 and 2007-2014. This includes Early Archaic points such as the Hoxie and Martindale; Middle Archaic points including, Kinney and Nolan; and Late Archaic points including Pedernales, Marshall, and Bulverde. Clovis artifacts including, projectile points, blade cores, and diagnostic debitage have been recovered from a total of 9 excavation areas. We will expand on these covers in the future to cover specific research projects currently being undertaken by the Gault School of Archaeological Research staff. The Gault School of Archaeological Research is a non-profit, 501(C)3 charitable organization dedicated to innovative, interdisciplinary research archaeology and education focusing on the earliest peoples in the western hemisphere and their cultural antecedents.

Urban–rural differences seem particularly pronounced in India, especially when based on the official figures provided by the Census of India, which are heavily dependent on the administrative status of settlements. India, one of the world’s most dynamic and populous countries, still possesses an official urbanisation rate lagging well behind other developing economies. To investigate the extent of Indian urbanisation, this article develops a multi-step methodology using indicators specifically conceived for identifying urban structures in India. In this article, an emphasis is given to the conception and to the spatial analysis of two indicators: metropolitan ranking and meta-agglomerations. A method combining these indicators then allows identifying urban macro-structures acting as a larger organising framework in the regional space. Our results show a multitude of different functional areas that have developed specific urban morphologies over time. Some are particularly marked by high values of urban macrocephaly, small settlements taking the shape of nebulae, urban sprawl, etc.
