Abstract

Simple pebble tools, ephemeral cultural features, and the remains of maritime and terrestrial foods are present in undisturbed Late Pleistocene and Early Holocene deposits underneath a large human-made mound at Huaca Prieta and nearby sites on the Pacific coast of northern Peru. Radiocarbon ages indicate an intermittent human presence dated between ~15,000 and 8000 calendar years ago before the mound was built. The absence of fishhooks, harpoons, and bifacial stone tools suggests that technologies of gathering, trapping, clubbing, and exchange were used primarily to procure food resources along the shoreline and in estuarine wetlands and distant mountains. The stone artifacts are minimally worked unifacial stone tools characteristic of several areas of South America. Remains of avocado, bean, and possibly cultivated squash and chile pepper are also present, suggesting human transport and consumption. Our new findings emphasize an early coastal lifeway of diverse food procurement strategies that suggest detailed observation of resource availability in multiple environments and a knowledgeable economic organization, although technologies were simple and campsites were seemingly ephemeral and discontinuous. These findings raise questions about the pace of early human movement along some areas of the Pacific coast and the level of knowledge and technology required to exploit maritime and inland resources.

13. Motifs et procédés : quelques réflexions sur les pierres incisées du site de Gault (Texas central, États‑Unis)

Author

Wernecke, D. Clark and Collins, Michael B.

Abstract

Les pierres gravées représentent une part relativement mineure du patrimoine préhistorique des Amériques (figure). La découverte fortuite en 1990 de quatre pierres gravées dans un contexte ancien au gisement de Gault au centre du Texas (États‑Unis) a suscité un intérêt accru pour ces objets, surtout ceux de plus de 12 000 ans en années calendaires. Les recherches continues à Gault ont permis d’y recenser plus de 100 pierres et de déterminer des attributions allant de l’époque du Paléoindien a...

14. Patterns and Process: Some Thoughts on the Incised Stones from the Gault Site (Central Texas, USA)

Author

Wernecke, D. Clark and Collins, Michael B.

Abstract

Engraved stones have been a comparatively minor part of the reported prehistoric record of the Americas (figure). A chance discovery in 1990 of four engraved stones in an early context at the Gault Site in Central Texas (USA) led to increased interest in these objects, particularly those greater than 12 000 calendar years old. Continued investigations at Gault have documented more than 100 stones from this one site and determined affiliations ranging from Early Paleoindian (ca. 13 000-9 000 c...

Abstract

The transition from Palaeoindian to Archaic societies in North America is open viewed as a linear progression over a brief but time-transgressive period. New evidence from the Wilson-Leonard site in Texas suggests social experimentation by Palaeoindians over a 2500-year period eventually resulted in Archaic societies. The process was neither short nor linear, and the evidence shows that different but contemporaneous lifeways existed in a variety of locales in the south-central US in the Early Holocene. Key-words: North America, Palaeoindian, Archaic, terminal Pleistocene, Early Holocene, cultural transitions, The Wilson-Leonard site in Central Texas (FIGURE 1) provides a record of human occupations spanning ~13,500 years (Collins 1998).

Abstract

BACKGROUND: Coronary calcification inhibits stent expansion. We sought to establish an intravascular ultrasound-derived calcium score to predict stent underexpansion. METHODS: This is a retrospective observational study including de novo lesions that underwent intravascular ultrasound-guided stenting and had maximum superficial calcium angle >270°. Lesions with angiographic calcium not treated with atherectomy or scoring/cutting balloon before stent implantation were randomly divided into derivation and validation cohorts. The end point was stent expansion (minimum stent area/average of reference lumen area) at the maximum calcium site, and stent expansion <70% was considered underexpansion. RESULTS: The morphological characteristics associated with stent underexpansion in derivation cohort were (1) superficial calcium angle >270° longer than 5 mm (regression coefficient, -13.0 [95% CI, -18.1 to -7.8], P<0.0001), (2) 360° of superficial calcium (regression coefficient, -14.2 [95% CI, -22.8 to -5.5], P=0.001), (3) calcified nodule (regression coefficient, -8.3 [95% CI, -14.3 to -2.2], P=0.007), and (4) vessel diameter <3.5 mm (regression coefficient, -9.4 [95% CI, -16.0 to -2.7], P=0.006). The calcium score (0-4) was significantly correlated with poor stent expansion (regression coefficient, -8.1 [95% CI, -10.5 to -5.7], P<0.0001) in the validation cohort as well as in the atherectomy cohort (regression coefficient, -4.8 [95% CI, -7.2 to -2.5], P<0.0001) with significant interaction between validation and atherectomy cohorts (Pinteraction=0.02). In lesions without angiographic calcium, all calcium severity parameters were less than in the validation cohort, and stent underexpansion was observed in only 1.5% (1/67) of lesions. CONCLUSIONS: This intravascular ultrasound calcium score provides the interventionalists with a reliable tool to identify calcified stenoses at risk for stent underexpansion and requiring adjunctive calcium modification before stent implantation.
