Advanced maritime technology associated with long-distance exchange and intensified resource acquisition has been linked to the development of stratification and greater sociopolitical complexity in the Pacific Rim region. One such example is the emergence of hereditary chiefs among the Chumash Indians of southern California. Plank boats owned by an elite group of wealthy individuals and chiefs were an integral part of an elaborate economic system that was based on maritime exchange. An artifact assemblage associated with the construction, maintenance, and use of this watercraft was identified and analyzed. It included wooden planks, asphaltum plugs, asphaltum caulking, and chipped stone drills. Radiocarbon dates and other relative-dating techniques provide strong evidence that the plank canoe originated at least 1,300 years ago in southern California. This represents the earliest use of this type of watercraft in North America and probably in the New World. The timing of this innovation provides evidence that sociopolitical complexity developed in the region at least 500 years earlier than previously proposed.

Fluted Points

This paper examines geographic variation in fluted point morphology across North and South America. Metric data on 449 North American points, 31 Central American points, and 61 South American points were entered into a database. Ratios calculated from these metric attributes are used to quantify aspects of point shape across the two continents. The results of this analysis indicate gradual, progressive changes in fluted point outline shape from the Great Plains of western North America into adjacent parts of North America as well as into Central and South America. The South American “Fishtail” form of fluted point is seen as the culmination of incremental changes in point shape that began well into North America. A geographically gradual decline in fluting frequency also is consistent with the stylistic evolution of the stemmed “Fishtail” points. Although few in number, the available radiocarbon dates do suggest that “Fishtail” fluted points in southern South America are younger than the earliest dates associated with Clovis points in western North America. All of these data converge on the conclusion that South American “Fishtail” points evolved from North American fluted points.

Two new Pertusaria species with brown ascospores are described from southern California and Baja California, Mexico. Pertusaria islandica sp. nov. is characterized by pertusariate to pseudolecanorate ascomata, ellipsoid ascospores, 8-spored asci, a strongly K+ violet reacting epithecium, and the presence of the 2′-O-methylperlatolic acid chemosyndrome, while P. occidentalis sp. nov. has pertusariate ascomata, globose to subglobose ascospores, 8-spored asci, and contains the arthothelin chemosyndrome. Pertusaria ochracea Kremp. is reduced to synonymy with P. melanospora Nyl.

The chronologic record of late Quaternary biota from central Alberta has broad implications for understanding the archaeological, geological, paleontological, and paleoenvironmental record of western North America. Radiocarbon dates on remains of Pleistocene megafauna were previously used as proxies for the advance and retreat of ice sheets across Alberta (e.g. Young et al. 1994; Dyke 2005), and are important for understanding landscape changes that likely influenced the timing of human dispersal into North America (Burns 1996). 14C records of Holocene age continue to refine our understanding of landscape change leading up to modern environmental conditions (Beaudoin 2003). Here, we report 15 14C dates from new and previously recorded sites in central Alberta, and one from just across the border within Saskatchewan (Figure 1).

AbstractIn western North America, the milliped order Callipodida is represented by the Colactidini, Tynommatini stat. n., and Diactidini tribus n., in the subfamily Tynommatinae, family Schizopetalidae; a coordinate tribe, the Texophonini, occurs on the Gulf Coast of south Texas. The Tynommatini consists of two genera and four species: Tynomma mutans (Chamberlin), T. magnum Buckett & Gardner, and T. gardneri sp. n., occurring around Monterey and San Pablo/San Francisco Bays, California, and Idrionaria dineh gen. n. & sp. n., in Washington County, Utah. The Colactidini ranges from Durango, Mexico, to central Utah and California east of the Sierra Nevada, with disjunct areas in southern California and Baja California, the latter extending northward to metropolitan San Diego. It is represented by two genera and 6 species: Colactis Loomis: C. tiburona (Chamberlin), utorum (Chamberlin), and protenta and quadrata, both by Loomis; and Heptium Loomis: H. carinellum and scamillatum, both by Loomis. The Diactidini, occupying coastal southern California and the adjacent fringe of Baja California, is comprised of three genera and 10 species: Diactis Loomis: D. soleata, triangula, and frondifera, all by Loomis, and amniscela, cupola, jacinto, procera, and strumella, all spp. n.; Florea sinuata gen. n. & sp. n.; and Caliactis bistolata gen. n. & sp. n. The following new synonymies are proposed: C. yuma Chamberlin, sideralis Loomis, and loomisi Hoffman under C. tiburona; C. briggsi Shear and saxetana and baboquivari, both by Loomis, under C. utorum; H. canum Chamberlin under H. carinellum; and Etiron paroicum and pearcei, both by Chamberlin, under D. triangula and T. mutans, respectively. The eastern Nearctic callipodid fauna is summarized and significant new localities are reported; Tetracion antraeum Hoffman, stat. n., is elevated from a subspecies of T. jonesi Hoffman.

Coastal Adaptations

As stated in our original paper (Jones et al. 2002), the Cross Creek site is not of sufficient antiquity to challenge Clovis for temporal priority in western North America, but it pushes the age of the California Milling Stone culture back 2,000 years earlier than previous estimates. The Milling Stone culture and coastal adaptations on the southern California islands are so profoundly different from Clovis that they beg consideration of alternative colonization scenarios. Relying on old arguments and ignoring recently published findings, Turner (this issue) argues that there is insufficient evidence for a maritime culture on the central coast of California at the end of the Pleistocene. In our response, we further discuss implications of the findings from Cross Creek and other studies that support a coastal migration model.

The Occurrence and Significance of Southwestern Grooved Axes in California

Unfamiliar Object

To the archaeologist whose primary field of endeavor is California, the grooved stone ax is a relatively unfamiliar object, since it occurs but rarely either in the course of excavation or in the perusal of the literature. That the grooved ax occurs at all in this region is significant, chiefly for the reason that in western North America it is a form highly characteristic of, and, with few exceptions, restricted to the Southwestern culture province proper. Since southern California is generally considered a western peripheral extension of the Southwestern culture area, it is not surprising occasionally to encounter the grooved ax here. It is interesting to note that this implement also occurs far to the northward in central and northeastern California, a region commonly thought to be beyond the zone of direct influence by or immediate contact with the Southwest proper. Presumably the grooved ax in central and northern California represents an extreme northwesterly extension from its native locale, which we assume to be the Southwest.
