New Evidence of Fishtail Occupation in Northern Perú Greg J. Maggard Keywords: Colonization, late Pleistocene, Andean South America The Fishtail complex is best known from numerous sites identified in the Southern Cone of South America (Chile, Argentina, and Uruguay) (Borerro 2006; Nami 2007; Suárez and López 2 003). Within the Central Andes, however, few sites yielding Fishtail projectile points have been documented. Among these sites are El Inga in Ecuador (Bell 2000; Mayer-Oakes 1986), LaCumbre (Ossa 1976), Laguna Negra (León C. et al. 2004), and two sites in the Chicama Valley in Perú (Briceño 2004). An isolated find in the Piura Alta area of Northern Perú has also been reported (Chauchat and Zevallos 1979). Recent survey of the Quebrada del Batán (Q. Batán) in the lower Jequetepeque Valley of northern Perú (7° 03 49″ S, 79° 24 53″  W) identi fied four additional sites, Je 979 (7° 03 20″ , 79° 24 13″ ), Je 996 (7° 03 28″ , 79° 23 50″ ), Je 1002 (7° 03 32″ , 79° 24 25″ ), and Je 1010 (7° 04 20″ , 79° 25 12″ ), yielding Fishtail points and point fragments (Maggard 2010). The four Q. Batán sites are open-air settings situated on alluvial terraces bordering quebradas (large canyon-like drainages) that provide commanding  views of lar ge ex panses of the drainage floor, intersecting drainages, and the nearby coastal plain. Like the sites in the Chicama and Moche valleys, each of the Q. Batán Fishtail sites also contained projectile points from the contempo- rary or overlapping Paiján complex (Briceño 2004; Ossa 1976). Both the Paiján and Fishtail points were recovered from mixed surface contexts. How- ever, limited excavations at these sites provided data that identify some mate- rials and strata associated with each complex.  Among the four Q. Ba tán F ishtail points, two (from sites Je 9 96 and 1 010) display sharply contracting stems that flare outward at the stem base (concavo- convex), resulting in the classic “fishtail” appearance. The stems are relatively narrow, and the stem base is flat to concave. Lateral edges and stem bases are heavily ground. The other two points (from sites Je 979 and 1002) have broad contracting stems with flat stem bases and ground lateral margins. Only one point, the contracting stem example from site Je 1002, displays fluting on a single face. Raw materials used in the manufacture of the Q. Batán Fishtail points include qua rtz cry sta l (n = 2), chalcedon y (n = 1), and a mottled blue -gr ay c hert (n = 1) (Maggard 2010). Outcrops of quartz crystal occur in the Q. Batán region and likely represent sources of locally acquired materials. The other raw materials (chalcedony and chert) are non-local in origin. The specific sources of these materials are unknown, but most likely are located in the Andean highlands Greg J.

some 35–45 km to the east. A similar pattern of raw material use (local quartzcrystal and non-local fine-grained silicates) was also reported for Fishtail pointsrecovered elsewhere in northern Perú (Briceño 2004; León C. et al. 2004). Incontrast, Paiján points found on these sites are manufactured entirely from

locally available fine-grained quartz, quartzite, and rhyolite. All the documented Fishtail points from northern Perú (Q. Batán, Q. SantaMaria, La Cumbre, Piura Alta, and Laguna Negra) are similar in size (approxi-mately 5–6 cm long). This average length is similar to that of points from sitesin Argentina, Uruguay, and Ecuador, whose length averages 4–7 cm (Bell2000; Nami 2007; Politis 1991, Table 2; Suárez and López 2003). In spite of thesimilarities in size, there is a relatively wide range of morphological variability among Fishtail points within and across different regions. As the points fromthe Q. Batán demonstrate, this appears to be equally true in northern Perú.

Fishtail points from western South America generally date to ca. 11,200–10,100RCYBP (Borerro 2006; Dillehay 2000; Nami 2007). AMS dates from intact deposits at two of the sites in the Q. Batán (Je 996 and 1002) suggest a somewhat more restricted time frame of regional occupation (ca. 11,100–10,600RCYBP).Site Je 1002 yielded an AMS date of 11,014 ± 64RCYBP (AA57942); site Je 996 yielded a date of 10,650 ± 50RCYBP (Beta 185074) (Maggard 2010). Both datesare from wood charcoal samples from buried strata containing lithic debitageand tools of the same non-local raw materials (chalcedony and chert) used inthe manufacture of the Q. Batán Fishtail points. These raw materials are

different from those used in Paiján lithic manufacture and are considered torepresent the Fishtail occupations at these sites. Other artifacts collected fromFishtail contexts included a variety of lithic tools (unifaces, bifaces, and re-touched flakes) and limited faunal remains including South American fox(Psuedalopex sp.), peccary (Tayassuidae), and crab (Decapoda).

Because so few Fishtail sites in northern Perú have been documented, muchless excavated, our understanding of Fishtail occupation in the Central Andesis severely limited. However, data from the Q. Batán sites are refining theregional temporal framework of Fishtail occupation, which appears to have

been more restricted than in other parts of South America. Data from thesesites are also providing important new insights regarding the technological,economic, and mobility patterns of Fishtail groups outside of the more thor-oughly studied areas in the southern cone of South America.
