Tool Types

The Holzman archaeological site, located along Shaw Creek in interior Alaska, contained two mammoth ivory rods, of which one is bi-beveled, within a stratigraphically sealed cultural context. Dated 13,600–13,300 cal BP, these are the earliest known examples of osseous rod technology in the Americas. Beveled ivory, antler, and bone rods and points share technological similarities between Upper Paleolithic Europe, Asia, eastern Beringia, and the Clovis tradition of North America and are important tool types in understanding the late Pleistocene dispersal of modern humans. The Holzman finds are comparable to well-known Clovis tradition artifacts from Anzick (Montana), Blackwater Draw (New Mexico), East Wenatchee (Washington), and Sherman Cave (Ohio). We describe these tools in the broader context of late Pleistocene osseous technology with implications for acquisition and use of mammoth ivory in eastern Beringia and beyond.

Lercaritubus problematicus Flügel, Senowbari-Daryan, and Di Stefano, 1990, a problematic organism, was initially described from Lower and Middle Permian rocks of Sicily, was subsequently recognized in Upper Permian reefs of Oman and reefal limestones of the Tethyan realm. It is here described for the first time from North America, from the Middle Permian reefoidal Upper Capitan Limestone of the Guadalupe Mountains in New Mexico. Lercaritubus problematicus has a stratigraphic range of Lower to Upper Permian and occurs widely in Permian tropical reef deposits.

The four North American species of Evernia, E. divaricata (L.) Ach., E. mesomorpha Nyl., E. perfragilis Llano, and E. prunastri (L.) Ach., are discussed from the standpoint of taxonomy, distribution, and ecology. The North American distributions of E. divaricata and E. perfragilis are mapped for the first time. A puzzling lichen found on the ground in alpine areas from New Mexico north to Alberta is regarded as an ecological variant of E. divaricata.

AbstractRadiocarbon dating of closely associated marine mollusk shells and terrestrial material (mammal bones or charred wood) collected from archaeological contexts in northern Atlantic Iberian coastal areas is used to quantify the marine 14C reservoir effect (ΔR) for the coastal waters off the Cantabrian coast of northern Iberia. For the first time, ΔR values were reliably determined for these coastal waters and, also for the first time, a ΔR was calculated for the Late Pleistocene in Atlantic Iberia. Pairs of coeval samples of different carbon reservoirs selected from Upper Paleolithic (Late Pleistocene) and Mesolithic (Early Holocene) contexts yielded ΔR weighted mean values of –117±70 14C yr and –105±21 14C yr, respectively. These values show oceanographic conditions characterized by a reduced offset between atmospheric and surface water 14C contents, suggesting a nonexistent or very weak upwelling and some stratification of the water column. Similar oceanographic conditions have been recorded in other areas of Atlantic Iberia during the Holocene, such as off Andalusian and northwestern Galician coasts. Results not only provide useful information on environmental conditions but also a framework to obtain more precise and reliable absolute chronologies for the Late Pleistocene and Early Holocene in northern Iberia.

The tribe Stenochiini Kirby, 1837 comprises six genera in North America with most species occurring in the tropical and temperateregions of the continent. Only two species in the genus Strongylium Kirby, 1818 have previously been reported from west of theContinental Divide in the United States from Arizona and New Mexico and no members of the tribe have been reported from the stateof Sonora, Mexico. We here report Strongylium tenuicolle (Say, 1826), known to be widely distributed east of the Rocky Mountains,from west of the Continental Divide for the first time from both Arizona and New Mexico. We similarly report the first records ofboth Strongylium apache Triplehorn and Spilman, 1973 and Strongylium atrum Champion, 1888 from Sonora. Oploptera chamelensis(Doyen, 1990) was previously known only from the type series from Jalisco, Mexico and is here reported from Sonora, which thereby extends the known range of this genus significantly. To promote consistency in generic recognition, we propose the transfer of Oploptera simplicicollis (LeConte, 1878) New Combination from Strongylium for the species distributed across the southeastern United States. Species diagnoses are given, and generic boundaries are discussed along with the expected diversity of the Sonoran Desert region.

THE MICROBLADE INDUSTRY FROM SWAN POINT CULTURAL ZONE 4b: TECHNOLOGICAL AND CULTURAL IMPLICATIONS FROM THE EARLIEST HUMAN OCCUPATION IN ALASKA

Colonization Process

Swan Point in central Alaska contains the oldest recognized human occupation in Alaska (Cultural Zone 4b [CZ4b]), dating to circa 14,000 cal BP. This component consists of a microblade and burin industry with clear technological ties to the Siberian Upper Paleolithic Diuktai Culture. Through the systematic use of the Yubetsu method for the production of microblades, Swan Point is technologically more similar to Siberian microblade sites than to later-age (Denali complex) microblade sites in Alaska. The Yubetsu method is the hallmark of the Diuktai Culture, and in Alaska, Swan Point CZ4b is the only component with systematic production of microblades using the Yubetsu method. Other late Pleistocene and Holocene microblade sites in Alaska have an industry based on Campus-style, conical, or tabular microblade cores. Analysis of the collection furthers our understanding of how CZ4b relates to previous Siberian Diuktai-related assemblages and to later Alaskan Denali-related sites. We interpret the CZ4b component as representing a brief single event that has major cultural and technological implications for the early colonization process of North America.

Artifact Type

AbstractGravel quarrying operations in 1962 at the well-known Clovis site north of Portales in eastern New Mexico uncovered important new evidence of Early Man. In February, a total of 17 punched blades was found after being mechanically exhumed and, on the basis of inferential evidence, these blades are assigned to the Llano complex that dates back some 11,000 to 13,000 years. The term “Clovis blade” is proposed for this new artifact type, which is discussed in detail. These implements, and the recent discovery of several blade-tools associated with the remains of four mammoths now being excavated by the El Llano Archaeological Society, lead to the postulation of a blade industry for the Llano complex; and evidence which indicates the persistence of the punched-blade technique up through Agate Basin times is presented.On the basis of technology, distribution, and apparent similarities to Upper Paleolithic blade cultures of the Old World, the classic Paleo-Indian cultures characterized by fluted points are believed to represent a unique, late Pleistocene migration that is temporally, culturally, and spatially distinct from the extremely early cultures of the Pacific coastal regions.

Drosophila suzukii (Diptera, Drosophilidae) is an exotic species, endemic to Asia and currently a pest to small and stone fruits in several countries of North America and Europe. It was detected in 2013 for the first time in South America, in the south of Brazil. Unlike most drosophilids, this species deserves special attention, because the females are capable of oviposit inside healthy fruits, rendering their sale and export prohibited. Despite the confirmed existence of this species in different states of Brazil, this insect is yet been to be given the pest status. Nevertheless, the mere presence of this species is enough to cause concern to producers of small fruits and to justify further investigation for it’s control, especially chemical control for a possible change in status. Therefore, the goal of this work was to evaluate, in laboratory, mortality of D. suzukii adults and ovicidal effect when exposed to different insecticides registered for species of the Tephritidae and Agromyzidae families in different cultures. The insecticides deltamethrin, dimethoate, spinosad, fenitrothion, phosmet, malathion, methidathion, and zeta-cypermethrin resulted in mortality to 100 % of the subjects three days after the treatment (DAT). Regarding the effects over eggs, it was  established that the insecticides fenitrothion, malathion, and methidathion deemed 100 % of the eggs not viable, followed by phosmet and diflubenzuron, which also caused elevated reduction in the eclosion of larvae two DAT.
