During an archaeological career that spanned four decades, John Beach Rinaldo (1912-1999) made substantive contributions to the delineation and definition of the Mogollon Culture, the culture history of west-central New Mexico and east-central Arizona, and the identification of material relationships between precolumbian cultures and modern-day Zuni. For a variety of reasons, Rinaldo is overshadowed by his Field Museum collaborator Paul Sidney Martin. As a result, historians of archaeology have failed to critically evaluate Rinaldo's career and contributions. This paper offers a controlled analysis and comparison of data in unpublished archives, artifact collections at the Field Museum, and the published record to illuminate previously unrecognized but important aspects of Rinaldo's many contributions to archaeological knowledge, method, and theory.

A survey of private and public collections produced information on 410 fluted point yielding localities within a single county in east central Ohio. Analysis of techno-functional attributes of the fluted points resulted in the definition of four general settlement types including large and small workshop/occupations, chert processing loci, and food procurement/processing loci. The distribution of these loci in relation to various features of the local paleoenvironment suggests that Paleo-Indian bands were seasonally exploiting the diverse environments of the Appalachian Plateau. Subsistence activities appear to have focused primarily on dispersed, non-aggregated game species such as white-tailed deer. The dense concentration of fluted points here may simply reflect the high redundancy in the Paleo-Indian land use system in areas with limited loci of availability for critical chert resources.

Abstract. In the Lusitanian Basin (west-central Portugal), Upper Jurassic (Oxfordian) sediments were investigated in order to identify palaeontological assemblages of charophytes. Systematic studies were undertaken on specimens obtained from four field sections (Pedrógão, Vale de Ventos, Memória and Valverde). These studies revealed the presence of new forms of Porocharaceae (Porochara pedunculata n. sp) and of forms previously unknown in this region (Auerbachichara cf. saidakovskyi), as well as P. raskyae, P. minima, P. fusca, P. sulcata, P. kimmeridgensis, Aclistochara longiformis and Porochara sp. Comparison of the charophyte palaeofloras recognized in all of the studied sections has allowed the definition of three different assemblages which, coupled with other data, help to correlate these successions of Early (?) to Middle (Late?) Oxfordian age.

In order to discuss the origin of the Michelsberg culture, a question which has been the subject of much debate during the last five years, a closer definition of the culture is first necessary. This paper begins by reviewing the theories as to origins which have been offered during the last half century, a detailed description of the elements making up the various subdivisions of the culture is then attempted, together with some observations on the internal chronology of the material; and in conclusion a return is made to the question of origin.We owe to Schumacher the first identification of the culture by name, though it was Reinecke's contribution two years later which proposed its attachment to a ‘western’ neolithic family in an article written, as usual, with an insight years ahead of its time. Schumacher had thought that the culture was a late phase of Bandkeramik (Danubian I) influenced by Schnurkeramik (Corded Ware).Later, Reinecke modified his views somewhat and noted the close connection between the material of the Swiss lake dwelling cultures and the mesolithic of Scandinavia and, in two short papers, laid the basis for the second of the principal theories as to origins. It is interesting that the same man was responsible for two major trends in archaeological thought on the question.

Species of North American Cybaeus L. Koch (Araneae: Dictynoidea: Cybaeidae) are common moist-forest spiders classified in Holarctic and Californian clades. Here we review the adenes species group of the Californian clade. We recognize nine species: Cybaeus adenes Chamberlin & Ivie, C. amicus Chamberlin & Ivie, C. auburn Bennett spec. nov., C. grizzlyi Schenkel, C. pearcei Bennett spec. nov., C. reducens Chamberlin & Ivie, C. sanbruno Bennett, C. schusteri Bennett spec. nov., and C. torosus Bennett spec. nov. The species of the adenes group have extremely restricted ranges in west central California from Sonoma and Napa Counties south to northern Monterey County and in east central California from Placer and El Dorado Counties. Descriptions, illustrations, range maps, and an identification key are provided for all species.
