A new Late Ordovician microdomatid gastropod genus from Seville,south west Spain,with a revision of Ordovician Microdomatoidea

A new microdomatid gastropod, Eopagodea sevillana gen. and sp. nov., is described from the Late Ordovician (pre-Hirnantian Ashgill) limestones of Seville, Ossa Morena Zone, Spain. Palaeozoic microdomatids lived in shallow-water environments and were restricted to warm-water regions. Occurrence of microdomatid gastropods in the pre-Hirnantian Ashgill limestones of the Cerrón del Hornillo syncline (Ossa Morena Zone, Spain) is interpreted as an example of an influx of warm-water faunal elements into the otherwise cool to cold climate of the Mediterranean region during a short-termed, pre-Hirnantian increase of palaeotemperatures. The Late Ordovician microdomatid genus Daidia Wilson, 1951, is revised and two new Late Ordovician (Ashgill) subspecies of Daidia cerithioides (Salter, 1859) are described: Daidia cerithioides sewardensis n. subsp. from the Don River area of the York Mountains, Seward Peninsula, western Alaska, and Daidia cerithioides wilsonae n. subsp. from the Little East Lake Formation of northwestern Maine.     

Religion And Technological Innovation: The steamboat in 1840s France

Summary

Looking beyond the reaction to and the discourses surrounding inventions, it may appear incongruous to link religion with technological innovation, especially considering the underlying religious motivations of the inventive act. Steamship propulsion and the search for an alternative to the paddle wheel in 1840s France implicates three inventors (Frédéric Sauvage, Augustin Normand, Achille de Jouffroy d'Abbans) and three inventions (the continuous propeller, the divided propeller, the flipper apparatus); only Normand's propeller would have a vertiable future. This contest also entails three different types of religious temperaments: a Romantic religiosity, a “bourgeois” or private Catholicism; and a clerical‐legitimist militancy. The question which will be considered here is: were these inventors influenced by the strength of their religious convictions; and if so, how did this affect their scientific reasoning ?

The collapse of memory: The case of farm workers (French Vexin,pays de France)

The two authors have carried out an oral survey on a group of retired farm labourers in the French Vexin and the Pays de France regions (north of the lle de France). This paper examines the means by which individual memory registers the collective downward trend of this social group. It is remarkable for instance that respondents tend to recall memories of the “life of yore”;, opposed to life nowadays, instead of describing precise stages of their career, or the social evolution of their group and of the region. Their vision of History is fatalistic, syncretical, motionless, with frequent reference to war, exodus, moments of horror. All these elements express indirectly how a social group was crushed. Fragments of oral litterature that were collected on the same occasion refer also to the theme of social failure.     

Human occupation in South America by 20,000 BC: the Toca da Tira Peia site,Piauí, Brazil

When and how did the first human beings settle in the American continent? Numerous data, from archaeological researches as well as from palaeogenetics, anthropological and environmental studies, have led to partially contradictory interpretations in recent years, often because of the lack of a reliable chronological framework. The present study contributes to the establishment of such a framework using luminescence techniques to date a Brazilian archaeological site, the Toca da Tira Peia. It constitutes an exemplary case study: all our observations and measurements tend to prove the good integrity of the site and the anthropological nature of the artifacts and we are confident in the accuracy of the luminescence dating results. All these points underline the importance of the Toca da Tira Peia. The results bring new pieces of evidence of a human presence in the north-east of Brazil as early as 20,000 BC. The Toca da Tira Peia thus contributes to the rewriting of the history of the peopling of the American continent.
