A fossil sea urchin from the Celtic site Goincet in the Forez (Poncins, dép. Loire) and a perspective at the meaning of ovum anguinum
Dieser Artikel behandelt die neue Entdeckung eines versteinerten Seeigels in einem archäologischen Fundkontext. Das Exemplar weist die notwendigen Charakteristika auf, um seine Art und seine vermutete Herkunft genauer bestimmen zu können. Der fossile Seeigel wurde wahrscheinlich aus einer Entfernung von mehreren Hundert Kilometern herbeigebracht. Es wird auch sein archäologischer Kontext untersucht, der sich im Bereich einer Straße in einer protourbanen Besiedlung befindet. Die archäologische Schicht mit dem Seeigel wird an das Ende des 1. Jahrhunderts v. Chr. datiert. Weiterhin wurde eine forschungsgeschichtliche Bilanz der Funde von versteinerten Seeigeln in ihrem vorkeltischen, keltische…
Position of the palaeontological site Aven I des Abîmes de La Fage, at Noailles (Corrèze, France), in the European Pleistocene chronology
Mourer-Chauvire, C., Philippe, M., Quinif, Y., Chaline, J., Debard, E., Guerin, C. & Hugueney, M. 2003 (September): Position of the palaeontological site Aven I des Abimes de La Fage, at Noailles (Correze, France), in the European Pleistocene chronology. Boreas, Vol. 32, pp. 521–531. Oslo. ISSN 0300–9483. The palaeontological locality of Aven I des Abimes de La Fage, at Noailles, Correze, France, is a limestone swallow hole filling which includes a rich fauna of micro- and macromammals, and one of the most complete Pleistocene avifaunas in the Palearctic. According to the mammal fauna and to the sedimentological study, the filling was previously assigned to the penultimate, Saalian, glaciat…
Ancient DNA evidence for the loss of a highly divergent brown bear clade during historical times
The genetic diversity of present-day brown bears (Ursus arctos) has been extensively studied over the years and appears to be geographically structured into five main clades. The question of the past diversity of the species has been recently addressed by ancient DNA studies that concluded to a relative genetic stability over the last 35,000 years. However, the post-last glacial maximum genetic diversity of the species still remains poorly documented, notably in the Old World. Here, we analyse Atlas brown bears, which became extinct during the Holocene period. A divergent brown bear mitochondrial DNA lineage not present in any of the previously studied modern or ancient bear samples was unc…
