Recherches de mammifères paléogènes dans les départements de l'Aisne et de la Marne pendant la deuxième moitié du vingtième siècle
Pierre Louis
Keywords: Biochronology; Eastern Paris Basin; Fossil localities; Mammals; paleoenvironments; Paleogene; Paleogeography
 
  Abstract

    A brief historical account of fossil vertebrate discoveries in the Eastern part of the Paris Basin between the beginning of the nineteenth century and 1950 is given. Other localities discovered since then are presented. A reconstruction of past landscapes is briefly elaborated. A biozonation based on mammals is proposed, from the Late Thanetian to the Middle Bartonian. Paleogeographical considerations are added. Suggestions regarding the search for new marnmal localities are made.

Essai de filiation des campagnols et des lemmings (Arvicolidae, Rodentia) en zone holartique d'après la morphologie dentaire.
Jean Chaline
Keywords: Arvicolidae; Dental morphology; Paleogeography; phyletic relationships
 
  Abstract

    The Arvicolid evolution results in an increase of the dental structure complexity. The M3/ differenciation seems to characterise the tribe subdivisions, that of M/1 being variable from one to another lineage. The phyletic relationships of fossil lineages are discussed from a paleogeographic point of view.
