This poster has been realized in collaboration with another poster (cf. this book : Fechner et al.) in order to examine both environmental and archaeological aspects of the so-called V-shaped pits (or Schlitzgrube) series of archaeological features. Here, research carried out in Champagne and Normandy show that it consists in a phenomenon covering not only a wide area of northern France but also of Central and Western Europe, and a long-time scale too from ancient Neolithic to Early Bronze Age. Case studies give the opportunity to detail their morphological variability, rhythm of use and environment within it was dug. Function is discussed for a century, mainly because artifact is missing. According to many recent environmental and archaeological data, the hypothesis of trap for wild herbivore has yet to be considered with close attention.
