In the present paper a revision of some taphonomic criteria commonly used in the interpretation of fossil mollusca assemblages is realized . The field work on living and death assemblages of mollusca in a shallow muddy bottom has been carried out in the coast near Denia (Alicante, Spain). Although the supposed lineal relation between specific abundance and probability of autochthony could explain the structure of part of the considered assemblages, in other a clear disagreement due to a massive incursion of youth elements in observed . By other hand, the possibility of horizontal transport not detectable by these means (anonymous alochtonic fluxes) imposes another limitation to the pretende…
