Abstract

The Musalà section, south-east of Villa S. Giovanni (Calabria, Italy), shows a sequence of sand and gravel deposita, their source area being the emerged metaniorphic substratum.
The section exhibits two basal levels, poorly fossiliferous and characterized by several sedimentary structures such as «grain flow» and «cross bedding». These deposits are followed by a level of coarse-grained sands rich in fossils and lacking in sedimentary structures. The top of the sequence showing a low content of fossils, consists of fine sands, grading up to gravels and overlying coarse-grained sands.
The palaeoecologic study of the intermediate fossiliferous level, mainly concerning Molluscan and Bryozoan faunes, allows a palaeoenvironmental reconstruction. The observed association has been referred to an in situ palaeocommunity which can be related to the modem Biocoenosis (SGCF) mixed with several other species suggesting different habitats and ages. In fact, in this level species which are characteristic of Infralittoral and/or Circalittoral biocoenosis surroundings toghether with species of deeper habitats from coeval levels, and a last stock of species reworked from older strata are present.
The sands of Musalà can be related to the latest Lower Pleistocene, because of the presence of «boreal guests» such as Buccinuin undatum, Spisula elliptica, Chlamys septemradiata and Tapes rhomboides, This is, also, confirmed by the size increase of some species such as Timoclea ovata.
