This study is based on the anal y sis of the sedimentology and the fos sil as sem blages of Pleis to cene de pos its in East ern Tu nisia. It uses dif fer ent fauna as sem blages to help in fer palaeoenvironments and in par tic u lar dis cusses the im por tance of the dis tri bu tion of Persististrombus latus, es pe cially as re gards MIS 5e de pos its around the Med i ter ra nean Ba sin. The stratigraphic suc ces sion has been di vided into two main units. The lower unit is quartz-rich. Its basal part con tains a ma rine fauna that in cludes well-pre served bi valves, gas tro pods, echinoids and cirripedes dom i nated by Acanthocardia, Cerastoderma, Parvicardium, Arca, Donax, Glycymeris, Loripes, Tellina and Cerithium. This fauna rep re sents a typ i cal as so ci ation/biocenosis typ i cally de vel oped in a shel tered bay, of mod er ate to low wave/cur rent ac tion and rapid post-mor tem burial. The up per unit is car bon ate-dom i nated. Its basal part also con tains a rich ma rine fauna that in cludes the ex tant trop i cal West Af ri can spe cies Persististrombus latus. The oc cur rence of Persististrombus latus in this unit com pared to its pres ence in the whole Med i ter ra nean ba sin in the Late Pleis to cene leads us to ques tion its im por tance in the in ter pre ta tion of cli mate warming dur ing the Late Pleis to cene, and to sug gest its At lan tic or i gin.Key words: MIS 5 and MIS 7, Tu ni sia, malacofauna, palaeo ec ol ogy, Persististrombus latus, palaeoclimate.

Sedimentology and palaeoenvironmental reconstruction of the late Pleistocene deposits along the Bizerte Coast, N-E Tunisia

The N–E Tunisian coast (Bizerte region) shows several Quaternary sedimentary archives of middle to late Pleistocene age. Sedimentological analyses carried out (grain size, morphoscopy, exoscopy, petrography, mineralogy, and fossil content) on 12 sections reveal a succession that begins with infratidal deposits attributed to the last Interglacial period, followed by intertidal, continental (palaeosol) and/or aeolian deposits (aeolianites). The arrangement of these deposits, their lithological characteristics and their faunal contents are the basis for a palaeoenvironment reconstruction and estimation of palaeoclimatic conditions. A warmer climate and a high sea level characterize the beginning of this interval, followed by a sea level fall accompanied by an alternation of humid and arid climate. This alternation is reflected by intercalations of the palaeosol levels between the aeolian deposits.
