“…Habib and Drugg (1983) considered the last occurrence of B. johnewingii in the Himantoceras trinodosum ammonite subzone. In Moroccan sec tions, the first occurrence of C. elegantulum is within the up permost Valanginian (Below, 1982a). Therefore, the basal range of this species is known from the Berriasian (Habib and Drugg, 1983;Williams and Bujak, 1985).…”

“…D. cerviculum has a sporadic first strati graphic occurrence in the lower Valanginian (Jardine et al, 1984;Monteil, 1985) and a persistent occurrence in the upper Valanginian (Jardine et al, 1984). D. cerviculum has been ob served within the lowermost Valanginian in well-dated sections of Morocco (Below, 1982a). For the Tethyian realm, Williams and Bujak (1985) considered the first occurrence of D. cerviculum as late early Valanginian.…”

The dinoflagellate cyst assemblages in 42 samples collected from Sites 638 and 639 were analyzed. All samples from Site 639 are barren; relatively poor assemblages occur in samples from Site 638. The distribution of 61 dinoflagellate cyst taxa identified in samples from Holes 638B and 638C are tabulated.The assemblages from Site 638 are comparable to those of Tethyian stratotypes and from neighboring areas, which permits age determinations and correlations between Holes 638B and 638C. The interval from Cores 103-638C-14R to 103-638C-1R is late Berriasian through Valanginian in age. In Hole 638B, the interval from Core 103-638B-43R to Sec tion 103-638B-23R-2 is dated as early Valanginian through middle Barremian. Sections 103-638B-21R-2 and 103-638B-21R-1 are late Aptian in age.Taxonomic remarks are made about some species; a new dinoflagellate cyst Heterosphaeridiuml galiciae is de scribed.

The paper describes the palynology, stratigraphy, sedimentology and palaeogeographic setting of Lower Cretaceous turbiditic and terrigenous deep-sea sediments at the Tethyan margins of Africa and Alboran (External Domain of the Rif, and Flysch Nappes). During the Early Cretaceous terrigenous turbiditic deep-water sedimentation characterizes two different palaeogeographic domains in the southern part of the western Tethys: In the northern area of the External Domain (Ketama Unit of the Rif) alternating turbiditic arenites and pelites are interpreted as sediments of a distal part of a fan system on the Tethyan margin of Africa. The main sources for the terrigenous material were situated in Central and Western Algeria; only little sand transited through the Prerif and the Mesorif zones of Morocco. The terrigenous sedimentation began in the Hauterivian, but the main turbiditic cycles are of Aptian to Lower and Middle Albian age. The Flysch Domain probably was situated far to the Northeast with respect to the Rif basin, at the western and southern margins of the Alboran microplate. Relatively proximal turbidites form most of the Tisirène Nappe, whereas more distal turbidites constitute the series of the Melloussa and the Chouamat Nappes. The existence of two different source areas is demonstrated, one to the NE and the other to the NW of the depositional area. The turbidites probably were deposited on a E-W oriented fan system which progradated into a longitudinal trench-like trough. In the Central Rif area, the Tisirène Flysch is of Valanginian to Albian (pre-Vraconian) age. In the Western Rif and in the Melloussa and Chouamat Nappes of the whole area no sediments older than Aptian have been found. The stratigraphy of the investigated series is based on a new tentative palynostratigraphic zonation, using pollen, spores and dinoflagellate cysts. Rich and well preserved assemblages have been found in the Western Rif only, whereas the samples of the Tisirène Nappe and the Chouamat Nappe in the Central and Eastern Rif have been affected by some thermal alteration. Black and mostly opaque palynomorphs from the Ketama Unit reflect the strong thermal influence in the External Domain of the Central and Eastern Rif
