“…Deposits associated with the older of these two events [Unit I] consist of a series of red sandstones and mudstones considered to be Cretaceous in age, based in part on faunal and lithological similarities with Aptian Dinosaur Beds of Malawi (Dixey, 1928;Spence, 1954;Colin and Jacobs, 1990;Jacobs et al, 1990;Mateer et al, 1992). These deposits are dominated by medium grained, dark red (5R 2/6) to grayish purple (5P 4/2) sandstone with occasional basal pebble conglomerate and thin, lenticular dark red (5R 2/6) mudstone and siltstone.…”

“…The most glaring geographic deficiency in this emerging story remains sub-equatorial Africa. Non-marine Cretaceous strata in sub-equatorial Africa are extremely rare and low in vertebrate diversity (Dingle et al, 1983;Mateer et al, 1992), with two notable exceptions: the Berriasian-Valanginian Kirkwood Formation of South Africa (Broom, 1904;Galton and Coombs, 1981;Rich et al, 1983;Ross et al, 1999;de Klerk et al, 2000), and the Aptian Dinosaur Beds of Malawi (Dixey, 1928;Haughton, 1928;Colin and Jacobs, 1990;Jacobs, 1990;Jacobs et al, 1990Jacobs et al, , 1992Jacobs et al, , 1993Gomani, 1999).…”

“…They gave the age as late Coniacian-Santonian (Upper Cretaceous). Moody and Sutcliffe [1991] and Mateer et al [1992] indicated that the In Beceten Formation extends from the uppermost Coniacian (86.3-89.8 MY) through almost all the Santonian (83.6-86.3 MY). We set the range as 83.6-88.0 MY, truncating the lower part of the Coniacian.…”

Published data from DNA sequences, morphology of 11 extant and 15 extinct frog taxa, and stratigraphic ranges of fossils were integrated to open a window into the deep-time evolution of Xenopus. The ages and morphological characters of fossils were used as independent datasets to calibrate a chronogram. We found that DNA sequences, either alone or in combination with morphological data and fossils, tended to support a close relationship between Xenopus and Hymenochirus, although in some analyses this topology was not significantly better than the Pipa + Hymenochirus topology. Analyses that excluded DNA data found strong support for the Pipa + Hymenochirus tree. The criterion for selecting the maximum age of the calibration prior influenced the age estimates, and our age estimates of early divergences in the tree of frogs are substantially younger than those of published studies. Node-dating and tip-dating calibrations, either alone or in combination, yielded older dates for nodes than did a root calibration alone. Our estimates of divergence times indicate that overwater dispersal, rather than vicariance due to the splitting of Africa and South America, may explain the presence of Xenopus in Africa and its closest fossil relatives in South America.

“…Those basins (namely, the Taoudeni, South Algerian, Murzuq, Chad, and Iullemmeden basins) developed either on Neoproterozoic-Paleozoic platform sequences or directly on the basements (Radier, 1959;Greigert, 1966;Busson and Cornée, 1991;Fabre et al, 1996;David son et al, 2000). Jurassic and mostly Lower Cretaceous intracratonic sediments have been grouped as the "Continental Intercalaire" (e.g., Dars, 1960;Lefranc, 1983;Lefranc and Guiraud, 1990;Mateer et al, 1992;Fig. 2).…”

The geological evolution of northwestern Africa and its continental margins is investigated in the light of nine Meso-Cenozoic paleogeological maps, which integrate original minimal extent of sedimentary deposits beyond their present-day erosional limits. Mapping is based on a compilation of published original data on the stratigraphy and depositional environments of sediments, structures, magmatism, and low-temperature thermochonology, as well as on the interpretation of industrial seismic and borehole data.We show that rifting of the equatorial domain propagated eastward from the Central Atlantic between the Valanginian (ca. 140 Ma) and the Aptian (ca. 112 Ma) as an en echelon strike-slip and rift system connected to an inland rift network. This network defines a six-microplate synrift kinematic model for the African continental domain. We document persistent, long-wavelength eroding marginal upwarps that supplied clastic sediments to the offshore margin basins and a large intracratonic basin. The latter acted as a transient sediment reservoir because the products of its erosion were transferred both to the Tethys (to the north) and the Atlantic Ocean. This paired marginal upwarpintra cratonic basin source-to-sink system was perturbed by the growth of the late Paleogene Hoggar hotspot swell that fragmented the intracratonic basins into five residual depocenters. By linking the evolution of the continental margins to that of their African hinterland, this study bears important implications for the interplay of long-wavelength deformation and sediment transfers over paired shield-continental margin systems.
