Forecasting land use and land cover dynamics using combined remote sensing, machine learning algorithm and local perception in the Agoènyivé Plateau, Togo
2023, Remote Sensing Applications: Society and EnvironmentNew data on the Dyrosauridae (Crocodylomorpha) from the Paleocene of Togo
2021, Annales de PaleontologieCitation Excerpt :The Togolese specimens come from the base of the limestone level, contacting the detrital basal unit (boundary between oxidized sands and the limestone). These limestones were deposited in a shallow marine environment or a lagoon (coastal) containing a rich benthic fauna (Johnson et al., 2000; Da Costa, 2005). This abundance of benthic invertebrate specimens concurs with bioclast diversity (gastropods, bivalves, brachiopods) and the abundance of well-preserved oyster shells attached to some bone remains (Fig. 5C).
First partial cranium of Togocetus from Kpogamé (Togo) and the protocetid diversity in the Togolese phosphate basin
2021, Annales de PaleontologieCitation Excerpt :In the southwest, the most basal facies consists of greenish stratified clay overlain by a thin layer of greyish clay. In the northeast part of the quarry (Johnson, 1987; Cappetta and Traverse, 1988; Johnson et al., 2000), this clay is absent, and a bone bed occupies the same stratigraphic position (Johnson, 1987; Cappetta and Traverse, 1988; Johnson et al., 2000). On top of this clay layer, the main phosphate deposit is composed of alternating thick layers of soft brownish phospharenite (50 cm to 300 cm) and a thin layer of purplish compact oxidised phosphate (10 cm).
Elasmobranchs from the upper Paleocene of Togo
2020, GeobiosCitation Excerpt :Numerous bioturbations containing crustacean remains mark the limit between the glauconitic biomicrite and the glauconitic sandstone. The glauconitic biomicrite level yielded planktonic foraminifera that suggest an upper Paleocene age (Biozone P4; Da Costa et al., 2009, 2013c; Johnson et al., 2000), whereas previous biostratigraphic data provided contentious results for the glauconitic sandstone. Based on planktonic foraminifera, this level was assigned to the biozones P5-P6 (Da Costa et al., 2009, 2013d), whereas calcareous nannofossils indicate an age within the biozones NP9-10 (Da Costa et al., 2013b).
