“…Paleogene marine sediments have been studied mostly in the Benguela Basin and in Cabinda. Adnet et al (2009) recognized a new species of Eocene lamniform shark, Xiphodolamia serrata, from Benguela. Sharks and bony fishes from Cabinda have been listed by Solé et al (2018), and Taverne (2016) has provided new information about osteoglossid fishes from Lândana.…”

This chapter provides an overview of the alpha paleobiodiversity of Angola based on the available fossil record that is limited to the sedimentary rocks, ranging in age from Precambrian to the present. The geological period with the highest paleobiodiversity in the Angolan fossil record is the Cretaceous, with more than 80% of the total known fossil taxa, especially marine molluscs, including ammonites as a majority among them. The vertebrates represent about 15% of the known fauna and about one tenth of them are species firstly described based on specimens from Angola.

A Middle–Late Eocene vertebrate fauna (marine fish and mammals) from southwestern Morocco; preliminary report: age and palaeobiogeographical implications

2010

Recent field work in the southern Moroccan Sahara (‘Western Sahara’), south of the city of ad-Dakhla, has led to the discovery of several new fossiliferous sites with fossil vertebrates in sedimentary deposits previously reported for the Mio-Pliocene. The sedimentology and geological setting of the studied area are briefly reported here, and at least three units have been identified in successive stratigraphical sequences according to their fossil content. The first preliminary list of vertebrate associations is reported and consists mainly of isolated teeth belonging to selachian and bony fishes, a proboscidean tooth currently assigned to ?Numidotherium sp. and many remains of archaeocete whales (Basilosauridae). At least 48 species of selachians are presently identified; many of them are new and others are recorded in the late Middle Eocene (Bartonian) and Late Eocene (Priabonian) of Wadi Al-Hitan (Egypt) or Wadi Esh-Shallala Formation (Jordan) as in other African localities (e.g. Otodus cf. sokolowi, ‘Cretolamna’ twiggsensis, Xiphodolamia serrata, Misrichthys stromeri, Hemipristis curvatus, Galeocerdo cf. eaglesomi, Propristis schweinfurthi), probably indicating a Late Eocene age for unit 2 of the bedrock successions. The evolutionary trend noticeable on the proboscidean tooth is in agreement with such an assumption, by comparison with the close relative species known from the Eocene of Egypt, Libya and Algeria. Indeed, the faunal associations from the Dakhla area clearly demonstrate the erroneous age of these deposits, previously thought to be Mio-Pliocene. It suggests a correlation in age (late Middle Eocene–Late Eocene) and a similar environment with the famous marine deposits from Egypt and Jordan. It opens new opportunities to understand the biogeography and the surprising similarity of landscape between West and Northeast Africa during the Bartonian–Priabonian period.

Large‐Scale Tectonic Forcing of the African Landscape

We investigate how large-scale tectonic forcing can influence landscape development. The combined forward and inverse modeling strategy that we exploit is known as closed-loop modeling or twin experimentation (Canet et al., 2009;Li et al., 2011;Lorenz, 1963). This approach is often employed by the seismological community and is a helpful means for objectively investigating complex systems that is based upon a combination of guided forward and inverse modeling. Here, we adopt a three-fold strategy. First, we extract a regional uplift history by inverting a revised and augmented inventory of river profiles. This approach builds upon previous work by Paul et al. (2014), Wilson et al. (2014), and Rudge et al. (2015. The recovered history is independently calibrated, and then separately tested (i.e., validated) using two different suites of geologic observations. Second, the recovered uplift history is used to force a series of dynamic landscape simulations for a sequence of increasingly complex spatio-temporal precipitation patterns. Finally, synthetic river profiles extracted from these simulated landscapes are inverted in order to gauge recoverability of the original regional uplift history. It is important to emphasize that the source of the original uplift history is not relevant-the principal issue concerns recoverability of any
