The elephant brain is famous for its higher than average encephalization quotient, memory capacities, large cerebellum, large facial and trigeminal nerves, and the extensive repertoire of complex behaviors and social interactions it produces, the last of which being supported by infrasonic communication. The evolutionary history of Proboscidea is a...
Article
Africa has played a pivotal role in the evolution of early proboscideans (elephants and their extinct relatives), yet vast temporal and geographical zones remain uncharted on the continent. A long hiatus encompassing most of the Eocene (Ypresian to the Early Priabonian, around 13 Myr timespan) considerably hampers our understanding of the early evo...

We provide detailed morphological description, including enamel microstructure, of the earliest known embrithopod mammals (Afrotheria, Paenungulata), Stylolophus minor and S. major, n. sp., recently discovered in the early Eocene of the Ouled Abdoun phosphate basin, Morocco. Stylolophus minor and S. major, n. sp., show close morphological affinity,...
Article
Early Pliocene hominin evolutionary scenarios proposed to date mostly rely on paleontological investigations from eastern Africa. Filling major geographical gaps in the fossil record could potentially invalidate these scenarios and stimulate development of improved theories. Based on published literature, no Pliocene fossil of continental vertebrat...
Article
The Oligocene Malembo locality, Cabinda exclave, Angola, has yielded a rich vertebrate fauna represented by fragmentary remains. This fossiliferous locality is the only definite occurrence of Oligocene terrestrial mammals in sub-Saharan West Africa. The hyracoids from Malembo have only been very succinctly described and compared thus far, so that t...
Article
A new fauna has been collected from a fissure filling named Cos in the Quercy region, southwestern France. It includes four primate species and a plesiadapiform. The cercamoniine adapiform Protoadapis andrei Godinot and Vidalenc, nov. sp., is represented by material that adds to our knowledge of the genus Protoadapis for the upper canine, upper mol...
Article
The Lophiodontidae are endemic perissodactyls from Europe that flourished during the Eocene. Despite their preponderance in the European fossil record, their exact origin and relationships within the perissodactyls remain unknown due to the rare and fragmentary material in the early Ypresian, the time of their earliest radiation. Lophiaspis maurett...

Résumé Dans la partie sud-est des Monts des Ksour (Algérie), une étude stratigraphique, paléontologique et sédimentologique a été effectuée sur les couches rouges qui affleurent sur la rive gauche de l’Oued Tafarahit. Il s’agit d’une série continentale détritique granodécroissante composée de microconglomérats, de grès et d’argiles attribuées au Cé...
Article
Understanding the origins of morphological specializations in mammals is a key goal in evolutionary biology. It can be accomplished by studying dental homology, which is at the core of most evolutionary and developmental studies. Here, we focused on the evolution and development of the specialized dentition of hyraxes for which dental homologies ha...
Article
We report here three new elasmobranch fossil taxa from Thanetian–Lower Lutetian nearshore marine deposits of northeastern (Matam region) and central-western (Sine-Saloum region) Senegal. These three new taxa represent the oldest species of the enigmatical elasmobranch Odontorhytis, the oldest putative representatives of marine potamotrygonid, and a...
Article
The upper Cretaceous of the eastern part of the Ksour Mountains (Western Saharan Atlas, Algeria) is classically subdivided into three fossiliferous lithostratigraphic formations: El Rhelida (lower Cenomanian), Mdaouer (lower-middle Cenomanian) and Rhoundjaïa (upper Cenomanian-lower Turonian). The western part of the Ksour Mountains, which is less d...

Bulk sampling of an indurated glauconic sandstone horizon from Djebel el Kébar, Central Tunisia, yielded a moderately diversified assemblage of elasmobranchs (sharks and rays), dating from the late Middle Eocene (mid Bartonian). Here, 10 new taxa (nine new species and three new genera) are described among a total diversity of 33 species. These new...
Article
A long hiatus encompassing most of the Eocene (end of the Ypresian to the early Priabonian) breaks up the proboscidean evolutionary history, which is otherwise documented by a rich fossil record. Only two post-Ypresian localities from West Africa (Mali and Senegal) have yielded scarce Moeritherium -like dental remains. Here, we study one of these r...
Article
Full-text available
Seven hystricognaths and five anomaluroids have been recently described from the earliest Oligocene of the Dakhla (DAK C2) region of Morocco, based primarily on isolated cheek teeth. Here, we analyzed the enamel microstructure of thirty associated isolated fragments of incisors. Among these specimens, only three display an early stage of uniserial...
Article
Cetaceans constitute a textbook example of the secondary adaptation of tetrapods to aquatic life. This major event in the evolutionary history of mammals is often linked in the literature to the limb‐to‐fin transition. Paradoxically, limb bones are scarce in the fossil record of early cetaceans, and the transition from a limb‐adapted morphology for...

La découverte dans les années 1960 d’un gisement fossilifère à vertébrés dans les calcaires lacustres autour d’Aumelas (ouest de Montpellier) fut l’une des premières mentions de mammifères dans l’Eocène moyen du sud de la France. Rapproché du niveau repère mammalien paléogène MP13 (fin Lutétien), le gisement d’Aumelas constituait alors un jalon dét...
Article
Anthracotheres dispersed from Asia toward Africa at least three times: at the Eocene/Oligocene transition, during the early Miocene and later during the Miocene. Those dispersals are important datum events for African Tertiary biochronology. New fossil remains of early Libycosaurus, the genus implicated in the late Miocene dispersal, are described...
Article
The Lophiodontidae is an emblematic and well-documented Eocene family of perissodactyls from Western Europe. However, after more than a century and a half of studies, lophiodontids still display a complex systematics associated with blurry intraspecific variation and a poorly known early radiation. The locality of La Borie, located near the city of...
Article
New Palaeogene vertebrate localities were recently reported in the southern Dakhla area (southwestern Morocco). The Eocene sediment strata crops out on cliffs along the Atlantic Ocean coast. Vertebrate remains come from five conglomeratic sandstone beds and are principally represented by isolated teeth belonging to micromammals, selachians and bony...
Article
A post-Priabonian fluviatile debris-flows in Mabrouk (MBK), Djebel Chambi – Tunisia, have yielded a surprisingly rich assemblage of reworked marine elasmobranchs (23 taxa of sharks and rays). By comparison with their sub-coeval counterparts from northeastern Africa, this assemblage suggests an age ranging from the latest Priabonian up to the earlie...

This contribution contains the 3D models of the fossil remains (maxilla, dentary, and talus) attributed to Djebelemur martinezi, a ca. 50 Ma primate from Tunisia (Djebel Chambi), described and figured in the following publication: Marivaux et al. (2013), Djebelemur, a tiny pre-tooth-combed primate from the Eocene of Tunisia: a glimpse into the orig...
Presentation
The Hyracoidea was a successful mammalian order in Africa from the early Eocene to the mid-Miocene. Through the Eocene/Oligocene, hyracoids represented the dominant 'ungulate' group in terrestrial ecosystems. Among them, the genus Titanohyrax embraces very large species as well as a small one, T. tantulus, only known from the ?early/middle Eocene o...
Article
Diacodexeidae are the first representatives of Artiodactyla in the fossil record. Their first occurrence is at the very base of the Ypresian (earliest Eocene, 56.0 Ma) with Diacodexis, a genus well diversified during the early Eocene in Europe, especially during the MP7–MP8 + 9 interval. However, most of European species are documented by scarce ma...
Article
Hypolophin ‘dasyatids’ are a common group of large stingrays today frequenting the Indo-Pacific inshores. Being often harvested in their restricted area, few are known about their biology and their evolutionary history despite a very peculiar dental pattern making it easy to track their fossil record. An abundant material consisting of isolated tee...

We investigated dental homologies, development, and growth in living and fossil hyracoids and tested if hyracoids and other mammals show correlations between eruption patterns, gestation time, and age at maturity. Unlike living species, fossil hyracoids simultaneously possess replaced P1 and canine teeth. Fossil species also have shorter crowns, an...
Article
The age of the Paleogene deposits of the Haut Var (Provence, France) has been the subject of debate. Particularly, the ‘Calcaire à Bithynies’ and the ‘Sables bleutés’ units were ascribed either to the early Eocene or to the Oligocene. A stratigraphical clarification is required in order to precise the paleogeographical relationships of the Haut Var...
Article
Recent palaeontological field campaigns in the westernmost part of the Sahara (Dakhla region, Morocco) have resulted in the discovery of a mammal assemblage including anomaluroid rodents. This new fauna comes from the uppermost part of the Samlat Formation, which contains estuarine deposits dating from the earliest Oligocene. The anomaluroid record...

Living representatives of the mammalian order Hyracoidea are poorly diversified with only three small-sized genera restricted to Africa and Middle East. Conversely, during the Paleogene, several extinct hyracoid families represented the dominant ‘ungulate’ group in African terrestrial ecosystems. Among them, the Titanohyracidae embraced ten extinct...

The porcupines, cane-, mole- and dassie-rats are the modern representatives of the African hystricognathous rodents. Although these rodents are among the most common members of African mammal faunas from the Mid-Paleogene (late middle Eocene – early Oligocene interval), their early record has so far remained limited to North and Northeast Africa. W...

Terrestrial gastropods occur in many North African localities in Eocene continental deposits. Here we analyse the faunal assemblage from the Hamada de Méridja Formation in southwestern Algeria, dated as Early to Middle Eocene on the basis of charophytes. The assemblage consists of three closely related species that to date have been classified eith...
Article
Chambius kasserinensis from the late Early or early Middle Eocene Chambi locality, central Tunisia, is undoubtedly the oldest known macroscelidid and possibly the basalmost representative of the order Macroscelidea. Hence, since its discovery in 1986, Chambius has played a key role in analyses focusing on afrotherian and eutherian phylogeny; for in...

Among medium- to large-sized terrestrial ‘ungulates,’ there is often a relationship between increasing body size, correlated changes in diet, and increased complexity of the enamel microstructures [notably the development of Hunter-Schreger bands (HSB)]. An exhaustive survey of the enamel microstructures of living and extinct Hyracoidea demonstrate...
Article
We present and describe new fossils from the Eocene North African localities of Chambi (Tunisia; late Ypresian or early Lutetian) and Bir el Ater (Algeria; latest Bartonian or earliest Priabonian). The specimens from Chambi allow recognizing two recently described hyainailourines: Furodon crocheti and Parvavorodon gheerbranti; these taxa were previ...

The Kasserine area, in central Tunisia, is for a long time considered by many authors as an emerged island (or islets), since the upper Cretaceous until the middle Miocene. In the eighties, continental deposits were described and dated Eocene. At that time, no marine deposit older than middle Miocene were thus known in central Tunisia, and the only...

Seggeurius is the basal-most hyracoid known to date, and one of the earliest known fossil afrotherians. This taxon has a dramatic importance in mammalian phylogeny, but until now it was known from dental remains only. Here we describe previously unpublished material of Seggeurius, including some mandibular and maxillary fragments, and a braincase....

Among the Afro-Arabian Palaeogene chiropterans, philisids were the most common and diversified members. The Philisidae are considered as an extinct primitive group of Vespertilionoidea, a well-diversified superfamily that today includes Natalidae, Molossidae and Vespertilionidae. However, the position of Philisidae within this superfamily has never...
