The exceptionally rich vertebrate locality of Ahl al Oughlam near Casablanca (Morocco) yielded abundant remains of Lagomorpha, composed of cranial and postcranial bones and many isolated teeth. They represent a new species of Prolagidae, Prolagus migrans n. sp., and two new Leporidae, Trischizolagus meridionalis n. sp. and Afrolagus pomeli n. g., n. sp. The main characters of the new Prolagus species are the large and anteriorly curved mesial hyperloph on P2, the lack of crochet, and the protoconulid isolated in most p3s.Trischizolagus meridionalis n. sp. is smaller than the common European species T. dumitrescuae, and differs in having in most p3 a massive outlined trigonid, mesofossetid and paraflexid. The second leporid Afrolagus pomeli n. g., n. sp. displays a unique p3 pattern not seen in the Old World leporids with the hypoflexid penetrating more than two thirds of the total width; it is probably formed by the fusion of hypoflexid and mesofosssetid, but leaves a wide lingual connection between the trigonid and talonid. Its upper molariform teeth have strongly wrinkled enamel along the edges of the hypoflexus. Despite these differences, it also shares several dental features with both the African genus Serengetilagus and the European genus Oryctolagus, to which it is compared. Prolagus and Trichizolagus are both well-known European genera. Their occurrence in the Plio-Pleistocene of Morocco is certainly due to a dispersal event thanks to terrestrial connection between the Iberian Peninsula and the Moghreb. In the light of recent faunal, biogeographic and chronological data, the beginning of mammalian exchanges in both directions dates from about 6.2 Ma. The locality of Ahl al Oughlam, although much younger, with an age estimated to 3.0-2.5 Ma, retains taxa resulting from this dispersal event, including the lagomorphs described here.

“…The Lower-Middle Pleistocene transition is well illustrated in Thomas I Quarry (Figure 2) where the oldest lithic assemblages of the Casablanca sequence are found in late Lower Pleistocene deposits, circa 1 Myr in Unit L on an excavation surface of about 1000 m 2 , and consist of Acheulian artifacts made on quartzite and flint [19]. In the same quarry, the archaeological assemblage of Unit 4 of the Hominid Cave, where hominid fossils were first brought to light in 1994, documents the Middle Pleistocene record.…”

The Mio-Plio-Pleistocene sequence at Casablanca, covering the last six million years, is well known in scientific literature. The variability and the chronology of the Acheulian sequence is documented by systematic, modern and controlled investigations in various sites (Unit L and Hominid Cave at Thomas I Quarry, Rhinoceros Cave at Oulad Hamida 1 Quarry, Sidi Abderrahman Extension Quarry, Bear's Cave and Cap Chatelier at Sidi Abderrahman Quarry) which have taken place within the framework of the Franco-Moroccan co-operative project "Casablanca". In order to manage the excavation data and to explore the taphonomic nature of Unit L, Hominid Cave and Rhinoceros Cave, where research is still in progress, an approach combining a Geographic Information System (GIS) and spatial analysis techniques was developed, incorporating all existing information produced from previous excavations and recent surveys of the sites. The amalgamation of this data into a GIS has resulted in a digital database that allows the production of simultaneous or separate visualizations and analyses of the fossils, artifacts and geological materials within their original spatial contexts and also permits intra-site spatial analyses that allow a comprehensive investigation of the site formation processes.

“…Several scenarios may be envisaged, for example either (i) rapid and ancient dispersal throughout western Europe of one (or several) new hominins, (ii) separate dispersals of new technical habits through a Levantine corridor or across the Gibraltar Strait from Morocco (cf. Bridgland et al ., ), where the earliest Acheulean assemblages around Casablanca have been dated by magnetostratigraphy to the latest part of the Matuyama chron (∼850 ka, or Marine Isotope Stage (MIS) 21: Raynal and Texier, ; Raynal et al ., , ), or (iii) a local origination in some areas due to an increase in skills of established populations.…”
