Marine crocodylomorphs were particularly abundant in Europe during the Middle Jurassic, but were very scarce in Africa. New finds of thalattosuchian cranial remains in Morocco suggest that this scarcity is probably related to poor sampling rather than original diversity. These remains pertain to the coastal thalattosuchians, the teleosauroids, and particularly to the clade grouping the blunt-toothed 'Steneosaurus' obtusidens and the genus Machimosaurus. A new tribe is erected grouping these two taxa: Machimosaurini. Until now the machimosaurins have been known from the middle Callovian. The new material extends the presence of this group further back to the lower Bathonian, nearly 5 myr earlier. The machimosaurins are the only teleosauroid group that has been recently reviewed, and the difference between the revised diversity provided herein and that previously reported is large. A review of other teleosauroids and clear establishment of their phylogenetic relationships are also likely to have considerable impact on their observed diversity. So, until a complete review of the teleosauroids is carried out, the results of crocodylomorph diversity analyses should be treated with caution.

“…M. Monbaron, J. Jenny, A. Le Marrec discovered several localities with dinosaur bones and tracks (Jenny et al 1981). Monbaron found in May 1978 some fossiliferous outcrops near Isseksi and collected the proximal part of a sauropod humerus (Monbaron 1978) and then the elements of a sauropod skeleton, which were lately collected by French archaeologists directed by Debenath et al (1979).…”

A century of prospecting and exploring in North Africa has led to the discovery of remarkable dinosaur localities and excavating spectacular and diverse faunas from the Mesozoic outcrops. The first observations and publications were the work of courageous travellers, intrepid naturalists or motivated soldiers. They were followed by scientific expeditions with the main purpose of collecting more complete remains of these fascinating fossil reptiles, the dinosaurs.Today, by the number, the variety and the importance of its dinosaur localities, the Maghreb has nothing to envy the paleontological richness of dinosaurs from North America or Asia. The description of new genera and new species of dinosaurs discovered recently in North Africa completely changed the vision we had of these Mesozoic reptiles, together with the knowledge of their history and geographical distribution. From the first discovery of dinosaur footprints in the south of Algeria in 1880 to the most recent collection of Liassic dinosaur bones in the High Atlas Mountains of Morocco, and with the exploration of the Cenomanian sediments of the Egyptian desert, numerous localities have yielded splendid and fascinating new theropods, sauropods and ornithopods. The countries of North Africa and especially of the Maghreb are now the first places among the most famous dinosaur localities in the world. Their faunas contributed greatly to understanding of the evolution of life during the Mesozoïc. Résumé: Un siècle de prospections et d'explorations a permis de découvrir en Afrique du Nord de remarquables gisements de Dinosaures et de mettre au jour des faunes spectaculaires et variées enfouies dans les sédiments du Mésozoïque. Les premières observations et publications furent l'oeuvre de voyageurs courageux, de naturalistes intrépides ou de militaires motivés. Ils furent suivis par des expéditions scientifiques ayant pour but essentiel la récolte de restes plus complets de ces reptiles fossiles fascinants, les Dinosaures.Aujourd'hui, par l'abondance, la variété et l'importance de ces gisements de Dinosaures, le Maghreb n'a rien à envier à la richesse paléontologique des Dinosaures d'Amérique du Nord ou d'Asie. La description de nouveaux genres et de nouvelles espèces de Dinosaures découverts ces dernières années dans le Nord de l'Afrique a changé complètement la vision que nous avions de ces grands reptiles mésozoïques, ainsi que la connaissance de leur histoire et de leur répartition géographique.Depuis la première découverte d'empreintes de Dinosaures dans le Sud algérien en 1880 jusqu'à la récolte la plus récente d'ossements de Dinosaures liasiques dans les montagnes du Haut Atlas marocain et avec l'exploration des sédiments du Cénomanien du désert égyptien, de nombreuses localités ont livré des Théropodes, des Sauropodes, des Ornithopodes nouveaux et splendides.Les gisements des pays du Nord de l'Afrique et spécialement ceux du Maghreb font partie maintenant des plus fameux gisements de Dinosaures connus dans le monde. Leurs faunes contribuent largement à...
