The data presented here provide the first high-resolution investigation of carbon isotope and
geochemical analyses derived from the Pliensbachian-Toarcian boundary, of Issouka …

Abstract In the Moroccan Atlas, sedimentary deposits provide important data on reef events
that characterize the Jurassic period. Recent work allows us to enhance knowledge of the …

The shallow-water carbonates of the Middle Eocene in northern Egypt represent a Tethyan
reef-rimmed carbonate platform with bedded inner-platform facies. Based on extensive …

Strophodus is a speciose and geographically widespread taxon of large durophagous
hybodontiform chondrichthyan, with a stratigraphic range extending from Middle Triassic to …

The thiolliericrinids (Thiolliericrinidae) are comatulids (Comatulida), which retained their
stalks as adults. Here, we report a centrodorsal from the Bajocian strata (Middle Jurassic) of …

The early Bajocian environmental crisis is marked by floral and faunal turnovers, and a
positive carbon excursion recognized in both marine and continental archives. In the basinal …

The thiolliericrinids (Thiolliericrinidae) are comatulids (Comatulida), which retained their
stalks as adults. Here, we report a centrodorsal from the Bajocian strata (Middle Jurassic) of …

Here, we provide a detailed facies and depositional record from a NE-SW-directed, 250-km-
long transect across a distally steepened, Middle Jurassic carbonate ramp in the northern …

Following the extinction event at the Triassic–Jurassic boundary and during the
Pliensbachian–Toarcian events, coral reef builders were severely affected, and the number …

Résumé La coupe d'Aït Athmane est située dans la partie sud-est du Haut Atlas central, à
