The lithostratigraphy and ammonite/ostracod biostratigraphy the accompanying fauna of several sections outcrops around Hohenzollern (Zollernalb, SW Germany), ranging from topmost Opalinuston Formation (uppermost Lower Aalenian) to basal Wedelsandstein (lowermost Bajocian) are described analyzed. study ostracods 41 samples Aalenian Bajocian Heiligenbach, Hausterberg Roschbach has yielded approxi...

Middle Jurassic (Bajocian-Bathonian) Sphenophyta fossils of the silicified level peats of the Pabdana Coal Mine (Kerman) recovered. Four new species of Sphenophyta described for the first time. They include Equisetites pabdanaii sp. nov., Equisetites sparseii sp. nov., Equisetites hojedkii sp. nov. and Equisetites irregularii sp. nov.,. Descriptions of the above mentioned new species has been d...

Three ammonites; Ermoceras cf. coronatoides Douvillé, Teloceras labrum Buckman, and Normannites gr. braikenridgii (Sowerby); have been recorded for the first time from latest early Middle, to Late Bajocian of Wadi Huni biomicritic marly limestone Zerqa in Dier-Alla area. This fossil fauna is comparable with other levant countries.

Abstract Strophodus is a speciose and geographically widespread taxon of large durophagous hybodontiform chondrichthyan, with stratigraphic range extending from Middle Triassic to the Early Cretaceous. Here, we describe new species , S . atlasensis sp. nov., based on an incomplete articulated dentition recovered marine Bajocian deposits eastern High Atlas Mountains in Morocco. The diagnosed by ...

Volcaniclastic accumulations in shallow marine environments are prone to be eroded and transported by sedimentary agents then resedimented either on contemporaneous or younger substrates. Therefore, dating of the volcanic events through sediments containing interbedded layers can lead errors. A case study volcanism southeastern Iberian Range during Early Middle Jurassic is presented. Precise ho...

A new homolodromioid, Tanidromites maerteni, the earliest member of the genus and family, is recorded from the lower upper Bajocian (Niortense Zone) of Calvados, northwest France. It is noted that carapace morphologies of other Jurassic brachyuran taxa within the family Prosopidae are closely similar to those of tanidromitids, and that diagnoses of recently erected Jurassic families and genera ...
