An extense systematic description of the Eocene larger foraminiferal faunas recorded in South Pyrenean Basin (Sierras Exteriores) is presented herein. The large dataset provided this work includes both Nummulites and Alveolina species, along with a variety other porcellaneous hyaline taxa lesser biostratigraphic relevance, are represented. foraminifera described correspond mainly to Lutetian (S...

The Eocene Jahrum Formation in High Zagros was studied Kuh-e- Soukhteh and North Gahrou sections (southwest of Shahrekord region, Chahar-mahal Bakhtiari Province). This formation, composed limestone, marl, dolomitic limestone (dolostone), accumulated on a marine platform within the Neo-Tethys ocean realm. It yields rich foraminiferal fauna, which three larger benthic assemblage zones were ident...

Although chrysophyte stomatocysts have a fossil record that likely extends to the lower Cretaceous, to date neither scales nor bristles of the scaled chrysophyte genera older than Holocene have been reported. This leaves the origin of this important group of freshwater algae a mystery. We discovered abundant and diverse scaled chrysophyte microfossils in ca. 47 Ma sediments (Middle Eocene, Lute...

The Eocene (~ 48.7 Ma, Ypresian-Lutetian) Princeton Chert of British Columbia, Canada, has long been recognized as a significant paleobotanical locality, and a diverse assemblage of anatomically preserved fossil plants has been extensively documented. Co-occurring fossil fungi also have been observed, but the full scope of their diversity has yet to be comprehensively assessed. Here, we present...

A biometric analysis of the lower teeth of Recent cow sharks (Hexanchidae) investigates the ontogenetic and phylogen− etic aspects of the dental characters employed by many ichthyologists and palaeontologists. The dental characters cur− rently used to separate two extant species of sixgill sharks (Hexanchus griseus and H. nakamurai) are analysed and the fossil record of their relatives reviewed...

The fossiliferous middle Eocene deposits of Sylhet Limestone Mikir Hills have yielded vertebrate and invertebrate faunas. fossil assemblages recorded in this contribution consist shark, ray, crocodile, conical tooth, broken fragments echinoderm spines. Ray crocodile tooth are reporting for the first time from Hills. Paleoenvironmental analysis based on fish assemblage association with (foramini...

New coleoid cephalopods are described from statolith remains from the Middle Eocene (Middle Lutetian) of the Paris Basin. Fifteen fossil statoliths are identified and assigned to the Sepiidae (Sepia boletzkyi sp. nov.,? Sepia pira sp. nov.), Loliginidae (Loligo clarkei sp. nov.), and Ommastrephidae (genus indet.) families. The sediments containing these fossils indicate permanent aquatic settin...

The collision of India with Asia, one of the most profound tectonic events to have occurred in past 100 m.y., is thought to have had geological, geochemical, and climatological consequences of global extent. Surprisingly the age of initiation of this collision remains poorly constrained. Estimates range from the Late Cretaceous (.65 Ma) to latest Eocene (,40 Ma), with little consensus in betwee...
