The Upper Bajocian- Lower Bathonian succession in the Kopet-Dagh Basin of NE Iran represents fluvio-deltaic to turbidite deposits. The Kashafrud Formation provides an excellent opportunity to study the interplay between deep-water sedimentation and syndepositional tectonic subsidence (or uplift) in the region. The effects of these processes caused sea-level changes, variation in depositional se...

This paper presents evidence on Mesozoic inversion of basin bounding faults within the Taleqan-Gajereh-Lar Paleograben (TGLP) in Central Alborz Range. For this purpose, well documented stratigraphy data across the TGLP together with the new acquired structural data on the geometry and kinematics of the paleograben basin bounding faults are utilized. The TGLP has evolved through the Early and Mi...

Even though a handful of long-lived reptilian clades dominated Mesozoic marine ecosystems, several biotic turnovers drastically changed the taxonomic composition these communities. A seemingly slow paced, within-geological period turnover took place across Early–Middle Jurassic transition. This saw demise early neoichthyosaurians, rhomaleosaurid plesiosaurians and plesiosauroids in favour ophth...

The Cabeço da Ladeira paleontological site in central Portugal became known as the “Jurassic Beach”. Formerly an active quarry, was protected order to preserve large exposures of a Middle Jurassic (early? Bajocian) carbonate tidal flat with outstanding fossil record. This multidisciplinary work involving experts from several national and international research geoconservation institutions carri...
