reasonably diverse and fairly preserved palynoflora, dominated by land-derived palynomorphs (miospores) in association with minor marine entities, such as dinoflagellate cysts, foraminiferal test linings, and acritarchs, occur in surface samples of the hojedk formation, at the eshkeli stratigraphic section, north of kerman. spores with radiosymmetrical symmetry (trilete spores), bisaccate and m...

BACKGROUND The Middle Jurassic was a critical time in the evolutionary history of ichthyosaurs. During this time interval, the diverse, well-studied faunas of the Lower Jurassic were entirely replaced by ophthalmosaurids, a new group that arose sometime prior to the Aalenian-Bajocian boundary and by the latest middle Jurassic comprised the only surviving group of ichthyosaurs. Thus, the Middle ...

Microconchids are an extinct group of Spirorbis-like tentaculitoid tubeworms that dwelled in a variety of aquatic environments, ranging from normal marine, through brackish and hypersaline, to freshwater. An analysis of published microconchid occurrences focusing on their ecology and palaeoenvironmental distribution through geological time is conducted in order to establish the timing of microc...

The North Kitakami Belt in Northeast Japan mainly comprises accretionary complexes formed during the Jurassic to earliest Cretaceous. complex of is less studied compared age-equivalent Southwest Japan. Here, we provide additional data on formerly classified as Otori Unit, distributed northeastern part upper reaches Akka River Iwate Prefecture. Based detailed field mapping, clarified that Unit c...

Abstract The Jurassic rocks of Gebel Maghara, northern Sinai, Egypt, contain a well-preserved and highly diverse macrobenthic fauna, dominated by bivalves. This particularly bivalves gastropods, have received little attention in the last 100 years. In an attempt to provide sound database on marine bivalve diversity Egypt during period, first faunal group, protobranch bivalves, is reviewed detai...
