Acrostichum is considered today an opportunistic fern in disturbed areas, which indicates the first stages of colonisation of such zones. However, in the fossil record, Acrostichum appears related to fluvio-lacustrine environments, freshwater marshes and mangrove deposits. We report here for first time fossil evidence of Acrostichum that reveals a pioneering behaviour of this fern in the coloni...
Background and Objectives: ?????? Methods: ?????? Findings: ?????? Conclusion: ????? The present study is the first study aimed at biostratigraphy based on calcareous nannoplankton that has been performed on all succession exposed from the Oligo-Miocene marine deposits (members a to f of the Qom Formation). The studied deposits are located in the middle part of the Central Iran Zone and m...
Abstract The Oligocene and Miocene tectonic biogeographical alterations of the peri-Mediterranean area could strongly impact speciation processes migrations Mediterranean sandfly species. To understand possible former role this palaeobiogeographic factor on ancestral species, potential suitability values five Larroussius , two Paraphlebotomus one Phlebotomus species were modelled from Rupelian ...
In the previous paper, geological ages of Late Cretaceous, Paleocene, late Middle to Eocene, Oligocene and early Early Miocene were confirmed at first time, based on occurrences both age diagnostic larger foraminifera associated planktonic foraminifera, from Sashida Limestone included basalt pebbles, Sashida, Kamo-Gun, south Izu Peninsula. Therefore, was made up clastic carbonate rocks various ...
