CALCAREOUS PLANKTON HIGH RESOLUTION BIO-MAGNETOSTRATIGRAPHY FOR THE LANGHIAN OF THE MEDITERRANEAN AREA

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2008
High-resolution quantitative and qualitative analyses of the planktonic foraminifer and calcareous nannofossil content have been carried out on three Middle Miocene sections, from the Mediterranean area. Such sections (Cretaccio section, Tremiti Islands,

Firmground ichnofacies recording high-frequency marine flooding events (Langhian transgression, Vallés-Penedés Basin, Spain)

open access: yesGeologica Acta, 2005
The decapod burrow Spongeliomorpha sudolica occurs associated with transgressive firmgrounds in the transition between Aragonian continental red beds and Langhian marine units in some of the inner sectors of the Vallès-Penedès Basin.

EVOLUTION OF THE MEDITERRANEAN BASIN DURING THE LATE LANGHIAN - EARLY SERRAVALLIAN: AN INTEGRATED PALEOCEANOGRAPHIC APPROACH

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2002
An integrated (multidimensional) faunal and geochemical dataset has been generated by the study of a Middle Miocene sedimentary section (Ras il Pellegrin) outcropping in the Malta Island (central Mediterranean) and referred to the Late Langhian-Early ...

A digital redescription of the Middle Miocene (Langhian) carettochelyid turtle Allaeochelys libyca [PDF]

open access: yesFossil Record
Allaeochelys libyca is a carettochelyid turtle from the Middle Miocene of Libya. The species is the only valid carettochelyid taxon recovered from Africa and was named based on fragmentary material that includes a partial cranium and isolated ...

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The First Complete Chloroplast Genome of <i>Lycium shawii</i>: Genomic Architecture, Molecular Phylogenetics and Evolutionary Insights. [PDF]

open access: yesEcol Evol
The study presents the first complete chloroplast genome of Lycium shawii (PQ824997.1) spanning 155,936 bp and contains 128 genes (84 protein‐coding genes, 36 tRNAs, and eight rRNAs). Nucleotide diversity analysis highlighted atpI, rbcL, and accD as hypervariable loci suitable for DNA barcoding. Molecular dating analysis revealed that L.

Burdigalian-Langhian foraminifera of the northwest High Zagros Thrust Belt, southwest Iran [PDF]

open access: yesGeologos, 2021
Abstract The foraminiferal contents of the lower–middle Miocene succession exposed in three sections in north Nur Abad on the northwestern side of the High Zagros Thrust Belt were studied. Assemblages of larger foraminifera from these sections can be referred to Zone SBZ 25 (and the Miogypsina globulus and Miogypsina intermedia subzones),

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]

open access: yesPlant Environ Interact
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

MIDDLE MIOCENE DROWNED RAMP IN THE VICINITY OF MARIJA BISTRICA (NORTHERN CROATIA)

open access: yesRudarsko-geološko-naftni Zbornik, 2018
Fossiliferous Middle Miocene deposits from the surroundings of Marija Bistrica (north-east of Zagreb) transgressively overly older pre-Cenozoic bedrocks. Fossils from shallow marine environments are in most cases preserved as bioclasts, while deep marine

The West African enigma: Systematics, evolution, and palaeobiogeography of cardiid bivalve Procardium [PDF]

open access: yesActa Palaeontologica Polonica, 2017
Procardium gen. nov. is proposed for a group of early Miocene to Recent large cardiids in the subfamily Cardiinae. The type species is Cardium indicum, the only living representative, previously assigned to the genus Cardium.
