On Prophoca and Leptophoca (Pinnipedia, Phocidae) from the Miocene of the North Atlantic realm : redescription, phylogenetic affinities and paleobiogeographic implications [PDF]

open access: yes, 2016
Background: Prophoca and Leptophoca represent the oldest known genera of phocine seals, dating from the latest early to middle Miocene. Originally, Prophoca rousseaui and Prophoca proxima were described based on fragmentary remains from the Miocene of ...

Tectonic control for evaporite formation in the Eastern Betics (Tortonian; Spain)

open access: yesSedimentary Geology, 2006
Tectonic uplift and sea level lowering are two proposed mechanisms to explain the development of thresholds in front of the widespread evaporite basins of the circum-Mediterrranean region during the Miocene. Here we apply a multi-disciplinary approach to the continuously marine sequences of the Murcia–Cartagena basin to investigate which mechanism is ...

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.

Orbital frequencies in the carbonate sedimentary record: distorted by diagenesis? [PDF]

open access: yes, 2004
The most important archive of Earth’s climate change through geologic history is the sedimentary rock record. Rhythmic sedimentary alternations are usually interpreted as a consequence of periodic variations in the orbital parameters of the Earth.

Using high-resolution stratigraphy and structural analysis to constrain a “polyphase” tectonics in wedge-top basins. Inferences from the Late Tortonian Scillato Basin (central-northern Sicily). [PDF]

open access: yes, 2012
The present paper aims to show, both from a stratigraphic and structural points of view, the main features of a wedge-top syntectonic basin which evolved recording polyphase and non-coaxial tectonics.

The implications of K-Ar glauconite dating of the Diest Formation on the paleogeography of the Upper Miocene in Belgium [PDF]

open access: yes, 2014
The glauconite-rich Diest Formation in central and north Belgium contains sands in the Campine subsurface and the hilly Hageland area that can be distinguished from each other.

The role of extension in the Miocene denudation of the Nevado-Filábride Complex, Betic Cordillera (SE Spain) [PDF]

open access: yes, 2004
The Internal Zone of the Betic Cordillera, SE Spain, consists of a nappe stack of three complexes, the deepest of which is the Nevado-Filábride Complex.

First occurrences of Trionychidae (Testudines, Cryptodira) from the Miocene of Poland: Detailed cranial anatomy and biogeographic implications

open access: yesJournal of Anatomy, EarlyView.
Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical

Stratigraphy of Cretaceous to Lower Pliocene sediments in the northern part of Cyprus based on comparative 87Sr/86Sr isotopic, nannofossil and planktonic foraminiferal dating [PDF]

open access: yes, 2012
New age data from Sr isotope analysis and both planktonic foraminifera and nannofossils are presented and discussed here for the Upper Eocene–Upper Miocene sedimentary rocks of the Değirmenlik (Kythrea) Group.

A Tortonian onset for the Algerian margin inversion: Evidence from low‐temperature thermochronology [PDF]

open access: yesTerra Nova, 2018
AbstractIn North Africa, the Algerian margin is made of basement blocks that drifted away from the European margin, namely the Kabylia, and docked to the African continental crust in the Early Miocene. This young margin is now inverted, as dated Miocene (17 Ma) granites outcrop alongshore, evidencing kilometre‐scale exhumation since their emplacement ...
