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]
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]
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]
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)
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]
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.
