Search for impact ejecta at the Paleocene–Eocene boundary
Meteoritics &Planetary Science, EarlyView.Abstract Almost 10 years have passed since microtektites and microkrystites were reported for the Paleocene–Eocene (P–E) boundary in drill cores and outcrop in New Jersey and in ODP Hole 1051B in the western North Atlantic. The glassy spherules were interpreted to reflect an impact trigger for the Paleocene–Eocene Thermal Maximum (PETM).

Terminal Eocene geological events in Turkey.
, 1986 It could be concluded that in the northern, central and southern as well as some parts of eastern Anatolia, the Late Eocene flysch sediments were uplifted, eroded and overlain disconformably by gypsum intercalated biogenic limestones, red beds and ...

Meteoritics &Planetary Science, EarlyView.Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.

Evolutionary legacies structure the geography of seagrass traits across the world's oceans
New Phytologist, EarlyView.Summary Traits modulate species' ability to track shifts in climate, yet the extent to which traits have been shaped by the contemporary environment and/or historical processes remains poorly understood. Here, we fill this gap for the world's seagrasses, habitat‐forming species that provide critical ecosystem services.

Carbonate facies, diagenesis and sequence stratigraphy of an eocene nummulitic seservoir interval (jdeir formation), offshore NW Libya [PDF]
, 2006 This study investigates the sedimentology, petrology and depositional environments of a major Early Eocene nummulitic reservoir unit: the Jdeir Formation, from offshore NW Libya in the Mediterranean Sea. This formation is a prolific hydrocarbon-producing

Plant Biology, EarlyView.Isoprene emission in oaks originated from convergent adaptive evolution of terpene synthases, involving a substrate shift from monoterpene to isoprene production within a Fagaceae‐specific TPS lineage. Abstract Plants emit a wide range of volatile organic compounds, among which isoprene is the most abundant and atmospherically influential. Although oak

, 2012 Back in the mid-1960s, I was a feral sort of a child who loved scampering around construc-tion sites, climbing the huge, grey piles of excavated shale that were popping up all over my rapidly developing Toronto suburb. I might have been six or so when I first really noticed the slabs of muddy smelling rock often contained the imprints of scallop ...
