Time Scales of Critical Events Around the Cretaceous-Paleogene Boundary
Paul R. Renne,Paul R. Renne,Alan L. Deino,Frederik J Hilgen,Klaudia F. Kuiper,Darren F. Mark,William S. Mitchell,Leah E. Morgan,Roland Mundil,Jan Smit +9 more
TL;DR: Radiometric dating establishes the mass extinction that killed the dinosaurs as synchronous with a large asteroid impact between the Cretaceous-Paleogene boundary and associated mass extinctions with the Chicxulub bolide impact to within 32,000 years.

TL;DR: The 40Ar/39Ar dating method is among the most versatile of geochronometers, having the potential to date a broad variety of K-bearing materials spanning from the time of Earth's formation into the historical realm.
Early levallois technology and the lower to middle paleolithic transition in the southern caucasus
Daniel S. Adler,Keith Wilkinson,Simon Blockley,Darren F. Mark,Ron Pinhasi,Beverly A. Schmidt-Magee,Samvel Nahapetyan,Carolina Mallol,Francesco Berna,P. J. Glauberman,Yannick Raczynski-Henk,Nathan Wales,Nathan Wales,Ellery Frahm,Olaf Jöris,Alison MacLeod,Victoria C. Smith,Victoria L. Cullen,Boris Gasparian +18 more
TL;DR: The data from Nor Geghi 1, Armenia, record the earliest synchronic use of bifacial and Levallois technology outside Africa and are consistent with the hypothesis that this transition occurred independently within geographically dispersed, technologically precocious hominin populations with a shared technological ancestry.

Ar–Ar dating of authigenic K-feldspar: Quantitative modelling of radiogenic argon-loss through subgrain boundary networks
Darren F. Mark,Darren F. Mark,Simon P. Kelley,Martin Lee,John Parnell,Sarah C. Sherlock,David J. Brown +6 more
TL;DR: In this article, two distinct generations of authigenic K-feldspar in Fucoid Bed sandstones from An-t-Sron and Skiag Bridge, NW Highlands, Scotland, have experienced post-growth heating to levels in excess of the predicted Ar-closure temperature.

Heaton,María del Carmen Arriaza +21 more
TL;DR: The morphology and size of its constituent parts suggest that the fossils derived from an extremely robust individual who, at 1.338±0.024 Ma (1 sigma), represents one of the most recent occurrences of Paranthropus before its extinction in East Africa.
