Journal ArticleDOI

Ricardo Martinez,Paul C. Sereno,Oscar A. Alcober,Carina E. Colombi,Paul R. Renne,Paul R. Renne,Isabel P. Montañez,Brian S. Currie +7 more
TL;DR: A previously unidentified basal theropod is described, its contemporary Eoraptor is reassessed as a basal sauropodomorph, the faunal record of the Ischigualasto Formation is divided with biozones, and the formation is bracketed with 40Ar/39Ar ages.
Journal ArticleDOI
Age of Etendeka flood volcanism and associated intrusions in southwestern Africa
TL;DR: In this paper, 40Ar/39Ar laser step-heating analyses of mineral separates from five volcanic units and five intrusions in Namibia yield important geochronological data for the Etendeka igneous province.
Journal ArticleDOI
State shift in Deccan volcanism at the Cretaceous-Paleogene boundary, possibly induced by impact.
Paul R. Renne,Paul R. Renne,Courtney J. Sprain,Courtney J. Sprain,Mark A. Richards,Stephen Self,Loÿc Vanderkluysen,Kanchan Pande +7 more
TL;DR: High-precision dating of Deccan Traps volcanic units suggests an increase in volcanism associated with the Chicxulub impact, which suggests postextinction recovery of marine ecosystems was probably suppressed until after the accelerated volcanism waned.
Journal ArticleDOI
Ecological and temporal placement of early Pliocene hominids at Aramis, Ethiopia
Giday WoldeGabriel,Tim D. White,Gen Suwa,Paul R. Renne,Jean de Heinzelin,William K. Hart,Grant Heiken +6 more
TL;DR: Radioisotopic dating, geochem-ical analysis of interbedded volcanic ashes and biochronological considerations place the hominid-bearing deposits in the Middle Awash research area of Ethiopia's Afar depression at around 4.4 million years of age.
Journal ArticleDOI
Early and Late Alkali Igneous Pulses and a High-3He Plume Origin for the Deccan Flood Basalts
TL;DR: Rocks from the older complexes show a 3He/4He ratio of 14.0 times the air ratio, an initial 87Sr/86Sr ratio of 0.70483, and other geochemical characteristics similar to ocean island basalts; the later alkalic pulse shows isotopic evidence of crustal contamination.
