The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary
TLDR
Records of the global stratigraphy across this boundary are synthesized to assess the proposed causes of the Cretaceous-Paleogene boundary and conclude that the Chicxulub impact triggered the mass extinction. Expand
Geochemical and mineralogical investigation of the Permian-Triassic boundary in the Continental Realm of the Southern Karoo Basin, South Africa
Mineralogical and geochemical studies of the non-marine Permian–Triassic (P–Tr) boundary across two stratigraphically wellconstrained sections (Commando Drift Dam and Wapadsberg, Eastern Cape… Expand
Indication of Global Deforestation at the Cretaceous-Tertiary Boundary by New Zealand Fern Spike
TLDR
Recovery of New Zealand plant communities followed a pattern consistent with major climatic perturbations occurring after an impact winter that was possibly preceded by global wildfires. Expand
The global vegetation pattern across the Cretaceous-Paleogene mass extinction interval: A template for other extinction events
Abstract Changes in pollen and spore assemblages across the Cretaceous–Paleogene (K–Pg) boundary elucidate the vegetation response to a global environmental crisis triggered by an asteroid impact in… Expand
Pollen and spores in marine Cretaceous/Tertiary boundary sediments at mid‐Waipara River, North Canterbury, New Zealand
Abstract Terrestrial pollen and spores in late Maastrichtian to early Paleocene marine strata at mid‐Waipara, New Zealand, permit reconstruction of contemporary vegetation and paleoclimates. During… Expand
A new terrestrial Cretaceous-Paleogene site in New Zealand—turnover in macroflora confirmed by palynology
A fluvial sequence near Cave Stream (north of Castle Hill Village, central Canterbury), New Zealand, contains organically-preserved plant macrofossils (cuticles). The almost ubiquitous presence of… Expand
Fossilized Nuclei and Chromosomes Reveal 180 Million Years of Genomic Stasis in Royal Ferns
TLDR
An exquisitely preserved, calcified stem of a royal fern (Osmundaceae) from Early Jurassic lahar deposits of Sweden is presented in which authigenic mineral precipitation from hydrothermal brines occurred so rapidly that it preserved cytoplasm, cytosol granules, nuclei, and even chromosomes in various stages of cell division. Expand
Early Jurassic annelid cocoons from eastern Australia
A small assemblage of clitellate annelid cocoons (egg cases) is described from the Early Jurassic Marburg Subgroup, Clarence-Moreton Basin, eastern Australia. Two complete specimens are preserved on… Expand
An Early Jurassic flora from the Clarence-Moreton Basin, Australia
A low-diversity Early Jurassic flora preserved in floodbasin siltstones of the Marburg Subgroup at Inverleigh Quarry in the Clarence-Moreton Basin, eastern Australia, is dominated by Allocladus… Expand
Age and pattern of the southern high-latitude continental end-Permian extinction constrained by multiproxy analysis
TLDR
A multi-proxy Permo-Triassic record from Australia is reported, resolving the timing of local terrestrial plant extinction and the relationship with environmental changes, andPalaeoclimate modelling suggests a moderate shift to warmer summer temperatures and amplified seasonality in temperature across the EPE, and warmer and wetter conditions for all seasons into the Early Triassic.
