New evidence for the antiquity of Desmostylus (Desmostylia) from the Skooner Gulch Formation of California

Royal Society Open Science, 2023
Desmostylus is an extinct marine mammal genus that belongs to Desmostylia, a clade of extinct herbivorous mammals. While desmostylian remains are widely reported from Paleogene and Neogene marine strata of the North Pacific Rim, occurrences of the genus ...

On impact and volcanism across the Cretaceous-Paleogene boundary

Science, 2020
An impact with a dash of volcanism Around the time of the end-Cretaceous mass extinction that wiped out dinosaurs, there was both a bolide impact and a large amount of volcanism. Hull et al. ran several temperature simulations based on different volcanic

The Origin of the Legumes is a Complex Paleopolyploid Phylogenomic Tangle Closely Associated with the Cretaceous–Paleogene (K–Pg) Mass Extinction Event

Systematic Biology, 2020
The consequences of the Cretaceous–Paleogene (K–Pg) boundary (KPB) mass extinction for the evolution of plant diversity remain poorly understood, even though evolutionary turnover of plant lineages at the KPB is central to understanding assembly of the ...

Magnetostratigraphic study of a Late Cretaceous−Paleogene succession in the eastern Xining basin, NE Tibet: Constraint on the timing of major tectonic events in response to the India-Eurasia collision

GSA Bulletin, 2021
Cretaceous-Cenozoic basins developed in the NE Tibetan Plateau contain key archives to unravel the growth history of the plateau in response to the India-Eurasia collision.

The age sequence of the detrital zircons from the Guanyindian section in Longde, the northeastern margin of the Tibetan Plateau, and its geological significance

Dizhi lixue xuebao, 2021
The precise age of the strata at the northeastern margin of the Tibetan Plateau in the Paleogene-Neogene, and the initial time when the uplift of the Plateau affected its northeastern margin, have always been two main bone contentions among geologists ...

Registros paleógenos de glyptodontidae propalaehoplophorinae (xenarthra, cingulata) en áreas extrapatagónicas [PDF]

, 2016
Los registros paleógenos de Cingulata Glyptodontidae son muy escasos y los mejores conocidos provienen de la actual región patagónica de Argentina. Dos subfamilias han sido descritas: Glyptatelinae y Propalaehoplophorinae.

Streamlined islands and the English Channel megaflood hypothesis [PDF]

, 2015
Recognising ice-age catastrophic megafloods is important because they had significant impact on large-scale drainage evolution and patterns of water and sediment movement to the oceans, and likely induced very rapid, short-term effects on climate. It has

Oligocene plant assemblage from Rębiszów, Lower Silesia: First “volcanic flora” from Poland [PDF]

Acta Palaeontologica Polonica, 2020
Fossil plant macroremains preserved in laminated diatomites from Łysa Góra near Rębiszów, Lower Silesia, have been documented for the first time. The fossil assemblage consists mostly of leaves, but fruits, seeds and sporadic flowers also occur.

Early Cenozoic denudation of central west Britain in response to transient and permanent uplift above a mantle plume [PDF]

, 2018
Upwelling mantle plumes beneath continental crust are predicted to produce difficult to quantify, modest uplift and denudation. The contribution of permanent and transient components to the uplift is also difficult to distinguish.
