Environmental Context of Hominin Foot Evolution. [PDF]

open access: yesAm J Biol Anthropol
ABSTRACT Objectives This study investigates the environmental contexts that influenced the evolution of hominin foot morphology, focusing on when, where, and under what conditions key synapomorphies evolved. We test whether shifts in ecological conditions are associated with changes in locomotor function.

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

New species of Omma Newman from mid-Cretaceous Burmese amber (Coleoptera, Archostemata, Ommatidae) [PDF]

open access: yesDeutsche Entomologische Zeitschrift, 2021
A new fossil species of the extant archostematan genus Omma Newman, O. forte sp. nov., is reported from mid-Cretaceous amber from northern Myanmar. The extinct ommatid genus, Cionocups Kirejtshuk from the same deposit, is considered as a junior synonym ...

Limnomma, a new genus of Ommatidae from the Middle Jurassic Daohugou beds (Coleoptera, Archostemata) [PDF]

open access: yesDeutsche Entomologische Zeitschrift, 2021
The relictual archostematan beetle family Ommatidae attained high diversity during the Mesozoic. Despite their once high taxonomic diversity and morphological disparity, many Mesozoic ommatid taxa remain poorly understood, partly due to limited ...

A multi-dimensional dataset of Ordovician to Silurian graptolite specimens for virtual examination, global correlation, and shale gas exploration [PDF]

open access: yesEarth System Science Data, 2023
Multi-elemental and multi-dimensional data are more and more important in the development of data-driven research, as is the case in modern paleontology, in which, in an examination by experts, or some day artificial intelligence, every fossil specimen ...

Chronological characteristics for snow accumulation on Styx Glacier in northern Victoria Land, Antarctica

open access: yesJournal of Glaciology, 2020
Under the potential to reconstruct the past climatic and atmospheric conditions from a deep ice core in the coastal Antarctic site (Styx Glacier), an 8.84 m long firn core (73°50.975′ S, 163°41.640′ E; 1623 m a.s.l.) was initially studied to propose a ...
