Palynology and vegetation dynamics across the Permian–Triassic boundary in southern Tibet
, 2020 The end-Permian mass extinction (EPME) is regarded as the most severe biotic crisis in Earth history, which is particularly well-documented in the marine fossil record. Despite compelling evidence that dramatic global environmental changes probably drove

A Survey of Atmospheric Pollen and Spores in North-Western Nigeria
Notulae Scientia Biologicae, 2018 The incidence of airborne pollen occurring as aeroallergens of varied levels at different periods of the year has generated some public health concern globally. The present study was conducted in order to examine the monthly depositional rate of airborne

Palynology from Ground Zero of the Chicxulub Impact, Southern Gulf of Mexico
Palynology, 2020 Palynological analysis of Site M0077A in the Chicxulub impact crater has yielded a record of the immediate Cretaceous/Paleogene (K/Pg) recovery from ground zero of the end-Cretaceous mass extinction, followed by a record of the Paleocene–Eocene Thermal ...

Tanzania Journal of Science, 2019 The major challenge to the current understanding of the stratigraphy of the Tanga Basin is scarcity of biostratigraphy age-control data. A number of palynomorphs retrieved from core samples of the Tanga Beds and analysed for palynology are here presented.

Southern Ocean warming and Wilkes Land ice sheet retreat during the mid-Miocene
Nature Communications, 2018 Ocean heat is important in forcing ice sheet retreat, yet past ocean temperature data from proximal ice sheet locations are sparse. Here, the authors present temperature reconstructions from the Wilkes Land subglacial basin during the mid-Miocene, and ...

Forensic palynology and the search for geolocation: Factors for analysis and the Baby Doe case.
Forensic Science International, 2019 First used over 50 years ago, forensic palynology is an important tool for law enforcement agencies. In most countries that use forensic palynology, microscopic pollen grains and spores are traditionally used in criminal investigations to link suspects ...
