Palynofloral Change Through the Paleocene‐Eocene Thermal Maximum in the Bighorn Basin, Wyoming

open access: yesPaleoceanography and Paleoclimatology, Volume 38, Issue 12, December 2023., 2023
Abstract To better understand the effect of the Paleocene‐Eocene Thermal Maximum (PETM) on continental ecosystems, we studied 40 new palynological samples from the Bighorn Basin (BHB), northwestern Wyoming, USA. We see palm and fern abundances increase in the last 20–40 ka of the Paleocene, then dramatically with the onset of the carbon isotope ...

Assessing the use of mangrove pollen as a quantitative sea‐level indicator on Mahé, Seychelles

open access: yesJournal of Quaternary Science, Volume 36, Issue 2, Page 311-323, February 2021., 2021
Abstract We investigated the potential of mangrove pollen from Mahé, Seychelles, to improve existing metre‐scale Late Holocene sediment‐based sea‐level reconstructions. Mangrove species at two mangrove sites are broadly zoned according to elevation within the tidal frame.
