Plant macrofossils, ichnofossils, facies analysis and palaeoenvironment interpretation of the Hojedk Formation in the north of Kerman (Central Iran) [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2019
This study led to identify 30 species and 16 genera of eight different plant macrofossils orders including Equisetales, Cycadales, Bennettitales, Coniferales, Peltaspermales, Ginkgoales, Corystospermales, and Filicales at the Deh-Shiykh section, north of

Early Holocene plant macrofossils indicate cool refugia for subalpine plant taxa in Acadia National Park, Maine

open access: yesFrontiers in Ecology and Evolution, 2023
Identifying refugia— specifically places where species can persist during periods of regionally unsuitable climate— is increasingly important for conservation practitioners and land managers charged with protecting biodiversity in a rapidly warming world.

Cenozoic plant macrofossil sites ofTasmania [PDF]

open access: yesPapers and proceedings of the Royal Society of Tasmania, 2002
Tasmania has an outstanding Cenozoic plant fossil record, including several sites of international significance. This paper provides a compendium of macrofossil sites and associated literature. Macrofossils (leaves, fruit, flowers, wood) are known from 59 sites, ranging from Early Eocene to Late Pleistocene in age. Most are Palaeogene to early Neogene,

A multi-proxy long-term ecological investigation into the development of a late Holocene calcareous spring-fed fen ecosystem (Raganu Mire) and boreal forest at the SE Baltic coast (Latvia)

open access: yesEcological Indicators, 2021
The calcareous substrate of spring-fed fens makes them unique islands of biodiversity, hosting endangered, vulnerable, and protected vascular plants.

Towards a radiocarbon chronology of the Late-Glacial: Sample selection strategies [PDF]

open access: yes, 2001
This paper outlines a dating program designed to test the reproducibility of radiocarbon dates on different materials of Late-Glacial age (plant macrofossils, fossil beetle remains, and the "humic" and "humin" chemical fractions of limnic sediments ...

Holocene vegetation history of the Western Rhodope Mountains (South Bulgaria): the paleoecological record of peat bog Beliya Kanton

open access: yesActa Palaeobotanica, 2023
Pollen and plant macrofossil analyses supported with radiocarbon dating were conducted on a Holocene core from the peat bog Beliya Kanton (1547 m a.s.l.) located in the Western Rhodope Mountains (South Bulgaria).

Testing the use of bomb radiocarbon to date the surface layers of blanket peat [PDF]

open access: yes, 2004
The recently formed surface layers of peatlands are archives of past environmental conditions and can have a temporal resolution considerably greater than deeper layers.

Messinian vegetation and climate of the intermontane Florina–Ptolemais–Servia Basin, NW Greece inferred from palaeobotanical data: how well do plant fossils reflect past environments? [PDF]

open access: yesRoyal Society Open Science, 2020
The late Miocene is marked by pronounced environmental changes and the appearance of strong temperature and precipitation seasonality. Although environmental heterogeneity is to be expected during this time, it is challenging to reconstruct ...

High-resolution coproecology: Using coprolites to reconstruct the habits and habitats of New Zealand’s extinct upland Moa (Megalapteryx didinus) [PDF]

open access: yes, 2005
Knowledge about the diet and ecology of extinct herbivores has important implications for understanding the evolution of plant defence structures, establishing the influences of herbivory on past plant community structure and composition, and identifying
