Macrofossils and pollen representing forests of the pre-Taupo volcanic eruption (c. 1850 yr BP) era at Pureora and Benneydale, central North Island, New Zealand. [PDF]

, 1995
Micro- and macrofossil data from the remains of forests overwhelmed and buried at Pureora and Benneydale during the Taupo eruption (c. 1850 conventional radiocarbon yr BP) were compared. Classification of relative abundance data separated the techniques,

Stratigraphy of organic-rich deposits in floodplain environments: examples from the upper Odra river basin

Quaestiones Geographicae, 2012
. Macrofossil analysis and radiocarbon dating were used to determine the age, composition and succession pattern of organic-rich deposits infilling oxbows and flood basins in the Rivers Kłodnica, Odra and Osobłoga valleys (southern Poland). Both detrital

Van hoog naar laag: migratie van Myrica gale in het Holoceen

Belgeo, 2006
Already in the Boreal Myrica gale (gale; bog myrtle) formed a part of the vegetation of the Drents-Friese Plateau in the Northern Netherlands. During the Subboreal gale became more important.

Holocene Vegetation, Climate, and Carbon History on Western Kodiak Island, Alaska

Frontiers in Earth Science, 2019
At Phalarope Pond, western Kodiak Island, a multidisciplinary study using pollen and spores, macrofossils, stable isotopes, and carbon accumulation provides the Holocene vegetation and climate history following the deglaciation that began over 16,000 cal

Contribution of archaeobotany to understand taphonomic phenomena. The case of a Preboreal palaeochannel of Autrecourt-et-Pourron (Ardennes, France)

BSGF - Earth Sciences Bulletin, 2021
Palaeoecology, through the analysis of the interactions between environmental factors and ecosystems, refines the knowledge of the structuring process of plant communities and helps to understand the complexity of past environments.

Late Holocene palynology and palaeovegetation of tephra-bearing mires at Papamoa and Waihi Beach, western Bay of Plenty, North Island, New Zealand. [PDF]

, 1995
The vegetation history of two mires associated with Holocene dunes near the western Bay of Plenty coast, North Island, New Zealand, is deduced from pollen analysis of two cores.

First macrofossil record of Begonia (Begoniaceae) [PDF]

American Journal of Botany, 2011
Begonia is the sixth-largest genus of flowering plants, with about 1400-1500 species in 66 sections. Several species are popular with horticulturalists, mainly for their colorful flowers and leaves. However, the evolutionary history of the genus is debated, and until now there has been no macrofossil record.
