A climate model from 80 AD to 1350 AD for the Hautes Fagnes plateau (Belgium), based on pollen grains, testate amoebae and humification analyses. Application of the model to Subatlantic palaeolandslides in the Pays de Herve (eastern Belgium).

jeremy Beghin Alain Demoulin Philippe Gerrienne Emmanuelle Javaux Maurice Streel

The Misten bog is located on the Hautes Fagnes plateau (eastern Belgium). It includes thick peat deposit with more than 7 m of peat accumulation in ombrotrophic situation. Several palaeoclimatic and/or palaeohydrological proxies such as pollen grains, Sphagnum remains and testate amoebae have been fossilized under anoxic conditions. Several peat cores were retrieved from the bog during a study conducted by the University of Liege and the field laboratory of the Hautes Fagnes (DE VLEESCHOUWER et al., 2010). The peat was cored using a Wardenaar corer (for the top first meter) and a Belarus corer for the layers below. The Belarus sections of cores reached about 7.5 m in depth. The distance between cores 01 and 07, which are considered in this paper, is 1.5 m. The Belarus sections of cores 01 and 07 were correlated thanks to palynology and the analysis of the degree of humification.

A biostratigraphic method based on a quantification of the characters of Devonian tracheophytes

Paleobiology (1994)

Philippe Gerrienne Maurice Streel

Biostratigraphic applications of Devonian plant macrofossils are unusual because of the rarity of these fossil plants. Moreover, the taxonomic determination of these plants is too often either arguable or impossible. Here is proposed a biostratigraphic method based on a quantification of individual plant characters and not on determination of whole fossils. The method is the following: (1) each biocharacter found at a given locality receives a score according to whether it is primitive or derived, so that the biocharacter score increases with increasing derivation; (2) the biostratigraphic coefficients of well-dated localities are calculated, the biostratigraphic coefficient of a given plant locality being the mean of all the biocharacter scores of this locality; (3) the scores of these well-dated localities are used to build a reference scale to which localities under investigation will be compared. A detailed example is developed for Early Devonian times. Various plant biocharacters of seven fossiliferous outcrops have been quantified and the subsequent scores of these localities are presented. This example shows that biostratigraphic results obtained by using the quantification method are comparable in precision with dating based on palynological assemblage zones. Evolutionary aspects of the method are also discussed.

Early seed plant radiation: an ecological hypothesis

Geological Society London Special Publications (2010)

Cyrille Prestianni Philippe Gerrienne

Abstract The earliest steps of seed plant evolution have been extensively studied during the past 25 years. There is a growing body of evidence indicating that the first major spermatophyte radiation occurred during the Late Devonian. At least fourteen Late Devonian species are now recognized, and our knowledge of the diversity of those early seed plants has dramatically increased. Five morphotypes of seeds have been defined, mostly based on cupule morphology and on the number and degree of fusion of the integumentary lobes. In this paper, we critically discuss the abundant environmental information in order to characterize the environment in which this radiation occurred. Sedimentological information indicates that seed plants evolved in disturbed environments. It is suggested that early seed plants thrived in the shade of the dominating Archaeopteris , and that their evolution was canalized by this strong biotic pressure. We also confirm the previous suggestion that the variability of seed morphotypes can be explained by the weak abiotic selective pressure that existed in the Archaeopteris understory.
