“…Moreover, various members of Ericaceae and Ilex are present and indicate acidic, oligotrophic conditions as frequently prevailing in swampy areas (Figueiral et al, 1998; van der Burgh, 1987). Peat scrub associations of the same taxonomic composition were also important in other Miocene brown coals (e.g., second Lusatian Seam, Poland; Ivanov & Worobiec, 2017; Worobiec, 2009). Tetracolporate morphotypes such as Tetracolporopollenites sapotoides referable to the Sapotaceae were likewise part of this shrub and are mainly distributed in the lower and middle part of the Main Seam (frequent up to ca.…”

“…Sciadopitys was identified based on needles in litter layers of the Main Seam brown coal (Kilpper, 1967) and as the most common tree of an in situ forest excavated from a stratigraphic level of the Frimmersdorf Seam at Hambach open cast (Mosbrugger et al, 1994) which is considered to represent a “ Sciadopitys raised bog” described by Schneider (1978, 1992) as one stage in the floral succession of Miocene peat vegetation in Central Europe. Also from other time‐equivalent brown coals of the southern North Sea Basin realm it is known as common element of the peat‐forming vegetation (e.g., Legnica, second Lusatian Seam of Lower Silesia, Worobiec, 2009).…”

Diversity patterns in microfloras recovered from Miocene brown coals of the lower Rhine Basin reveal distinct coupling of the structure of the peat‐forming vegetation and continental climate variability

Brown coal deposits of the Lower Rhine Basin, northwest Germany, cover the late Burdigalian to Serravallian and most of the Tortonian enabling access to observations of vegetation dynamics during the Miocene Climatic Optimum and Late Miocene Cooling. Based on a total of 500 microfloras sampled from brown coal seams in the Bergheim and Inden open cast mines, structural changes in the vegetation are studied in comparatively stable environments of persisting coastal mires. In order to minimize the impact of local edaphic conditions in the peat bog, the palynomorph record is characterized as diversity using plant functional types (PFTs). In total, 41 herbaceous and arboreal PFTs are assigned to pollen and spores types based on their botanical affinity.The diversity spectra reveal a variable proportion of herbaceous and shrubby PFTs attaining a mean of 30%, in both the middle and late Miocene sample sets. With ca. 70% of the total diversity attributable to arboreal functional types, the peat‐forming vegetation of the studied Miocene strata classifies as a swamp forest. The composition of the arboreal fraction shows a long‐term declining trend in the proportions of thermophilous evergreen types among broadleaved PFTs following the overall climate cooling throughout the studied time. Conifers became more diverse during the Langhian (ca. 15%, at a mean) and attained a high diversity level of ca. 20% of the total PFT diversity in the Tortonian. The diversity proportions of conifer PFTs among other arboreal components and the composition of the broadleaved angiosperm PFT fraction display a pointed short‐term variability that could probably be related to eccentricity cycles when considering the available independent stratigraphic framework. Our results suggest a distinct coupling of the structure of the peat‐forming vegetation and continental climate variability in the study area.

“…wood from the Bükkábrány fossil forest in Hungary (Erdei et al 2009;Bardet & Pournou 2015;Nikolouli et al 2016) and biomarkers (that may be indicative of fungi) have been extracted from North Alpine Foreland Basin and Lubstów deposit woods (Bechtel et al 2007;2008). Like initial research on the Brassington Formation, palynological studies of these sites have typically been focussed on the pollen and spore content to reconstruct vegetation, with fungal remains either left unidentified or subject to ongoing research (Boulter 1971;Erdei et al 2009;Worobiec 2009;Worobiec et al 2009;Pound & Riding 2016;Worobiec & Worobiec 2017). Continued palynological research, with a focus on identifying fungal remains to modern genera (where possible) rather than form taxa, will elucidate the full diversity and ecology of these Miocene warmer than present forests (Utescher et al 2007;Pound et al 2011).…”

Three new Miocene fungal palynomorphs from the Brassington Formation, Derbyshire, UK

et al. 2018

View full text Add to dashboard Cite

The Middle to Late Miocene Brassington Formation from the Peak District in Derbyshire, central UK, has yielded a diverse vegetation assemblage, but until now there have been no reports of fungal remains. Here we describe three new species of fossil fungal palynomorphs from the Kenslow Member of the Brassington Formation. The taxa have been assigned to the Chaetosphaeriaceae and Pyrenulales, respectively, and were most likely saprophytic members of the community. The extant living relatives of the new fossil fungi are commonly found on decaying wood, often submerged in freshwater. A saprobic ecology on submerged decaying wood is consistent with sedimentological evidence that shows the Kenslow Member was deposited in a lacustrine or wetland environment. This is the first reported occurrence of the genera Rhexoampullifera in the fossil record.

The mostly LM-based European pollen record documents two different morphotypes, the smaller Spinulaepollis arcethobioides Krutzsch and the larger Spinulaepollis major (Stuchlik) Stuchlik, suggesting the coexistence of at least two different Arceuthobium lineages during the Eocene to Miocene of Europe.…”

The continued investigation of the middle Miocene palynoflora from the Lavanttal Basin reveals numerous additional angiosperm taxa. The Myrtales to Ericales pollen record documented here comprises 46 different taxa belonging to (Rehderodendron) and Symplocaceae (Symplocos). Köppen signatures of potential modern analogues of the additional fossil woody elements confirm the hypothesis of a subtropical (Cfa, Cwa) climate at lower elevations and subsequent transition into a temperate climate with altitudinal succession (Cfa → Cfb/Dfa → Dfb; Cwa → Cwb → Dwbclimate). The fossil plants represent different vegetation units, from wetland lowlands to well-drained montane forests. Many of the fossil taxa have potential modern analogues that can be classified as nemoral and/or meridio-nemoral and/or semihumid-meridional vegetation elements. New is the recognition of oreotropical elements, which are direct indicators for a substantial altitudinal gradient.
