Macrobenthic organisms - trace fossil interactions in the Lower Carboniferous Culm Basin (Drahany Upland and Nízký Jeseník Mts. of the Czech Republic)

Original language description

The Lower Carboniferous Culm facies of the Moravo–Silesian Unit (Bohemian Massif) preserves thick siliciclastic turbidite successions of the Rhenohercynian Variscan Culm Basin. In the Drahany Upland the most fossiliferous beds are in outcrops of the Myslejovice Fm. (upper Viséan). The Moravice Fm. (upper Viséan) of the Nízký Jeseník Mts. could be the sedimentary basin equivalent for the Myslejovice Fm. in similar fauna and ichnofauna findings but with some differences in the composition of fossil fauna associations.The aim of this short study is to test whether fossil tracks and macrofossils are often found in close proximity and whether there was direct exploitation and use of the organic matter of dead and buried organisms by the originators of the fossil tracks.Microbial coatings, or biofilms, are often poorly associated with impacts on trace fossils or fossil associations due to the lack of paleontological record. Both in the Drahany Upland and in the Nízký Jeseník Mts. (specifically in the Moravice Fm.) there is only indirect evidence of the dependence of macroorganisms on bacterial coatings. These may be some irregularities occurring in the clay and dusty layered surfaces, which may have been misinterpreted in the past and may belong to microbial coatings based on the similarity of morphology. Bacterial activity often contributes to sediment stabilisation (Gerdes et al., 2000), which could explain the highly diverse communities of trace fossils and fossil remains found at certain sites in the Moravian-Silesian Culm Basin.
