Substratum microtexture affects the boring pattern of , (Clionaidae, Demospongiae) orientation of fibrous aragonite crystals (.), or the parallel lamination within the .shell. Conversely, the homogeneous granoblastic, mosaic texture of Carrara marble was etched without preferred directions. SEM analysis showed that pit size also varies between the three substrates in relation to the respective substrate porosity.

Writing an Academic Paper in Englishigrating hydrocarbons, provides a ‘preservational window’ for studying a Late Palaeozoic microboring assemblage. The evaluation of thin-sections, bioclast surface features, and SEM analysis of epoxy resin casts reveals a total of 18 known ichnospecies and the new ichnotaxon .– reflecting the most di
