The samples were spiked with modern <i>Lycopodium</i> spores for quantitative analysis. The number of <i>Lycopodium</i> encountered during the 200 count was recorded and used to calculate the quantitative value.</div> 2018-12-18 16:33:54 Eifelian Givetian spores acritarchs chitinozoans Biostratigraphy Palynology
