| Summary: | The dataset includes an Excel file with sporomorph counting of samples from the Stensiöfjellet section, Svalbard. Furthermore, it includes additional taxonomic notes on conodonts from the Stensiöfjellet section, Svalbard. ... : Two main sections were logged and samples taken: Stensiöfjellet A and Stensiöfjellet C sections, ca. 1.2 km apart. For conodonts, we collected 17 samples, each weighing approximately 10kg, from section Stensiöfjellet C. Of the 17 samples, 11 were taken from the Lusitaniadalen Member and 6 from the Vendomdalen Member, with varying spacing between samples ranging from 1 m to 60 m. The samples were dissolved using a ~ 10% buffered acetic acid solution following the procedure described by Jeppsson et al. (1999). The residues were concentrated by using sodium polytungstate (Jeppsson & Anehus 1999) as a heavy liquid for separation. They were then sieved using a 0.075-mm mesh, and the heavy fraction was handpicked under a binocular microscope. The selected conodont elements were illustrated using a scattered electron microscope (SEM) (JEOL JSM-6010) without the use of a sputter coater and a digital microscope (Keyence VHX 6000). For palynological analysis, samples (n = 61 Stensiöfjellet A, Fig. 1) were cleaned, ... |
