This folder contains SEM data from six fossil-bearing surfaces in Newfoundland, alongside two publications that have arisen from the datasets. SEM data were collected from carbon-coated thin sections through sedimentary samples from Ediacaran bedding planes in Newfoundland. The data are divided by thin section/surface, and each sub-folder contains images (.BMP format), text files, spot point counts (as .emsa files), and .SIF files. The ‘NSSProject’ file (.xml) contains broader project data. The thin sections analysed originate from sedimentary samples collected prior to the start of this IRF, collected under permits issued by the Government of Newfoundland and Labrador. Each folder name corresponds to the following thin section in the collections at the Department of Earth Sciences, University of Cambridge: Folder name Thin section studied Geological information Current location in Cambridge Earth Sciences, office N321 BR5 2013 BR5 2013 Briscal Fm, MPER Slide drawer NL14 BR5 2014 BR5 2014 Briscal Fm, MPER Slide drawer NL14 LC5 – H14 N12-LC5-1 Trepassey Fm, Little Catalina Slide drawer NL12.2 LC6 N14-LC6-1 Trepassey Fm, Little Catalina Slide drawer NL14 LC13 N14-LC13-1 Trepassey Fm, Little Catalina Slide drawer NL14 MP2 E Surface 3309-9 Mistaken Point Fm, MPER Slide drawer NL11.2 PU10 - MUN N12-PU10-1 Trepassey Fm, Burnt Point, Port Union Slide drawer NL12.1 The date in the folder name (December 2014 or January 2015) indicates the month in which SEM analysis of that specimen took place. Data were collected to examine the mineralogy and sedimentology associated with fossil-bearing surfaces in Newfoundland. These data will be of interest to those researching Ediacaran taphonomy, sedimentology, and petrology. Dr Alex Liu, with the assistance of Dr Stuart Kearns and Dr Ben Buse (University of Bristol), collected the data.
