P-T reflections from the Anthropocene/The species we never knew by Tanya Yeomans

The Permian-Triassic (P-T) extinction event marks the boundary between the Paleozoic and Mesozoic eras. Also known as the ‘Great Dying’, scientists estimate that up to 96% of oceanic species became extinct. While the exact cause remains unknown, multiple contributing factors led to rising atmospheric carbon dioxide and global temperatures. This data visualization is intended to reflect upon this geologic boundary through textile work. The background of this data visualization is machine-stitched in patters representing oceanic rock strata across the two time periods. A red line separates the Permian and Triassic periods. Leading to this boundary are 100 hand-stitched lines representing oceanic species. Four lines - four percent of oceanic species make it across this threshold.
