Hard substrate communities across the K–Pg boundary

Abstract

This thesis compares the ecologies of hard substrate communities across the K–Pg boundary. As suspension feeders, hard substrate fauna are expected to be particularly susceptible to the hypothesised photosynthesis crash at this time. Encrusting organisms from K–Pg sections in the SE USA, Denmark, the Netherlands and the Antarctic are utilised, in order to examine trends across the mass extinction in different regions
