This illustration was commissioned by Professor Clay Tabor at the University of Connecticut, who in 2020 lead a study investigating the components of the debris cloud formed by the asteroid impact at the end of the Cretaceous period. Tabor et al. determined that while multiple types of debris helped form the ejecta cloud, soot emission from fires had the most devastating effect in reducing sunlight & therefore preventing plants & algae from photosynthesizing, resulting in ecological collapse.
