Carbon isotopic compositions of organic matter across continental Cretaceous–Tertiary (K–T) boundary sections: Implications for paleoenvironment after the K–T impact event

@RadPlanets @toomanyspectra I'd never heard of K/T boundary coal before - it's a great pic. If I understand this paper by Koeberl & co, they indicate massive N-fertilised algal blooms in freshwater environments just after (within 10 years) of the impa
