Analyzed δ13Corg values from two North American sites across the Toarcian Oceanic Anoxic Event. Highest-resolution study of Toarcian carbon isotope excursions from outside of Europe. Documented small-scale carbon isotope excursions during onset of Toarcian carbon isotope excursion. Small-scale carbon isotope excursions during Toarcian were global phenomena. Increased terrestrial methanogenesis implicated in global warming and carbon isotope excursions.
