• A negative carbon isotope excursion at Paleocene-Eocene boundary in Jaisalmer Basin has been recognized for the first time. Besides excursion at P-E transition, short but significant negative carbon isotope shift has also been observed preceding the Paleocene-Eocene thermal maximum (PETM). The study discusses the possible mechanism for PETM and pre-CIE warm conditions in Jaisalmer Basin, India.
