Study of carbon isotopes of organic matter in conodont elements seems to be a promising approach in reconstruction of the ancient pelagic ecosystems and in isotope stratigraphy. Evaluation of influence of thermal maturity on the isotopic composition of organic matter (d13Corg) in conodonts is an actual problem. Experimental study demonstrates that thermal maturity of conodont elements in the Conodont Alteration Index (CAI) interval from 1 to 4 causes d13Corg depletion varying from 0.2 up to 2.6 ‰. The depletion is much less than changes in conodont d13Corg caused by the vital effect. Thus, conodont elements with CAI
