This study presents a fossil signature based on fractal dimension (FD) derived from computerized tomogra­phy (CT) images to differentiate between coprolites and body fossils. Coprolites are generally studied using destructive techniques like thin section study and geoche­mistry. Coprolites and body fossils collected from the Triassic terrestrial Gondwana deposits of India were chosen for the study. The presented CT-powered FD-based digital signature can properly distinguish coprolites from other fossils, without losing the structural features of the samples. The present study will further enhance the digitalized fossil research

Abstract


This study presents a fossil signature based on fractal dimension (FD) derived from computerized tomogra­phy (CT) images to differentiate between coprolites and body fossils. Coprolites are generally studied using destructive techniques like thin section study and geoche­mistry. Coprolites and body fossils collected from the Triassic terrestrial Gondwana deposits of India were chosen for the study. The presented CT-powered FD-based digital signature can properly distinguish coprolites from other fossils, without losing the structural features of the samples. The present study will further enhance the digitalized fossil research
