En este trabajo se reporta la presencia de elementos del aparato bucal y posibles estructuras asociadas en un amonite de la especie Maorites seymourianus de la Formación López de Bertodano (Cretácico Tardío, Península Antártica), y se discuten los procesos tafonómicos que habrían permitido esta preservación excepcional. Esta es la primera descripción de estas estructuras para la familia Kossmaticeratidae. Para este estudio se empleó una técnica denominada Reflectance Transformation Imaging (RTI) relativamente poco aplicada en estudios paleontológicos, por lo que se provee una breve revisión del método y se indica su potencial importancia para estos estudios.
