The study of the interaction of cicatricose spores related to the family Anemiaceae with other botanical groups in the palynological record contributes to a better understanding of the paleoecological, paleoclimatic and paleoenvironmental aspects of this family through geological times. The present work based on the investigation of Anemiaceae fossil spores and other contemporary palynomorphs in different geological rock units and time windows from Brazil, France and India. For the purpose to fulfill the objectives of this study, detailed statistical analyses are applied in order to trace the adaptation of Anemiaceae in variable conditions throughout its geological existence, especially that this family is distributed spatially through a large regional scale of the world and was not limited to warm and humid paleoclimates. Results show that fossil Anemiaceae has been survived interacting among a diverse community of plants in a wide spectrum of paleoenvironments and paleoclimates.
