Their phylogenetic relationships are still poorly understood because their morphology is not always sufficient to infer their systematic position. Studies of phenotypical features, combined with cell wall ultrastructure, biogeochemistry and biomarkers may help to unravel their biological affinities. More precise placement within a geologic time
