Milioloidea
Milioloidea is one of five superfamilies belonging to the Miliolida,.
Milioloideans produce a coiled test, commonly with two, less frequently three or more, chambers per whorl arranged in varying planes about the longitudinal axis, which later may become involute or uncoil. Advanced forms may have secondary partitions within the chambers.
Species within the Milioloidea are found in Upper Triassic to recent marine sediments.
