the textulariacea is a superfamily of middle jurassic to holocene agglutinated benthic textulariid foraminifera. tests are trochospiral, triserial, or biserial in early stages; later may be biserial or uniserial. walls are agglutinated, made of gathered material cemented together and are canaliculate - contain micro-tubular cavities extending between the inner and outer surfaces.
