Revalotrypa is an extinct genus of bryozoan of the family Revalotrypidae that lived during the late Ordovician period.[1] It was initially placed within the order Trepostomatida, but later moved to Cystoporida, a classification supported by the discovery of the very similar genus Lynnopora, which possesses lunaria in its autozooidal apertures, a quality distinctive of Cystoporida.[2]
