New Insertae Sedis Genus Angelucysta from the Lower Carboniferous Dinantian of Iraq

A distinctive form of insertae sedis cyst is described in detail from samples of Ora, Harur Formations and Unit A in boreholes Kh5/1 and Khleisia-1. It constitute the monotypic base for new genus Angelucysta (type species A mosuliana). The form is associated with spore suite that is clearly representative of Early Carboniferous (Dinantian), so that it is considered as an index fossil for this age.
