The genus is known only from the Brazilian Paleocene deposits of the Itaboraí Basin, in the state of Rio de Janeiro.[2] The most characteristic feature of the genus is its apertural armature.[2] SpeciesThe sole species in the genus is Cortana carvalhoi (Brito,1967).[2] References1. ^Brito, I.M. 1967.
