Cortana is a fossil genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Bulimulidae. The genus is known only from the Brazilian Paleocene deposits of the Itaboraí Basin, in the state of Rio de Janeiro.[1] The most characteristic feature of the genus is its apertural armature.[1]


The sole species in the genus is Cortana carvalhoi (Brito,1967).[1]
