†Sloanea olmediaefolia has been described from many fossil leaves collected from lower Oligocene strata from 1857 to 1889 in Santa Giustina and Sassello in Central Liguria, Italy. Fossil leaves of this species have also been collected from the continental (fluvial and limnic) beds of the Csatka Formation near Oroszlány (western Hungary, northeastern Transdanubia); these beds are from the 34 million years old Oligocene regional stage Kiscellian.
