Hapettimena

Hapettimena is a genus of extinct land snails that lived during the Pliocene epoch. The name "Hapettimena" was first introduced by the malacologist George Washington sexes Robertson in 1925. Robertson described two species within this genus, which are characterized by distinctive external features of their shells.

Hapettimena shells are typically low-spired, tapering to a rounded apex. They have a thin parietal callus and a distinct ridged peristome. The type species, Hapettimena rotunda, was found in the United States, specifically in the southeastern states.

The exact classification and relationship of Hapettimena to other genera of land snails are not well established. Fossil remains of Hapettimena have been found in sedimentary rocks that date back to the Pliocene epoch, approximately 3-2 million years ago. The age of the fossils and the geographical distribution of their finds indicate that Hapettimena was likely native to the region now occupied by North America.

More research is needed to determine the evolutionary relationships between Hapettimena and other snail species. The fossil record of Hapettimena and other extinct genera of land snails has provided important insights into the geological and paleontological history of the Americas. As our understanding of these extinct species continues to evolve, so too will the insights they offer into the natural history of our planet.
