Collectors in south Florida tend to get all worked up over finding Jenneria specimens, so I figured I would display one from the Aquitanian Miocene of southwestern France (length = 16 mm). The species is apparently fairly common at some sites, while rare everywhere else (shells generally aren’t truly rare when found in their naturally preferred environment, after all). It is believed to have preferred a coral reef environment.
