Leptachatina fossilis Cooke in Hyatt & Pilsbry

Fossil Leptachatina Snail (Leptachatina fossilis)  

As its name implies, the Fossil Leptachatina Snail from the island of Kaua’I, Hawaiian Islands was already extinct when it was described in 1911.:  

The shell is umbilicate, conically ovate, white (in a fossil state) ….” [1]  

***

The shell was very small, reaching a height of only about 0,7 cm.  The Fossil Leptachatina Snail very likely was among the first snail species to disappear after the arrival of men.
