Bermuda Land Snails
Poecilozonites
Bermuda land snails, scientific name Poecilozonites, are an endemic genus of pulmonate land snail in the family Gastrodontidae (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). 12 species are known from the fossil record, and 4 of these species (P. bermudensis, P. nelsoni, P. circumfirmatus, P. reinianus) survived into modern times, but due to the highly negative effects of human development, the extant species has been reduced down to only P. bermudensis and P. circumfirmatus.
Scientists believe that Poecilozonites colonised the mid-Atlantic island of Bermuda at least 300,000 years ago. Poecilozonites makes up 95% of Bermuda's terrestrial fossils. Only one other large pulmonate, Succinea, has been found as a fossil.
