This species has a small and left-handed (or sinistral) shell, as is always the case in this family. Physa mezzalirai dates from the Turonian to Santonian-aged Adamantina Formation (Upper Cretaceous Bauru Group), in São Paulo state, Brazil.[1] References1. ^1 2 Ghilardi,RP; Carbonaro, FA; & Simone, LRL. 2011.
