A distant traveller: a Late Jurassic nerineoid gastropod (Mollusca, Heterobranchia) on the Maasvlakte 2 beach, the Netherlands

A fragmentary nerineoid gastropod collected from the Maasvlakte 2 beach may be identified as Ptygmatis cf. bruntrutana (Thurmann, 1832). Probably originating from Upper Jurassic strata in north-eastern France, it must have been transported here by a forerunner of the River Meuse (Maas).
