Historical faunal exchange between the Pontocaspian Basin and North America
Abstract Ecrobia is a genus of small brackish‐water mud snails with an amphi‐Atlantic distribution. Interestingly, the species occurring in the northwestern Atlantic, Ecrobia truncata , is more closely related to the Pontocaspian taxa, Ecrobia grimmi and Ecrobia maritima , than to the species occurr...

As for the direction of dispersal, the scientific data presented are not conclusive. However, there is clearly more support for the scenario of dispersal from the Pontocaspian Basin to North America than vice versa.

Abstract Ecrobia is a genus of small brackish‐water mud snails with an amphi‐Atlantic distribution.
