The Australasian muricid gastropod Lepsiella as Pleistocene visitor to southernmost South America
Six shells belonging to a muricid gastropod species were recovered from a Pleistocene marine raised beach located on Navarino Island, in southern South America. None of the living species in the Beagle Channel or in the area is close, and none of the fossil species in the vicinity regions shows the...
