Bohaskaia monodontoides, a New Monodontid (Cetacea, Odontoceti, Delphinoidea) from the Pliocene of the Western North Atlantic Ocean
Here we describe Bohaskaia monodontoides, a new taxon of beluga-like odontocete cetacean from the early Pliocene Yorktown Formation of Virginia and North Carolina. Among odontocetes, Bohaskaia shares key characteristics of the rostrum and face with belugas (Delphinapterus leucas), narwhals (Monodon...
