TaxonomyCladistic analyses of fossils and extant balaenids place Balaenula as the sister taxon of right whales in a clade separate from the bowhead whale.[1][1] Fossil recordsThis genus is known in the fossil records from the Neogene to the Quaternary (age range: from 11.608 to 1.806 million years ago). Fossils are found in the marine strata of Italy, United Kingdom, United States, the Netherlands, France and Japan.[2][3][4] The most complete specimen known from the U.S.[5] (as well as the only one on display in North America[6]) was found at Lake Waccamaw, North Carolina in 2008. The whale's skull was excavated from the limestone outcropping by the state's Underwater Archaeology Branch, prepared, and permanently displayed at the Lake Waccamaw Depot Museum starting 2012.[7] SpeciesThere are two currently recognized species of Balaenula:[4]
An unnamed species from Japan (represented by a partial skeleton) is also known.[10] References1. ^Churchill, M., Berta, A. and Deméré, T.
