Temporal range: Pliocene
|Balaenula balaenopsis skeleton|
van Beneden, 1872
This 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.
The most complete specimen known from the U.S. (as well as the only one on display in North America) 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.
There are two currently recognized species of Balaenula:
- †Balaenula balaenopsis Van Beneden, 1872 (Type)
- †Balaenula astensis Trevisan, 1942 (from Italy)
Balaenula astensis was quite similar to the living right whale (Eubalaena glacialis) but much smaller, reaching a length of about 5 metres (16 ft). This ancient mysticete lived about four million years ago. Fossils have been found near Asti (Northern Italy), in a Zanclean/Piacenzian marine sandstone.
An unnamed species from Japan (represented by a partial skeleton) is also known.
