Eobalaenoptera harrisoni is an extinct species of baleen whale. The species was first described in June 2004 by researchers at the Virginia Museum of Natural History. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ... Phyla Porifera (sponges) Ctenophora (comb jellies) Cnidaria (coral, jellyfish, anenomes) Placozoa (trichoplax) Subregnum Bilateria (bilateral symmetry) Acoelomorpha (basal) Orthonectida (parasitic to flatworms, echinoderms, etc. ... Typical Classes Subphylum Urochordata - Tunicatas Ascidiacea Thaliacea Larvacea Subphylum Cephalochordata - Lancelets Subphylum Myxini - Hagfishes Subphylum Vertebrata - Vertebrates Petromyzontida - Lampreys Placodermi (extinct) Chondrichthyes - Cartilaginous fishes Acanthodii (extinct) Actinopterygii - Ray-finned fishes Actinistia - Coelacanths Dipnoi - Lungfishes Amphibia - Amphibians Reptilia - Reptiles Aves - Birds Mammalia - Mammals Chordates (phylum Chordata) include the vertebrates, together with... Orders Subclass Multituberculata (extinct) Plagiaulacida Cimolodonta Subclass Palaeoryctoides (extinct) Subclass Triconodonta (extinct) Subclass Eutheria (includes extinct ancestors)/Placentalia (excludes extinct ancestors) Afrosoricida Artiodactyla Carnivora Cetacea Chiroptera Cimolesta (extinct) Creodonta (extinct) Condylarthra (extinct) Dermoptera Desmostylia (extinct) Embrithopoda (extinct) Hyracoidea Insectivora Lagomorpha Litopterna (extinct) Macroscelidea Mesonychia (extinct) Notoungulata (extinct) Perissodactyla Pholidota Plesiadapiformes... Eutheria is a taxon (specifically, an infraclass) nearly synonymous with Placentalia, containing the placental mammals and the nearest ancestors of placental mammals (which are known only from the fossil record). ... Suborders Mysticeti Odontoceti (see text for families) The order Cetacea includes whales, dolphins and porpoises. ... Families Balaenidae Balaenopteridae Eschrichtiidae Neobalaenidae Scientifically known as the Mysticeti, the baleen whales, also called whalebone whales or great whales, form a suborder of the order cetacea. ... your mom goes to coloege LOL // Value of binomial nomenclature The value of the binomial nomenclature system derives primarily from its economy, its widespread use, and the stability of names it generally favors: Every species can be unambiguously identified with just two words. ... Families Balaenidae Balaenopteridae Eschrichtiidae Neobalaenidae Scientifically known as the Mysticeti, the baleen whales, also called whalebone whales or great whales, form a suborder of the order cetacea. ...

The researchers identified the species from a partial skeleton found in 1990 in Caroline County, Virginia, the site of a prehistoric ocean called the middle Miocene Calvert Formation of Virginia. The 11 m (35 ft) skeleton proved to have similar morphological characteristics to a clade of whales consisting of two modern taxonomic families - Balaenopteridae (the rorquals), and Eschrichtiidae (a family with one surviving species, the Gray Whale). Caroline County is a county located in the state of Virginia. ... A clade is group of organisms which share a common ancestor and which includes all decendents of that ancestor. ... Whales are the largest species of exclusively aquatic mammals, members of the order Cetacea, which also includes dolphins and porpoises. ...

The age of skeleton was estimated to be 14 million years, making the species the oldest known member of the clade by three to five million years. It also considerably narrowed the gap between the earliest known fossil record and estimated time of divergence of this clade from other baleen whales. Molecular studies have put this divergence time at around 25 million years.

The genus name Eobalaenoptera reflects the similarities between this skeleton and species in the genus Balaenoptera such as the Minke Whale; eo- is a prefix meaning ancient. The species is named after Carter Harrison, a volunteer worker at the museum. Binomial name Balaenoptera acutorostrata Lacepede, 1804 Binomial name Balaenoptera bonaerensis Burmeister, 1867 Minke Whale range Antarctic Minke Whale range Dwarf Minke Whale range The Minke Whale or Lesser Rorqual is a marine mammal belonging to the suborder of baleen whales. ...
