Eschrichtioides
''Eschrichtioides'' is an extinct genus of baleen whale known from the early Pliocene of northern Italy. Its type species, ''E. gastaldii'', had a complex taxonomic history, starting as a cetothere, then as an extinct member of ''Balaenoptera'', before being finally recognized as a relative of the gray whale. Distribution ''Eschrichtioides'' is one of two '' Eschrichtius'' relatives known from the Neogene of Italy, the other being '' Archaeschrichtius''. Its holotype, MRSN 13802, comes from the early Pliocene-age Sabbie d'Asti Formation of the Piedmont region in Italy. Classification Like other cetaceans from the Italian Pliocene, the classification of ''Eschrichtioides'' was highly contentious. described several species of ''Cetotherium'' from the Pliocene of northern Italy, including ''C. cortesi'' based on a specimen (MSRN 13802) found by Italian geologist Giuseppe Cortesi in 1816 near the town Cortandone (: paleocoordinates ) described how he, after a day of sear ...

Eschrichtiidae
Eschrichtiidae or the gray whales is a family of baleen whale (Parvorder Mysticeti) with a single extant species, the gray whale (''Eschrichtius robustus''), as well as three described fossil genera: '' Archaeschrichtius'' and ''Eschrichtioides'' from the Miocene and Pliocene of Italy respectively, and '' Gricetoides'' from the Pliocene of North Carolina. More recent phylogenetic studies have found this family to be invalid, with its members nesting inside the Balaenopteridae. The names of the extant genus and the family honours Danish zoologist Daniel Eschricht. Taxonomy In his morphological analysis, found that eschrichtiids and Cetotheriidae (''Cetotherium'', '' Mixocetus'' and '' Metopocetus'') form a monophyletic sister group of Balaenopteridae. A specimen from the Late Pliocene of northern Italy, named ''"Cetotherium" gastaldii'' by and renamed ''"Balaenoptera" gastaldii'' by , was identified as a basal eschrichtiid by who recombined it to '' Eschrichtioides gastal ...

Baleen Whale
Baleen whales (systematic name Mysticeti), also known as whalebone whales, are a parvorder of carnivorous marine mammals of the infraorder Cetacea (whales, dolphins and porpoises) which use keratinaceous baleen plates (or "whalebone") in their mouths to sieve planktonic creatures from the water. Mysticeti comprises the families Balaenidae (right and bowhead whales), Balaenopteridae (rorquals and the gray whale), and Cetotheriidae (the pygmy right whale). There are currently 16 species of baleen whales. While cetaceans were historically thought to have descended from mesonychids, molecular evidence instead supports them as a clade of even-toed ungulates (Artiodactyla). Baleen whales split from toothed whales (Odontoceti) around 34 million years ago. Baleen whales range in size from the and pygmy right whale to the and blue whale, the largest known animal to have ever existed. They are sexually dimorphic. Baleen whales can have streamlined or large bodies, depending on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cetotherium
''Cetotherium'' ("whale beast") is an extinct genus of baleen whales from the family Cetotheriidae. Taxonomy The family Cetotheriidae and the genus ''Cetotherium'' (sensu lato) have been used as wastebaskets for all kinds of baleen whales, most notably by , Spassky (1954) and . Based on more recent phylogenetic studies and revisions of many 19th century genera, much smaller monophyletic Cetotheriidae and ''Cetotherium'' sensu stricto is limited to a single or only a few species. For example, included only ''C. rathkii'' and ''C. riabinini'' in the genus and only ten genera in the family. Cetotheriidae were thought to have gone extinct during the Pliocene until 2012, when it was hypothesized that the pygmy right whale was the sole surviving species of this family. Formerly assigned to ''Cetotherium'' The following species were originally described as nominal species of ''Cetotherium'' but have been either reassigned to other genera or removed from ''Cetotherium'': * ''Cetot ...

Balaenoptera
''Balaenoptera'' () is a genus of rorquals containing eight extant species. ''Balaenoptera'' comprises all but two of the extant species in its family (the humpback whale and gray whale); the genus is currently polyphyletic, with the two aforementioned species being phylogenetically nested within it. This genus is known in the fossil records from the Neogene to the Quaternary (13.65 million years ago to the present). Taxonomy and systematics The genus ''Balaenoptera'' contains the following extant species and subspecies: * Common minke whale (''Balaenoptera acutorostrata'') ** North Atlantic minke whale (''Balaenoptera acutorostrata acutorostrata'') ** North Pacific minke whale (''Balaenoptera acutorostrata scammoni'') * Antarctic minke whale (''Balaenoptera bonaerensis'') * Sei whale (''Balaenoptera borealis'') ** Northern sei whale (''Balaenoptera borealis borealis'') ** Southern sei whale (''Balaenoptera borealis schlegelii'') * Bryde's whale (''Balaenoptera edeni'') ** ...

Fossil Taxa Described In 2008
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the abso ...

Bartolomeo Gastaldi
Bartolomeo Gastaldi (10 February 1818 – 5 January 1879) was an Italian geologist and palæontologist, and one of the founders of the Club Alpino Italiano. Gastaldi was born in Turin, then capital of the Kingdom of Sardinia. As a child he developed a passion for fossils; the finds he made during excursions in the areas around Turin and Asti were to form the basis for his extensive collection of fossils and geological specimens. Under pressure from his father he studied law at the University of Turin, Faculty of Law; after graduating in 1839 he entered the legal profession. On the death of his father in 1843 he abandoned his legal work and devoted his energies to geology and palaeontology, making field trips in various parts of Italy and in Spain. He spent the years 1849–52 in Paris taking courses at the Ecole des Mines, the Jardin des Plantes, the Collège de France and the Sorbonne. A particular interest was glaciology. Also at this time he first met Quintino Sella with whom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
