Pelecanoides Miokuaka
''Pelecanoides miokuaka'' is an extinct species of diving petrel of New Zealand. Described in 2007, it is known only from a single humerus bone that was discovered from early Miocene sediments of the Manuherikia Group. Taxonomy The bone, a humerus, was discovered in a cliff at Mata Creek, in Otago, New Zealand. It was collected on 5 September 2002 by Trevor Worthy and Alan Tennyson. This location represents early Miocene (19–16 mya) sediments of the Manuherikia Group. Several characteristics of the bone identify it as a diving petrel: the flattened shaft, the proximal origin of the dorsal condyle, the short and blunt supracondylaris process, the shallow ''fossa m. brachialis'', and the elongated ''epicondylaris venralis''. The species epithet ''miokuaka'' combines the words "miocene" and ''kuaka'', the Maori word for diving petrels. It has been given the common name of Miocene diving petrel. Description The humerus has a maximum distal width (through the condyles) of 6. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diving Petrel
The diving petrels form a genus, ''Pelecanoides'', of seabirds in the family Procellariidae. There are four very similar species of diving petrels, distinguished only by small differences in the coloration of their plumage, habitat, and bill construction. They are only found in the southern hemisphere. The diving petrels were formerly placed in their own family, the Pelecanoididae. Diving petrels are auk-like small petrels of the southern oceans. The resemblances with the auks are due to convergent evolution, since both families feed by pursuit diving, although some researchers have in the past suggested that the similarities are due to relatedness. Among the Procellariiformes the diving petrels are the family most adapted to life in the sea rather than flying over it, and are generally found closer inshore than other families in the order. Taxonomy The genus ''Pelecanoides'' was introduced in 1799 by the French naturalist Bernard Germain de Lacépède for the common diving ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested part ...

Miocene Birds
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Birds Of New Zealand
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossa (anatomy)
In anatomy, a fossa (; plural ''fossae'' ( or ); from Latin ''fossa'', "ditch" or "trench") is a depression or hollow, usually in a bone, such as the hypophyseal fossa (the depression in the sphenoid bone).Venieratos D, Anagnostopoulou S, Garidou A., A new morphometric method for the sella turcica and the hypophyseal fossa and its clinical relevance.;Folia Morphol (Warsz). 2005 Nov;64(4):240-7. Some examples include: In the Skull: * Cranial fossa ** Anterior cranial fossa ** Middle cranial fossa *** Interpeduncular fossa ** Posterior cranial fossa * Hypophyseal fossa * Temporal bone fossa ** Mandibular fossa ** Jugular fossa * Infratemporal fossa * Pterygopalatine fossa * Pterygoid fossa * Lacrimal fossa ** Fossa for lacrimal gland ** Fossa for lacrimal sac * Mandibular fossa * Scaphoid fossa * Jugular fossa * Condyloid fossa * Rhomboid fossa In the Mandible: * Retromolar fossa In the Torso: * Fossa ovalis (heart) * Infraclavicular fossa * Pyriform fossa * S ...

Common Diving Petrel
The common diving petrel (''Pelecanoides urinatrix''), also known as the smaller diving petrel or simply the diving petrel, is a diving petrel, one of four very similar auk-like small petrels of the southern oceans. It is native to South Atlantic islands and islands of the subantarctic southern Indian Ocean, islands and islets off New Zealand and south-eastern Australian islands. Taxonomy The common diving petrel was formally described in 1788 by the German naturalist Johann Friedrich Gmelin. He placed it with the other petrels in the genus ''Procellaria'' and coined the binomial name ''Procellaria uriatrix''. Gmelin based his description on the "diving petrel" that had been described in 1785 by the English ornithologist John Latham in the second volume of his ''A General Synopsis of Birds''. Latham reported that they were found in great numbers in Queen Charlotte Sound at the northern end of South Island, New Zealand. The common diving petrel is now one of four petrels p ...

South Georgia Diving Petrel
The South Georgia diving petrel or Georgian diving-petrel (''Pelecanoides georgicus'') is one of five very similar small auk-like diving petrels of the southern oceans. It is native to the South Atlantic and islands of the southern Indian Ocean and south-eastern Australia. Taxonomy and nomenclature The American ornithologist Robert Cushman Murphy and the zoologist Francis Harper described the South Georgia diving petrel in 1916. Its specific name, ''georgicus,'' is derived from the South Georgia islands where they identified the species. Other common names include ''puffinure de Géorgie du Sud'' (French), ''Breitschnabel Lummensturmvogel'' (German), and ''potoyunco de Georgia'' (Spanish). A unique New Zealand population is now considered a separate species, the Whenua Hou diving petrel. Description The South Georgia diving petrel is a small, plump petrel, in length and weighing around . Its plumage is black above and dull white below, and it has a stubby black bill with pa ...

Māori Language
Māori (), or ('the Māori language'), also known as ('the language'), is an Eastern Polynesian language spoken by the Māori people, the indigenous population of mainland New Zealand. Closely related to Cook Islands Māori, Tuamotuan, and Tahitian, it gained recognition as one of New Zealand's official languages in 1987. The number of speakers of the language has declined sharply since 1945, but a Māori-language revitalisation effort has slowed the decline. The 2018 New Zealand census reported that about 186,000 people, or 4.0% of the New Zealand population, could hold a conversation in Māori about everyday things. , 55% of Māori adults reported some knowledge of the language; of these, 64% use Māori at home and around 50,000 people can speak the language "very well" or "well". The Māori language did not have an indigenous writing system. Missionaries arriving from about 1814, such as Thomas Kendall, learned to speak Māori, and introduced the Latin alphabet. In 1 ...

Humerus
The humerus (; ) is a long bone in the arm that runs from the shoulder to the elbow. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections. The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body is cylindrical in its upper portion, and more prismatic below. The lower extremity consists of 2 epicondyles, 2 processes ( trochlea & capitulum), and 3 fossae ( radial fossa, coronoid fossa, and olecranon fossa). As well as its true anatomical neck, the constriction below the greater and lesser tubercles of the humerus is referred to as its surgical neck due to its tendency to fracture, thus often becoming the focus of surgeons. Etymology The word "humerus" is derived from la, humerus, umerus meaning upper arm, shoulder, and is linguistically related to Gothic ''ams'' shoulder and Greek ''ōmos''.

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term fo ...
