Plagiostomoceras is an orthocerid cephalopod from the lower Paleozoic (Upper Ordovician to Lower Devonian) of Europe and Australia.
Shells of Plagiostomoceras are long slender orthocones with circular to slightly depressed cross sections. Sutures are straight or slightly oblique and may have faint lateral lobes. The siphuncle is central or offset, probably ventrally. The aperture is strongly oblique, sloping adapically toward the presumed venter.
Plagiostomoceras is included in the Michelinoceratinae, a subfamily of the Orthoceratidae.
The ulna is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. It runs parallel to the radius, the other long bone in the forearm. The ulna is usually slightly longer than the radius, but the radius is thicker. Therefore the radius is considered to be the larger of the two.
The radius or radial bone is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. The ulna is usually slightly longer than the radius, but the radius is thicker. Therefore the radius is considered to be the larger of the two. It is a long bone, prism-shaped and slightly curved longitudinally.
The superior oblique muscle, or obliquus oculi superior, is a fusiform muscle originating in the upper, medial side of the orbit which abducts, depresses and internally rotates the eye. It is the only extraocular muscle innervated by the trochlear nerve.
In vertebrates, thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae. In humans, there are twelve thoracic vertebrae and they are intermediate in size between the cervical and lumbar vertebrae; they increase in size going towards the lumbar vertebrae, with the lower ones being a lot larger than the upper. They are distinguished by the presence of facets on the sides of the bodies for articulation with the heads of the ribs, as well as facets on the transverse processes of all, except the eleventh and twelfth, for articulation with the tubercles of the ribs. By convention, the human thoracic vertebrae are numbered T1–T12, with the first one (T1) located closest to the skull and the others going down the spine toward the lumbar region.
The obliquus capitis inferior muscle is the larger of the two oblique muscles of the neck. It arises from the apex of the spinous process of the axis and passes laterally and slightly upward, to be inserted into the lower and back part of the transverse process of the atlas.
Oblique type is a form of type that slants slightly to the right, used for the same purposes as italic type. Unlike italic type, however, it does not use different glyph shapes; it uses the same glyphs as roman type, except slanted. Oblique and italic type are technical terms to distinguish between the two ways of creating slanted font styles; oblique designs may be labelled italic by companies selling fonts or by computer programs. Oblique designs may also be called slanted or sloped roman styles. Oblique fonts, as supplied by a font designer, may be simply slanted, but this is often not the case: many have slight corrections made to them to give curves more consistent widths, so they retain the proportions of counters and the thick-and-thin quality of strokes from the regular design.
The abdominal internal oblique muscle, also internal oblique muscle or interior oblique, is an abdominal muscle in the abdominal wall that lies below the external oblique muscle and just above the transverse abdominal muscle.
The abdominal external oblique muscle is the largest and outermost of the three flat abdominal muscles of the lateral anterior abdomen.
Shamosaurus is an extinct genus of herbivorous basal ankylosaurid ankylosaur from Early Cretaceous deposits of Höövör, Mongolia.
The lower extremity of femur is the lower end of the femur in human and other animals, closer to the knee. It is larger than the upper extremity of femur, is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior; it consists of two oblong eminences known as the lateral condyle and medial condyle.
Nepenthes papuana is a tropical pitcher plant endemic to New Guinea. The specific epithet papuana is derived from Papua, an alternative name for the island.
The lower extremity of the humerus is flattened from before backward, and curved slightly forward; it ends below in a broad, articular surface, which is divided into two parts by a slight ridge.
The body or shaft of the humerus is almost cylindrical in the upper half of its extent, prismatic and flattened below, and has three borders and three surfaces.
The upper or proximal extremity of the humerus consists of the bone's large rounded head joined to the body by a constricted portion called the neck, and two eminences, the greater and lesser tubercles.
Parthenos sylvia, the clipper, is a species of nymphalid butterfly found in south and southeast Asia, mostly in forested areas. The clipper is a fast-flying butterfly and has a habit of flying with its wings flapping stiffly between the horizontal position and a few degrees below the horizontal. It may glide between spurts of flapping.
Appias lalage, the spot puffin, is a small butterfly of the family Pieridae, that is, the yellows and whites, which is found in India, Indochina and Hainan.
The blackspot shark is a small species of requiem shark in the family Carcharhinidae found in the tropical Indo-West Pacific Ocean between latitudes 24°N and 30°S, from the surface to a depth around 40 m (130 ft). Its length is a little under one meter (yard) and it is not considered to be dangerous to humans. It feeds mainly on fish, crustaceans, and squid. This shark is also caught in small-scale fisheries for human consumption.
Celaenorrhinus is a genus of skipper butterflies which are commonly termed sprites. An alternate name is flats, for their habit of holding their wings flat when resting, but this is also used for related genera. They belong to the spread-winged skipper subfamily (Pyrginae), and therein are the type genus of tribe Celaenorrhini.
Arhopala atrax, the dark broken-band oakblue or Indian oakblue, is a species of lycaenid or blue butterfly found in the Indomalayan realm.
Coelotrochus chathamensis is a species of small sea snail, a marine gastropod mollusc in the family Trochidae, the top snails or top shells.
