Glaucidium Kurochkini
Kurochkin's pygmy owl (''Glaucidium kurochkini'') is an extinct species of pygmy owl that existed in what is now California, U.S.A. during the Late Pleistocene Epoch. Discovery and naming The holotype of ''Glaucidium kurochkini'' is LACM RLB K9630, a left tarsometatarsus. The paratypes are left and right tarsometatarsi, LACM(CIT) 155031 and LACM(CIT) 155032, respectively. All three specimens come from the La Brea Tar Pits in Los Angeles, California. They all also persist to the Pit A in Bliss 29 of the area. Other possible specimens that are from the area but cannot be certainly assigned to ''G. kurochkini'' are K9631, a proximal left mandible; K9632, a complete right mandible; K9210, a complete right coracoid; G50, a complete left humerus; K9635, a proximal end of a right radius; K9404, a complete right carpometacarpus; K9350, a complete left femur; K984, a complete left tibiotarsus; and K9402, K9422, and K9423, all left tibiotarsi. Etymology ''G. kurochkini'' was named in 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Pleistocene
The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The Late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (formerly known as Middle Pleistocene) and succeeded by the officially ratified Greenlandian. The estimated beginning of the Tarantian is the start of the Eemian interglacial period (Marine Isotope Stage 5). It is held to end with the termination of the Younger Dryas, some 10th millennium BC, 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a provisional or "quasi-formal" designation by the International Union of Geological ...

Femur
The femur (; ), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia (shinbone) and patella (kneecap), forming the knee joint. By most measures the two (left and right) femurs are the strongest bones of the body, and in humans, the largest and thickest. Structure The femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. Human females have thicker pelvic bones, causing their femora to converge more than in males. In the condition ''genu valgum'' (knock knee) the femurs converge so much that the knees touch one another. The opposite extreme is ''genu varum'' (bow-leggedness). In the general populatio ...

Pleistocene Birds Of North America
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

Oraristrix
The La Brea owl (''Oraristix brea'') is an extinct owl reported from the upper Pleistocene asphalt deposits of the La Brea Tar Pits in Los Angeles, California. It was first described in 1933 by Hildegarde Howard as ''Strix brea'', but this extinct owl was recently placed into its own genus by Campbell and Bocheński (2010). The Brea owl has also been found in the upper Pleistocene asphalt deposits of Carpinteria, California. ''Oraristrix brea'' is interpreted as more terrestrial in habits than forest owls because, compared to North American species of ''Bubo'' and ''Strix'', it had longer legs relative to its wingspan.

Trochlea Metatarsi
Trochlea (Latin for pulley) is a term in anatomy. It refers to a grooved structure reminiscent of a pulley's wheel. Related to joints Most commonly, trochleae bear the articular surface of saddle and other joints: * Trochlea of humerus (part of the elbow hinge joint with the ulna) * Trochlea of femur (forming the knee hinge joint with the patella) * The trochlea tali in the superior surface of the body of talus (part of the ankle hinge joint with the tibia) * Trochlear process of the calcaneus * In quadrupeds, the trochlea of Radius (bone) * The "knuckles" of the tarsometatarsus which articulate with the proximal phalanges in a bird's foot Related to muscles It also can refer to structures which serve as a guide for muscles: * Trochlea of superior oblique (see also superior oblique muscle), a mover of the eye which is supplied by the trochlear nerve The trochlear nerve (), ( lit. ''pulley-like'' nerve) also known as the fourth cranial nerve, cranial nerve IV, or CN IV, is a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulcus (morphology)
In biological morphology and anatomy, a sulcus (pl. ''sulci'') is a furrow or fissure (Latin ''fissura'', plural ''fissurae''). It may be a groove, natural division, deep furrow, elongated cleft, or tear in the surface of a limb or an organ, most notably on the surface of the brain, but also in the lungs, certain muscles (including the heart), as well as in bones, and elsewhere. Many sulci are the product of a surface fold or junction, such as in the gums, where they fold around the neck of the tooth. In invertebrate zoology, a sulcus is a fold, groove, or boundary, especially at the edges of sclerites or between segments. In pollen a grain that is grooved by a sulcus is termed sulcate. Examples in anatomy Liver *Ligamentum teres hepatis fissure *Ligamentum venosum fissure *Portal fissure, found in the under-surface of the liver *Transverse fissure of liver, found in the lower surface of the liver *Umbilical fissure, found in front of the liver Lung *Azygos fissure, of ri ...

Posterior (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek language, Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axis, anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aegolius
''Aegolius'' is a genus of small true owls. The genus name is from Latin, ''aegolius'', is a type of screech owl that was thought to be a bird of ill omen. Taxonomy The genus ''Aegolius'' was introduced in 1829 by the German naturalist Johann Jakob Kaup with the boreal owl (''Aegolius funereus'') as the type species. The genus name is Latin for a screech owl, the word came from the Ancient Greek ''aigōlios'' meaning "a bird of ill omen". In Greek mythology, Aegolius (mythology), Aegolius was originally a man whom Zeus transformed into an owl. Species The genus contains five species: * Boreal owl or Tengmalm's owl, ''Aegolius funereus'' * Northern saw-whet owl, ''Aegolius acadicus'' *† Bermuda saw-whet owl, ''Aegolius gradyi'' (extinct) * Unspotted saw-whet owl, ''Aegolius ridgwayi'' * Buff-fronted owl, ''Aegolius harrisii'' Description ''Aegolius'' owls are small, stout, short-tailed, and broad-winged, with large, round facial discs.
