Aipe River
Aipe is a town and municipality in the Huila Department, Colombia. It is located on the west bank of the Magdalena River in the Central Ranges of the Colombian Andes at altitudes between . Aipe borders Natagaima, Ataco and Planadas of the department of Tolima in the north and west, Villavieja and Tello in the east, and the departmental capital Neiva in the south. History In early 1741, Doña Teresa and Don Enríque Cortés, descendants of Mr. Jacinto Cortés, gave 80 hectares to establish a new town, and are considered the founders of the Aipe. In 1770, the church hierarchy and government in Neiva records the construction of the church of Our Lady of Sorrows. In 1874, Aipe acquired autonomy from Neiva, as a member of the canton district of Villavieja and on 8 April 1912 by Ordinance No. 26, was created as a municipality by the Departmental Assembly. Geography The municipality of Aipe is located on the left bank of the Magdalena River. It is located in the northwest of the ...

Municipalities Of Colombia
The Municipalities of Colombia are decentralized subdivisions of the Republic of Colombia. Municipalities make up most of the departments of Colombia with 1,122 municipalities ('' municipios''). Each one of them is led by a mayor (''alcalde'') elected by popular vote and represents the maximum executive government official at a municipality level under the mandate of the governor of their department which is a representative of all municipalities in the department; municipalities are grouped to form departments. The municipalities of Colombia are also grouped in an association called the ''Federación Colombiana de Municipios'' (Colombian Federation of Municipalities), which functions as a union under the private law and under the constitutional right to free association to defend their common interests.

Morrowites
''Morrowites'', named by Cobban and Hook, 1983, is a moderate to large-sized ammonite with quadrangular to depressed whorls, broadly rounded to depressed venter, low ribs, umbilical and inner and outer ventrolateral tubercles and smooth early whorls except for occasional ribs along weak constrictions. The suture is moderately simple and has an unusually broad bifid first lateral lobe. It is so far restricted to the Lower Turonian stage, in the mid Cretaceous. ''Morrowites'' closely resembles ''Mammites'', however ''Morrowites'' has a broad first lateral lobe, ''Mammites'' has a narrow one. The very early whorls of ''Morrowites'' are smooth except for distantly placed ribs and constrictions, those of ''Mammites'' have normal ribs and tubercles. Etymology ''Morrowites'' is named in honor of A. L. Morrow who made a pioneering study of Cenomanian and Turonian ammonites of Kansas. Distribution Fossils of ''Morrowites'' have been found in Colombia ( Loma Gorda Formation, Aipe, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neoptychites
''Neoptychites'' is an extinct ammonoid cephalopod genus from the Turonian stage of the Upper Cretaceous (around 94 to 89 Ma), with a worldwide distribution. Description Neoptychites includes extremely involute Ammonitida whose outer whorls have a high triangular section with a moderately rounded venter (the outer rim). Tho body chamber in adults is generally smooth, with a constricted aperture. The earliest whorls are smooth except for periodic constrictions; later juvenile whorls have numerous low ribs without tubercles. Taxonomy ''Neoptychites'' belongs to the ammonite family Vascoceratidae and is included in the subfamily Vasoceratinae. The genus was named by Kossmat in 1895. Its type species is ''Ammonites telinga'' Stoliczka, 1865 (= ''Ammonites cephalotus'' Courtiller, 1860). It is probably derived from '' Paravascoceras''. Distribution Fossils of ''Neoptychites'' have been found in Austria, Brazil, Cameroon, Colombia ( La Frontera (Huila, Cundinamarca, Boyacá) ...

Fagesia
''Fagesia'' is a small, subglobular ammonite (suborder Ammonitina) belonging to the vascoceratid family of the Acanthocerataceae that lived during the Turonian stage of the Late Cretaceous, 92-88 Ma ago. The shell of ''Fagesia'' is about 9.5 cm (3.47 in) in diameter, typically with blunt umbilical tubercles from which spring 2 or three ribs each, but which are lost in the late growth stage. The suture is ammonitic with long spikey lobes and saddles with rounded subelements.

Acanthoceras (ammonite)
''Acanthoceras'' is an extinct cephalopod genus belonging to the subclass Ammonoidea and family Acanthoceratidae that lived from the Albian to early Coniacian stages of the Cretaceous.''Acanthoceras'' at .org Description Their shells had ornate ribs whose function is unknown, although some scientists have speculated that these ribs helped strengthen the animals' shells to allow them to live at greater depths where the water pressure is higher.

Ammonite
Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids such as the living ''Nautilus'' species. The earliest ammonites appeared during the Devonian, with the last species vanishing during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and linking the rock layer in which a particular species or genus is found to specific geologic time periods is often possible. Their fossil shells usually take the form of planispirals, although some helically spiraled and nonspiraled forms (known as heteromorphs) have been found. The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns.

Coniacian
The Coniacian is an age or stage in the geologic timescale. It is a subdivision of the Late Cretaceous Epoch or Upper Cretaceous Series and spans the time between 89.8 ± 1 Ma and 86.3 ± 0.7 Ma (million years ago). The Coniacian is preceded by the Turonian and followed by the Santonian. Stratigraphic definitions The Coniacian is named after the city of Cognac in the French region of Saintonge. It was first defined by French geologist Henri Coquand in 1857. The base of the Coniacian Stage is at the first appearance of the inoceramid bivalve species '' Cremnoceramus deformis erectus''. The official reference profile for the base (a GSSP) is located in Salzgitter-Salder, Lower Saxony, Germany. The top of the Coniacian (the base of the Santonian Stage) is defined by the appearance of the inoceramid bivalve '' Cladoceramus undulatoplicatus''. The Coniacian overlaps the regional Emscherian Stage of Germany, which is roughly coeval with the Coniacian and Santonian Stages. In ...

Cenomanian
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for ...
