Aipe
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.

Euomphaloceratinae
Euomphaloceratinae is a subfamily of Upper Cretaceous ammonites included in the Acanthoceratidae, characterized by generally evolute shells with quadrate whorl sections that are strongly ribbed. Sutures are ammonitic, but not overly complex. Genera include: *'' Burroceras'' *'' Codazziceras'' *''Euomphaloceras'', (type genus) *'' Hourcqiceras'' *''Kamerunoceras'' *'' Lotzeites'' *''Morrowites'' *'' Paraburroceras'' *'' Paramammites'' *'' Pseudaspidoceras'' *''Romaniceras'' *'' Shuparoceras'' some of which have been removed from other taxa where originally placed. ''Euomphaloceras'', the type genus of the subfamily, was removed from the Acanthoceratinae sensu Arkell et al. 1957, ''Kamarunoceras'' and ''Pseuaspidoceras'' from the Mammitinae, sensu Arkell et al. 1957. Others were added since initial publication of the Treatise on Invertebrate Paleontology The ''Treatise on Invertebrate Paleontology'' (or ''TIP'') published by the Geological Society of America and the Universit ...

Cretaceous Colombia
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by t ...

Ammonites Of South America
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.

Acanthoceratidae
Acanthoceratidae is an extinct family of acanthoceratoid cephalopods in the order Ammonitida, known from the Upper Cretaceous. The type genus is '' Acanthoceras''. Diagnosis Acanthoceratidae species are strongly tuberculate with at least umbilical and ventrolateral tubercles in most genera included. Ribs are dominant in some, in others weak or absent on the outer whorls. Most are evolute, compressed to very depressed in section. Sutures are ammonitic with little variation, but showing a tendency for simplication in later genera. Taxonomy Acanthoceratidae de Grossouvre, 1894 includes the following subfamilies. * Acanthoceratinae de Groussouvre, 1894 *Euomphaloceratinae Euomphaloceratinae is a subfamily of Upper Cretaceous ammonites included in the Acanthoceratidae, characterized by generally evolute shells with quadrate whorl sections that are strongly ribbed.

Ammonitida Genera
Ammonitida is an order of ammonoid cephalopods that lived from the Jurassic through Paleocene time periods, commonly with intricate ammonitic sutures. Ammonitida is divided into four suborders, the Phylloceratina, Lytoceratina, Ancyloceratina, and Ammonitina. The Phylloceratina is the ancestral stock, derived from the Ceratitida near the end of the Triassic. The Phylloceratina gave rise to the Lytoceratina near the beginning of the Jurassic which in turn gave rise to the highly specialized Ancyloceratina near the end of the Jurassic. Both the Phylloceratina and Lytoceratina gave rise to various stocks combined in the Ammonitina. These four suborders are further divided into different stocks, comprising various families combined into superfamilies. Some like the Hildoceratoidea and Stephanoceratoidea are restricted to the Jurassic. Others like the Hoplitoidea and Acanthoceratoidea are known only from the Cretaceous. Still others like the Perisphinctoidea Perisphinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agustín Codazzi
Giovanni Battista Agostino Codazzi (alternatively known in Latin America as Agustín Codazzi; 12 July 1793 – 7 February 1859) was an Italo-Venezuelan soldier, scientist, geographer, cartographer, and governor of Barinas (1846–1847). He made his main investigations and cartographic work in Venezuela and Colombia, thereby creating for both countries a complete set of maps and statistics after the tumultuous years following independence from the Spanish Empire. Biography Codazzi was born in the Italian city of Lugo. Since young he appreciated the ideals of the French Revolution and, after his studies at the military academy "Scuola di Artiglieria" of Pavia, actively served in the Napoleon Army. With the defeat of Napoleon in 1815 Codazzi moved away from Italy and after some travels went to Venezuela, where he offered his military knowledge to Simon Bolivar. Successively he received the task of mapping the area of the Maracaibo Lake and the borders between Venezu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
