Loma Gorda Formation
The Loma Gorda Formation (, Kl, Kslg) is a fossiliferous geological formation of the Upper Magdalena Valley (VSM) and surrounding Central and Eastern Ranges of the Colombian Andes, extending from Cundinamarca in the north to Huila and easternmost Tolima in the south. The uppermost unit of the Güagüaquí Group, a sequence of laminated siltstones and shales, dates to the Late Cretaceous period; Turonian to Coniacian epochs, and has a maximum thickness of . Etymology The formation was named in 1966 by De Porta, named Loma Gorda ("Fat Hill") in Ricaurte, Cundinamarca.Acosta & Ulloa, 2002, p.23 Description Lithologies The Loma Gorda Formation is characterised by laminated siltstones and shales with calcareous concretions.Acosta & Ulloa, 2002, p.24 The formation has provided fossils of '' Ankinatsytes venezolanus'', '' Barroisiceras onilahyense'', '' Codazziceras ospinae'', '' Eulophoceras jacobi'', ''Fagesia catinus'', '' Hauericeras madagascarensis'', '' Hoplitoides in ...

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. 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 t ...

Turonian
The Turonian is, in the International Commission on Stratigraphy, ICS' geologic timescale, the second age (geology), age in the Late Cretaceous epoch (geology), Epoch, or a stage (stratigraphy), stage in the Upper Cretaceous series (stratigraphy), Series. It spans the time between 93.9 ± 0.8 annum, Ma and 89.8 ± 1 Ma (million years ago). The Turonian is preceded by the Cenomanian Stage and underlies the Coniacian Stage. At the beginning of the Turonian an anoxic event, oceanic anoxic event (OAE 2) took place, also referred to as the Cenomanian-Turonian boundary event or the "Bonarelli Event". Sea level fall took place in the latter part of the Turonian from the highstand at the beginning of the Turonian. Stratigraphic definition The Turonian (French: ''Turonien'') was defined by the France, French paleontologist Alcide d'Orbigny (1802–1857) in 1842. Orbigny named it after the French city of Tours in the region of Touraine (department Indre-et-Loire), which is the original Typ ...

Cretaceous Africa
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . 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 largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic groups present in modern times can be ultimately traced back to origins in the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ammonites Of South America
Ammonoids are extinct, (typically) coiled-shelled cephalopods comprising the subclass Ammonoidea. They are more closely related to living octopuses, squid, and cuttlefish (which comprise the clade Coleoidea) than they are to nautiluses (family Nautilidae). The earliest ammonoids appeared during the Emsian stage of the Early Devonian (410.62 million years ago), with the last species vanishing during or soon after the Cretaceous–Paleogene extinction event (66 million years ago). They are often called ammonites, which is most frequently used for members of the order Ammonitida, the only remaining group of ammonoids from the Jurassic up until their extinction. Ammonoids exhibited considerable diversity over their evolutionary history, with over 10,000 species having been described. Ammonoids are excellent index fossils, and they have been frequently used to link rock layers in which a particular species or genus is found to specific geologic time periods. Their fossil shells usual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
