Lutetian
The Lutetian is, in the geologic timescale, a stage or age in the Eocene. It spans the time between . The Lutetian is preceded by the Ypresian and is followed by the Bartonian. Together with the Bartonian it is sometimes referred to as the Middle Eocene Subepoch. Stratigraphic definition The Lutetian was named after Lutetia, the Latin name for the city of Paris. The Lutetian Stage was introduced in scientific literature by French geologist Albert de Lapparent in 1883 and revised by A. Blondeau in 1981. The base of the Lutetian Stage is at the first appearance of the nanofossil ''Blackites inflatus'', according to an official reference profile (GSSP) established in 2011. Of two candidates located in Spain, the Gorrondatxe section was chosen.See thwebsite of Eustoquio Molinafor these candidates. The top of the Lutetian (the base of the Bartonian) is at the first appearance of calcareous nanoplankton species ''Reticulofenestra reticulata''. The Lutetian overlaps with the Geisel ...

Geologic Formations Of Nigeria
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Earth ...

List Of Fossil Sites
This list of fossil sites is a worldwide list of localities known well for the presence of fossils. Some entries in this list are notable for a single, unique find, while others are notable for the large number of fossils found there. Many of the entries in this list are considered Lagerstätten (sedimentary deposits that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues). Lagerstätten are indicated by a note () in the noteworthiness column. Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed. Such sites may have separate entries if they are considered to be more notable than the formation as a whole. In contrast, extensive formations associated with large areas m ...

Gigantornis
''Gigantornis eaglesomei'' is a very large prehistoric bird described from a fragmentary specimen from the Eocene of Nigeria. It was originally described as a representative of the albatross family, Diomedeidae, but was later referred to the pseudotooth or bony-toothed bird family, Pelagornithidae. ''Gigantornis'' is one of the largest pseudotooth birds, with an inferred wingspan of about 6 m (20 ft) it is among the largest birds ever. Its identified remains consist of a broken sternum found in Middle Eocene Ameki Formation deposits at Ameki (Nigeria). The fossil bird was considered to belong the albatross family (Diomedeidae), as no sterna of pseudotooth birds were known until its discovery, and it remained the only such specimen for decades. Only in the 1970s its true affinities were realized, after it had become clear that although it must have been from a dynamic soarer with wings like an albatross, it resembled pelicans ( order Ciconiiformes) rather than tubenos ...

Pappocetus
} ''Pappocetus'' is an extinct protocetid cetacean known from the Eocene of Nigeria and Togo. The type specimen BMNH M11414 an incomplete left mandible with symphysis, a deciduous premolar, and unerupted molars. It was found in Bartonian () layers of the Ameki Formation (, paleocoordinates ) in southern Nigeria. The specimen M11086 is a left mandibular ramus broken in three pieces with sockets for canines and incisors and the front part of a single-rooted P1. Andrews, to whom the two specimens were brought separately, noted that they "to some extent supplement one another, so that the structure is fairly clear" and thus estimated the size and morphology of the missing parts by comparing the specimens to each other. ''Pappocetus'' differs from all other known protocetid genera by the step-like notch on the ventral margin of the mandible below M2 and M3; from '' Indocetus'' and ''Rodhocetus'' by the deciduous double-rooted P1; from '' Protocetus'' and ''Babiacetus'' by the pre ...

Nsugbe Formation
Nsugbe is a town in Anambra East Local Government Area, Anambra State, Nigeria. Location It is bordered by Onitsha on the west, Nkwelle-Ezunaka, Umunya to the southwest, Anam to the North. On the east are towns such as Umuleri, Aguleri, Enugwu Aguleri, Nando, Nteje, Awkuzu, Igbariam, and Achalla. Among the villages within Nsugbe includes Agbalagbo, Amumu, Akpalagu and Oguari. Origin Oral tradition has it that the first settlers to arrive at Nsugbe were the descendants of Omini son of Enugwu Aguleri Eri who emigrated from Enugwu Aguleri after the death of their father and settled at Okpuno Enugwu Nsugbe, an area on the outskirt of modern Nsugbe. However, Nsugbe the leader of the group was recalled to Aguleri on the death of Enini (Omini) his father. Some of his descendants with his brother Nta remained and were later joined by other immigrants from Ivite Agulu-eri to establish the present day Enugwu Nsugbe, Offianta Nsugbe and Abah Nsugbe.

Bartonian
The Bartonian is, in the ICS's geologic time scale, a stage or age in the middle Eocene Epoch or Series. The Bartonian Age spans the time between . It is preceded by the Lutetian and is followed by the Priabonian Age. Stratigraphic definition The Bartonian Stage was introduced by Swiss stratigrapher Karl Mayer-Eymar in 1857. The name derives from the coastal village Barton-on-Sea (part of New Milton) in southern England. The Barton Group, a lithostratigraphic unit from the south English Hampshire Basin, is of Bartonian age. The distinction between group and stage was made in the second part of the 20th century, when stratigraphers saw the need to distinguish between litho- and chronostratigraphy. The base of the Bartonian is at the first appearance of the calcareous nanoplankton species ''Reticulofenestra reticulata''. In 2009, an official reference profile (GSSP) for the base of the Bartonian had not yet been established. The top of the Bartonian Stage (the base of the Pria ...

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...
