Era (geology)

A geologic era is a subdivision of geologic time that divides an eon into smaller units of time. The Phanerozoic Eon is divided into three such time frames: the Paleozoic, Mesozoic, and Cenozoic represent the major stages in the macroscopic fossil record. These eras are separated by catastrophic extinction boundaries, the P-T boundary between the Paleozoic and the Mesozoic and the K-T boundary between the Mesozoic and the Cenozoic. There is evidence that catastrophic meteorite impacts played a role in demarcating the differences between the eras.

The Hadean, Archean and Proterozoic eons were as a whole formerly called the Precambrian. This covered the four billion years of Earth history prior to the appearance of hard-shelled animals. More recently, however, those eons have been subdivided into eras of their own.

Era (musical project)

Era (styled as +eRa+) is a new-age music project by French composer Eric Lévi. The band has sold more than 12 million albums. They use lyrics (by Guy Protheroe) which, although similar to Greek or Latin, are, in fact, deliberately devoid of any exact meaning.

They are best known for their singles "Ameno" and "Madona".

Style

Era mixes Gregorian chants and occasionally world music with contemporary electronic arrangements. It is reminiscent of new-age music projects such as Enigma, Gregorian, and Deep Forest. Lyrics are written in Pseudo-Latin and English, and some are based on beliefs of the 13th century French Christian Catholic Apostolic Roman, the Cathars.

Era's live shows and music videos often feature artists dressed in medieval or traditional clothes and armour. Usually, actors Pierre Bouisierie and Irene Bustamante perform at Era shows.

Language

Most Era songs are in Pseudo-Latin and others are in Latin.

They also have some songs in English such as "Mother" and "Looking For Something".

Geology (journal)

Geology is a publication of the Geological Society of America (GSA). The GSA claims that it is the most widely read scientific journal in the field of earth science. It is published monthly, with each issue containing 20 or more articles, and an annual total of 1166 pages.

One of the goals of the journal is to provide a forum for shorter articles and less focus on pure academic research type articles.
