The Tournasian Age is one of the three ages in the Mississippian Epoch of the Carboniferous Period. It lasted from 359.2±2.5 million years ago to 345.4±2.1 million years ago. It was preceded by the Famennian Age and followed by the Visean Age. In the Tournaisian 'age' ancient forests formed and died making modern day Carbon based fuels; for example; coal; petrolium and other fossil fuels. Look up Age on Wiktionary, the free dictionary Age may refer to: The length of time that a person has lived, reckoned from date of birth in most cultures; see also: ageing, for the social, cultural, and economic factors of age and ageing. ...

RIGZONE - Saga Completes Well 102 on East Shaltinsky Field (553 words)
The new coring of the Tournaisian has given a more accurate redefinition of the level for water-oil contact from 1247.5 meters down to 1253 meters depth which increases the acreage of oil saturated pay zone from 24 km2 to approximately 54 km2.
The Tournaisian oil saturated pay zone is thereby extended and reaches into Saga's second oil field, the Petrovsky oil field on the south end of the licensed area.
Reserves of the Tournaisian pay zone are expected to increase accordingly with a minimum of 20%, the more exact increase of the resources will be determined after the interpretation of the 3D seismic.
Botany 2004 - Abstract Search (325 words)
Tournaisian time) are represented by a large number of detached seeds or cupulate structures and by more than 40 taxa corresponding to different types of anatomically preserved stems.
However emphasis is placed on the reinvestigation of Aporoxylon from Germany and on the description of new taxa from the Tournaisian of France and Algeria which all exhibit broad circular parenchymatous pith with over 40 sympodial xylem strands and dense secondary xylem but differing in leaf trace features.
Of particular interest, one new plant from France shows leaf traces, double in origin, and a petiole base of the Kalymma-type, therefore showing characteristics of calamopityalean seed ferns but being quite distinct in features of the stele, secondary xylem and phloem.
