Coordinates: 15.3° North, 100.4° East (view map)
Paleocoordinates:28.1° South, 96.5° East
Basis of coordinate:estimated from map
Geographic resolution:small collection
Time
Period:Permian Epoch:Guadalupian
Stage:Wordian 10 m.y. bin:Permian 4
Key time interval:Wordian
Age range of interval:266.90000 - 264.28000 m.y. ago
Stratigraphy
Formation:Tak Fa
Stratigraphic resolution:bed
Stratigraphy comments: Yanagida (1964, 1988) reported the presence of the fusulinid Verbeekina verbeeki. However, Fontaine et al. (1994) suggested that the Tak Fa formation has a late Middle Permian (Murghabian) age based on bryozoans, brachiopods and the coral fauna. Verbeekina verbeeki Suggests a Wordian age.
