Geography
Country:Brazil State/province:Ceará
Coordinates: 7.3° South, 39.1° West (view map)
Paleocoordinates:7.1° South, 6.5° West
Basis of coordinate:based on nearby landmark
Altitude:386 meters
Geographic resolution:small collection
Time
Period:Cretaceous Epoch:Early/Lower Cretaceous
Key time interval:Early/Lower Cretaceous - Aptian
Age range of interval:145.00000 - 100.50000 m.y. ago
Stratigraphy
Geological group:Vale do Carirí Formation:Missão Velha
Stratigraphic resolution:bed
Stratigraphy comments: Age is difficult to constrain sue to lack of diagnostic fossils and lack of horizons suitable for radiometric dating. The formation underlies the Crato formation, so is generally considered to be pre-Aptian in age.
