Porteiras, Missão Velha (Cretaceous to of Brazil)

Also known as Araripe Plateau, Chapada do Araripe

Where: Ceará, Brazil (7.3° S, 39.1° W: paleocoordinates 7.1° S, 6.5° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Missão Velha Formation (Vale do Carirí Group), Early/Lower Cretaceous to Early/Lower Cretaceous (145.0 - 113.0 Ma)

• 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.

• bed-level stratigraphic resolution

Environment/lithology: channel lag; sandstone

Size classes: macrofossils, mesofossils

Collected in 1988
