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
