Santana do Cariri (general) (Cretaceous of Brazil)

Where: Ceará, Brazil (7.2° S, 39.7° W: paleocoordinates 12.5° S, 11.4° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Romualdo Member (Santana Formation), Early/Lower Albian (112.0 - 109.0 Ma)

• Santana Formation suggested to be early Albian in age by Heimhofer & Hochuli (2010) on the basis of palynomorphs

• member-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; concretionary, calcareous shale

• "lagoonal" (Kellner and Campos 2002); "The unit was deposited under quasi-marine conditions in the Araripe Basin, a large fault-bounded pull-apart basin that developed during the early stages of the opening of the Atlantic Ocean".
• fossils are from "limestone concretions embedded in shales" (Kellner and Campos 2002). "The Romualdo Member is a 4-30 m thick sequence of fissile, laminated black shales with numerous elliptical and sub-spherical concretions"

Size class: macrofossils

Preservation: concretion

Collection methods: quarrying, chemical,

• pterosaur is at the Museu de Ciencias da Terra/Departamento Nacional de Producao Mineral (DGM)

•SMNK: Staatliches Museum fuer Naturkunde, Karlsruhe, Germany
