Crato Formation (Cretaceous of Brazil)

Where: Ceará, Brazil (7.1° S, 39.7° W: paleocoordinates 8.6° S, 8.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Sergipea variverrucata pollen zone, Crato Formation, Late/Upper Aptian (122.5 - 113.0 Ma)

• The age of the Crato Formation originally was considered to be Aptian to Albian (Doyle et al. 1982; Pons et al. 1990) and more recently was refined to the late Aptian (Doyle 1992; Pons et al. 1996). This was confirmed by Arai et al. (2001), who considered a Meso-Alagoas age for the Crato Formation, corresponding to the upper part of the Sergipea variverrucata (P-270) Palynozone and a Cytheridea(?) Ostracozone (NRT-011), which correlates to the late Aptian.

Environment/lithology: lacustrine - large; lithified, muddy mudstone

• The large Aptian-Albian paleolake might have covered an area of 7500 km2 (50 X 150 km). Successions of six different lakes have been discovered in which the limestones were deposited in shallow waters (Neumann et al. 2002). There is also evidence of marine ingressions during this time period.

Size class: macrofossils

Preservation: adpression, original cellulose, replaced with hematite

Reposited in the MfN

Collection methods: surface (in situ), mechanical,
