Formaçao Codó (Cretaceous of Brazil)

Where: Maranhão, Brazil (4.5° S, 44.0° W: paleocoordinates 6.1° S, 12.4° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Codó Formation, Late/Upper Aptian (122.5 - 113.0 Ma)

• formation-level stratigraphic resolution

Environment/lithology: terrestrial; lithified, muddy mudstone and lithified, silty siltstone

• Vários fósseis marinhos tem sido referidos, conforme pode ser visto na figura 2, para a Formação Codó. A própria seqüência sedimentar parece confirmar a influência marinha na deposição da unidade. Nas associações ora estudadas, contudo, elementos do microplâncton marinho parecem totalmente ausentes,

•com exceção de formas retrabalhadas do Devoniano. Evidentemente esta observação não objetiva negar categoricamente a existência de tal influência, já que os resultados apresentados são praticamente pontuais, não representando portanto,

•uma conclusão válida para toda a extensão da bacia.

• A Formação Codó compreende uma seqüência de folhelhos. calcários e evaporitos intercalados.

Size class: microfossils

• Other: Palynomorphs

Preservation: soft parts, original sporopollenin

Collection methods: bulk, chemical, hydrochloric, hydroflouric,
