Lithology description: A Formação Codó compreende uma seqüência de folhelhos. calcários e evaporitos intercalados.
Environment:terrestrial indet.
Geology comments: 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.
