| Bajo Comisión - Kachaike Formation | Archangelsky S., Archangelsky A., et al (2012) | Kachaike | De las mismas muestras que estudiamos aquí se sugiere que la Fm. Kachaike, en Bajo Comisión, tiene una edad Albiana. Los quistes de dinoflagelados que se hallan en los puntos PBC 13-10 se atribuyen a la zona de intervalo australiana Muderongia tetracantha cuya edad mínima es Albiano temprano (Guler & Archangelsky, 2006). En cambio el polen de angiospermas de la parte media/superior del perfil sugiere una edad albiana tardía y quizás cenomaniana temprana en su parte cuspidal (Barreda & Archangels | "shale" | 112.03 - 93.5 Ma Cretaceous |
