The Mamu Formation around Ozalla has been palynologically examined from surface outcrop, 44 Palynoflora species were recorded and Late Maastrichtian to early Eocene age has been assigned. Mangrove swamp to fresh water swamp paleoenvironments is inferred based on the Palynofacies, Inaperturopollonites sp., Spinizonocolprite baculates, Longapertites, Tricolporopolenites sp., Proxpertites cursus, Diporites sp., Monocolpites margninatus,  Monoulcites sp., Tricolpites sp., Leiotriletes adrennis, Bombacacildites sp, and Ctenoloplophonidites costatus. A mean annual precipitation of 1003 to 1520 mm which indicate a moist tropical climate condition predominating over the study area.
