Lagen Island, Locality Nd101, Palawan (Permian of Philippines)

Where: Philippines (11.1° N, 119.4° E: paleocoordinates 11.9° N, 119.4° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Minilog Formation, Roadian (272.3 - 268.8 Ma)

• Neoschwagerina craticulifera, Verbeekina verbeeki

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified wackestone and lithified packstone

• The fusulinid limestones represent low-energy open-shelf deposits. The fairly high diversity of the foraminifera and other biota points to an unconstrained water exchange with the open sea, whereas the absence of significant reworking indicates a low-energy environment.

•Occasional reworking of semi-lithified sediment is only evident in samples from southeastern Tapiutan Island (Nd 52, 53) where dark rounded clasts of fusulinid wackestones are embedded within a fight matrix of the same composition.

• Microfacies P1 (Fusulinid float-, wacke-, and packstone). This microfacies is characterized by abundant fusulinids associated with Climacammina and other smaller foraminifers floating in a micritic matrix rich in shell debris. When recrystallization and pressure solution are moderate, nearly all fusulinid tests are complete.

Size class: macrofossils
