Among siliciclastic deposits in the Wailuli Valley of Timor Leste are cyclic marine sand-shale units, attributed to the Cribas Formation, that yield terrestrial palynomorphs, including a diverse Dulhuntyispora assemblage. The palynomorph assemblage belongs in the D. parvithola Spore-Pollen Zone suggesting a Late Permian age (late Guadalupian to early Lopingian). Recovered foraminifers support the Permian age. This is the first published documentation of a definitive northeastern Gondwanan Permian spore-pollen assemblage from Timor. The land-plant derived assemblages place Timor proximal to the Bonaparte Basin during the Capitanian to Wuchiapingian. The occurrence suggests that the Cribas Formation in Timor is, at least in part, equivalent to the Cape Hay Formation of the Bonaparte Basin of northwestern Australia.
