Late Triassic (Carnian) corals from Timor-Leste (East Timor): their identity,setting, and biogeography

Four scleractinian coral taxa are described from limestones within a sandstone-shale séquence correlated with the Late Triassic Babulu Formation, Manatuto township, on the northern coast of Timor-Leste (East Timor). The coral fauna consists of three phaceloid taxa, Paravolzeia tìmorìca gen. et sp. nov., Craspedophyll ramosa sp. nov., Margarosmilia confluens (Münster), and a generically indeterminate solitary taxon attributed to the family Margarophylliidae. Ali four corals are related at various taxonomie levels to Carnian faunas from the Dolomites of northern Italy. Previously, only Norian coral faunas were known from the Triassic of Timor. The fauna exhibits both similarities to and differences from Carnian faunas of the Dolomites and helps confirm palaeogeographic affinities with the western Tethys, although during Late Triassic time Timor lay in the distant southeastern portai of the Tethys. Despite isolation from the western Tethys, the presence of two species foundalso in the Dolomites indicates that larvai dispersai occurred between the two areas.
