dc.description.abstract | Although putative corals of uncertain affinities occur in the early Cambrian, the earliest definite tabulatecorals have not been described prior to the Early Ordovician in North America. This paper reports a new findingof a tabulate-like coralomorph forming part of biostratigraphically well-constrained reef mounds in the latestCambrian?Early Ordovician La Silla Formation in the Argentine Precordillera. The oldest record of the coralomorphgenus Amsassia is reported and a new species, A. argentina, is erected. The discovery of this genus in the lowermostOrdovician modifies the previously proposed paleogeographic distribution and patterns of origination and migrationroutes of this coral-like organism. Amsassia argentina n. sp. constitutes a main framework builder together with acomplex microbial consortium. This oldest occurrence of Amsassia as a reef builder represents a new record of askeletal organism in the gap of metazoan reef constructors after the demise of archaeocyaths in the late early Cambrian | |
