The Late Triassic of the back arc Domeyko Basin, Chile is characterized by the onset of
marine sedimentation that persisted throughout the rest of the Mesozoic. Carbonate bulk samples
from the Punta del Viento Limestone Formation have yielded a numerically small, but apparently
widespread, conodont fauna including Epigondolella mosheri, Epigondolella englandi and
Neogondolella steinbergensis. These specimens indicate a Rhaetian (Epigondolella mosheri conodont
Biozone roughly equivalent to the Paracochloceras amoenum ammonoid Biozone) age for this unit.
Their recovery represents the first record of conodonts from Chile, and also indicates a considerable
potential for use in correlating sequence stratigraphic events within the Mesozoic Marginal Sea in
Colombia, Peru and Chile.
