First report of Devonian bactritids (Cephalopoda) from South America: Paleobiogeographic and biostratigraphic implications

Devonian bactritids are described for the first time from South America. They come from siliciclastic rocks of the Talacasto Formation in the Precordillera Basin, west-central Argentina. The host strata span the Lochkovian - Emsian and contain other non-ammonoid cephalopods as well, thus refuting th...
