Open publisher page 9 citations

Abstract

The acastomorph calmoniid trilobiteAndinacasteEldredge and Braniša, 1980, has been known from the basal Devonian (Lower Lochkovian) of Bolivia.Andinacaste espejensisn. sp., described from probable Lower Lochkovian strata of the Los Espejos Formation in the Precordillera of San Juan Province, is the first Argentine record of this genus. Accordingly,Andinacasteis identified as a typical component of basal Devonian trilobite assemblages over a broad geographic range in Andean South America.
