Resumen
Fossil woods of Lauraceae from the Ituzaingó Formation (Pliocene - Pleistocene), Paranáriver basin, Argentina. Six fossil woods with Lauraceae affinity from the fluvial sediments of the ItuzaingóFormation were described. The specimens were found in Hernandarias and Curtiembre fossiliferous localities,in Entre Ríos, Argentina. Combination of characters present in the specimens allowed us to distinguish theLauraceae from other dicotyledonous families and to assign them to two different fossil species: Laurinoxylonartabeae (Brea) Dupéron-Laudoueneix & Dupéron 2005 and a new genus. The Vulnerability Index (V) andMesomorphy Ratio (M) were calculated, and they indicated that the two species were adapted to wet environments.Comparison with the nearest living relatives suggests the existence of a flora linked to a watercourse, withriparian components.
