In this study we report a new fossil locality found in the continental sediments of the Haro Formation. This formation is composed of palustrine, lacustrine and distal alluvial facies that represent the sedimentary filling of the west-central sector of the Ebro basin during the lower Miocene. In this paper we describe the vertebrate remains (fishes, lacertians, crocodiles, Turtles, glirids, cricetids and eomiids) found in the site of Bargota (Navarra). Based on the micromammals teeth study, the new fossil locality can be placed within the Agenian biozone Y
