Abstract

Early Pleistocene mollusks of the Tubul Formation are reviewed and 23 species are recognized. These are twelve bivalves, ten gastropods, and one scaphopod. With two exceptions, all of them are known from the Recent. The fauna is compared with Miocene, Pliocene-Pleistocene, and Recent faunas of the Chilean coast. The composition of the Tubul fauna resembles the Recent one of the Magellan Region, suggesting cooler water temperatures for south-central Chile during the early Pleistocene than at present.
