Paleoenvironmental interpretation of late Quaternary molluscan assemblages from southern South América: A taphonomic comparison between the Strait of Magellan and the Beagle Channel

This study analyzes the Holocene molluscan assemblage in raised marine terraces along the coasts of the Strait of Magellan and the Beagle Channel. A total of 33 gastropods and 12 bivalves were identified. They constitute the first mollusk listing for deposits in the Strait of Magellan. Taphonomic an...
