This study analyzes the Holocene molluscan assemblage in raised marine<br />terraces along the coasts of the Strait of Magellan and the Beagle<br />Channel. A total of 33 gastropods and 12 bivalves were identified. They<br />constitute the first mollusk listing for deposits in the Strait of<br />Magellan. Taphonomic analysis suggests a high energy environment with<br />epifaunal elements in the Strait of Magellan and a low energy<br />environment with the predominance of infaunal elements in the Beagle<br />Channel. All the collected species are living taxa suggesting that<br />postglacial climatic variations were not enough to alter the composition<br />of the communities since at least 6,000 yr BP in the southern<br />Chile-Argentina region.
