Taphonomy and Paleoecology of Villamil Fossil Megagastropods of Isla Isabela

  • Sally E. Walker
Part of the Topics in Geobiology book series (TGBI, volume 8)


The study of Galápagos molluscan fossils has chiefly been one of documenting the systematics, biogeographic affinities, and distribution of the fauna. In conjunction with radiometric age dating, these fossils have also provided evidence for the geological youth of the islands, thereby setting the evolutionary time scale for this insular fauna (Dall and Ochsner, 1928; Hertlein, 1972; Emerson, 1978; James, 1984; Hickman and Lipps, 1985; Taviani, 1979).
