The end-Triassic mass extinction (c. 200 Mya) was the most severe biotic crisis experienced by modern marine invertebrate faunas. Although diversity patterns are increasingly well known, the ecological response after the mass extinction in marine habitats is less clear. New paleoecological data from two widely separated and stratigraphically expanded Lower Jurassic successions (Nevada, USA and Central Andes, Peru) demonstrate complete ecological restructuring of benthic marine habitats that lasted approximately two million years after the mass extinction. At both sites, Late Triassic carbonate systems are replaced by siliceous sponge-dominated ecosystems in the Early Jurassic. The ¿sponge takeover¿ was likely facilitated by a unique confluence of circumstances: extinction-driven changes in benthic ecology coupled with increased global silica flux (a limiting nutrient for sponges) from weathering of the massive Central Atlantic Magmatic Province (CAMP). We study ocurrences in Peru in comparisson to those in USA (Nevada) to stablish the characteristics of such an event that results not only in global mass extinction, but profound ecological restructuring lasting millions of years
