Quantitative estimates of time-averaging in marine shell accumulations available to date are
limited primarily to aragonitic mollusk shells. We assessed time-averaging in Holocene …

The Río Turbio coal measures area, Austral Basin, is one of the few areas in Argentina that
records the Cretaceous/Paleogene and Paleocene/Eocene boundaries within a thick marine …

The variation in time-averaging between different types of marine skeletal accumulations
within a depositional system is not well understood. Here we provide quantitative data on …

Publisher Summary Studies on Late Cenozoic marine invertebrates recorded in Patagonia
have been performed since the nineteenth century. Mollusc shells—mostly gastropods and …

The analysis of the structure and evolutionary history of the Late Miocene marine molluscs
along the southwestern Atlantic littoral indicates that these faunas did not give rise to the …

Rhynchonelliform brachiopods were diverse and often dominant benthos of tropical seas in
the Paleozoic. In contrast, they are believed to be rare in open habitats of modern oceans …

The marine faunas from Patagonia, which are in need of a comprehensive revision, are
particularly important in the understanding of the origin and evolution of the marine biota in …

Abstract Over 14,000 specimens—5,204 brachiopods, 9,137 bivalves, and 178 gastropods—
acquired from 30 collecting stations (0 to 45 m depth) in the Ubatuba and Picinguaba bays …
