Trace fossils have been used worldwide to access paleoecologic data in sedimentary sections. In Parana Basin (southern Brazil), trace fossils are stratigraphically well distributed; however, they are understudied if compared to body macrofossils or ...

Abstract The Early-Middle Llandoverian was similar to the end of the Late Ordovician in the general features of palaeogeography and biotas. In the southern hemisphere, Gondwana was still integral, except for a number of small separate plates along its margins, and it was situated mostly in the middle and high latitudes south to 30°S ...

The relationship of the Yangtze Block with other continental blocks of the Rodinia and Gondwana supercontinents is hotly debated. Here we report U–Pb and Lu–Hf isotopic data for zircons from the latest Neoproterozoic Yanjing Group and the overlying ...

Abstract Silurian biogeography is characterized by a globally moderate climatic gradient, on which is superimposed a low latitude, warm region, moderate level of longitudinal provincialism. The cool to cold region Malvinokaffric Realm is bounded to the north by the warm water North Silurian Realm.
