“…The lower Turonian rocks from the base of the recovered sequence were deposited within the warmest portion of the Late Cretaceous greenhouse climate, and deposition continued through to the early Campanian by which time Earth had cooled significantly (e.g., Huber et al, 2018;O'Connor et al, 2019). The sediments also span the time of expected initiation of seafloor spreading within the western to central portions of the Southern Rift System and are partially coeval with thick marine shales in the Otway Basin to the east (Gallagher et al, 2005). The high proportion of detrital material including terrestrial plant matter in a marine sequence could allow relationships between terrestrial and marine climate to be investigated.…”

“…The Australian Southern Rift System, in contrast, evolved from its epicontinental stage to an ocean basin by the end of the Paleogene. Maximum sedimentation rates in the offshore calcareous mudstones of the WIS generally do not exceed 25 m/myr in the basin center (e.g., Locklair and Sageman, 2008), whereas they exceed 120 m/myr in the carbonate-lean Turonian section of Site U1512 and were higher in other exploration wells on the southern Australian margin (e.g., Totterdell et al, 2000;Gallagher et al, 2005). Thus, any early Turonian Southern Interior Seaway (SIS) phase of the Southern Rift System was a deeper, darker, and more rapidly accumulating sibling, not a twin, of the WIS.…”

In this contribution we present the composition of the Late Cretaceous / Paleocene dinoflagellate cyst assemblages found in the Pelotas Basin, southern Brazil in order to provide a first paleobiogeographical comparison between this location, India and other former Gondwana continents: South America (Argentina and Uruguay), Africa (Nigeria and Western Ghana), Antarctica, Australia, and New Zealand. A total of 13 taxa, some endemic and other cosmopolitan were identified. The paleoenvironment of the Gondwana former members basins, as previously presented and attested by the dinoflagellate cysts are marginal marine nearshore, varying from neritic to shallow neritic and lagoonal or coastal swamps, which permitted the deposition of sediments in anoxic marine conditions. The present analysis of similarity between K/Pc dinoflagellate cyst associations allowed the establishment of paleobiogeographic distribution.
