Abstract From the upper Maastrichtian (Tarbur Fm.) and Paleocene of Iran, 20 species scleractinian corals belonging to 17 genera 14 families, one octocoral Heliopora are newly recorded. Furthermore, coral previously described from Tarbur Fm. revised included in evaluation, resulting a total 37 28 families (including 3 subfamilies) for Iranian K/Pg-boundary time period. The majority taxa (21 out...

Palynology is an important tool for establishing age and interpreting paleoenvironments in both continental marine deposits. This paper provides a summarized overview of the palynological information published deposits Colombia ranging from Paleozoic to Miocene-Pliocene. We found 111 publications indexed journals contain data 511 sections or wells. has been mainly studied Eastern Llanos; Triass...

The state of Rio Grande do Sul (RS) is located in the extreme south Brazil, within a transition region between tropical and subtropical zones South America that has been frequently affected by fluctuations climate vegetation over last millennia. Palynomorphs preserved sediments have provided excellent study material for paleoenvironmental reconstitutions this region, as they reveal source organ...

We describe a water fern spore assemblage from the Maastrichtian La Colonia Formation, Chubut Province, Patagonia, Argentina. The includes three species of Azolla (A. andreisii sp. nov., A. coloniensis, and 1), two Azollopsis intermedia tomentosa), Crybelosporites pannuceus, Gabonisporis cristata, Ghoshispora sp., Grapnelispora loncochensis, Molaspora (M. lobata M. reticulata), Paleoazolla pata...

The continental early-middle Miocene Santa Cruz Formation (SCF) in Austral Patagonia contains the best record of South American mammalian faunas prior to Great Biotic Interchange (GABI) and is particular interest because it preserved high-latitude biotic Southern Hemisphere spanning mid-Miocene Climatic Optimum. Through intensive fieldwork we recovered numerous fossil vertebrates, mostly mammal...
