[1] The late Paleocene to the early Eocene ( 58–52 Ma) was marked by significant changes in global climate and carbon cycling. The evidence for these changes includes stable isotope records that reveal prominent decreases in ı18O and ı13C, suggesting a rise in Earth’s surface temperature ( 4ıC) and a drop in net carbon output from the ocean and atmosphere. Concurrently, deep-sea carbonate recor...

Hyaenodonta is a diverse, extinct group of carnivorous mammals that included weasel- to rhinoceros-sized species. The oldest-known hyaenodont fossils are from the middle Paleocene of North Africa and the antiquity of the group in Afro-Arabia led to the hypothesis that it originated there and dispersed to Asia, Europe, and North America. Here we describe two new hyaenodont species based on the o...

[1] Uppermost Cretaceous to Eocene marine sedimentary sequences occur both to the south and north of the Yarlung Zangbo suture in south central Tibet. They consist of Indian-margin strata of the northern Tethyan Himalaya and Asian-margin strata of the Gangdese forearc. Both assemblages are characterized by major changes in depositional environment and sedimentary provenance at 65 Ma and an appe...

New evidence gained by the study of Foraminifera from Khuzestan province in southwest Iran reveals that the basal limit of the genus Heterostegina is not restricted to the Eocene epoch. By introducing a new species of this genus (H. rezvaninejadi), this study shows that the early appearance of this genus should be lowered down further still, at least, into the Middle Paleocene.
