Warm tropical sea surface temperatures in the Late Cretaceous and Eocene epochs
New data from exceptionally well preserved foraminifer shells extracted from impermeable clay-rich sediments indicate that for the intervals studied, tropical sea surface temperatures were at least 28–32 °C, more in line with the understanding of the geographical distributions of temperature-sensitive fossil organisms and the results of climate models with increased CO2 levels.
Earliest Archaeological Evidence of Persistent Hominin Carnivory
Three large well-preserved zooarchaeological assemblages from Kanjera South, Kenya are detailed, providing the earliest archaeological evidence of sustained hominin involvement with fleshed animal remains (i.e., persistent carnivory), a foraging adaptation central to many models of hom inin evolution.
Small Mid-Pleistocene Hominin Associated with East African Acheulean Technology
Although the cranium represents possibly the smallest adult or near-adult known between 1.7 and 0.5 Ma, it retains features observed in larger Homo erectus individuals, yet shows a distinct suite of traits indicative of wide population variation in the hominins of this period.
Palaeoceanographic events in the Middle Cenomanian of Northwest Europe
Six rhythmic (chalk/marl) mid-Cenomanian sections have been studied: Culver Cliff, Southerham, Folkestone and Cap Blanc Nez (Anglo-Pads Basin); Speeton, South Ferriby (Cleveland Basin, UK).
Oldest Evidence of Toolmaking Hominins in a Grassland-Dominated Ecosystem
These data demonstrate that grassland-dominated ecosystems did in fact exist during the Plio-Pleistocene, and that early Homo was active in open settings, and indicates that by 2.0 Ma hominins, almost certainly of the genus Homo, used a broad spectrum of habitats in East Africa, from open grassland to riparian forest.
