Vegetation context and climatic limits of the Early Pleistocene hominin dispersal in Europe [PDF]

open access: yes, 2010
The vegetation and the climatic context in which the first hominins entered and dispersed in Europe during the Early Pleistocene are reconstructed, using literature review and a new climatic simulation. Both in situ fauna and in situ pollen at the twelve

Early Cretaceous biogeographic and oceanographic synthesis of Leg 123 (off Northwestern Australia) [PDF]

open access: yes, 1992
Biogeographic observations made by Leg 123 shipboard paleontologists for Lower Cretaceous nannofossils, foraminifers, radiolarians, belemnites, and inoceramids are combined in this chapter to evaluate the paleoceanographic history of the northwestern ...

PALEOBIOGEOGRAPHY OF SOUTHERN HEMISPHERE DECAPOD CRUSTACEA [PDF]

open access: yesJournal of Paleontology, 2006
Paleobiogeographic patterns of decapod crustaceans from the Southern Hemisphere, based upon 441 species-level records arrayed in 154 genera, document global patterns of distribution that can be compared to those previously published on decapods from the North Pacific and Central American regions.

Major Shifts in Equatorial Atlantic and Pacific Calcareous Nannofossil Assemblages Across the Early Eocene Climatic Optimum (EECO; ∼53–49 Ma)

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.
Abstract The early Eocene Climatic Optimum (EECO; ∼53–49 Ma) was the warmest sustained global warming episode of the Cenozoic, accompanied by major alterations in terrestrial and marine biota. Here we detail changes in low‐latitude calcareous nannofossil assemblages at two tropical sites in the equatorial Atlantic (ODP Site 1258) and Pacific (ODP Site ...

Brachiopod faunal exchange through an epioceanic-epicontinental transitional area from the Early Jurassic South Iberian platform system [PDF]

open access: yes, 2016
The La Mola region (eastern External Betic Zone) can be regarded as one of the easternmost complete Jurassic successions of the Betic Cordillera in the Iberian Peninsula, but the paleogeographical setting of their outcrops remains widely discussed ...

Fishes from the Upper Cretaceous Prince Creek Formation, North Slope of Alaska, and their palaeobiogeographical significance

open access: yesPapers in Palaeontology, Volume 11, Issue 3, May/June 2025.
Abstract The Upper Cretaceous Prince Creek Formation (PCF) of northern Alaska offers a unique glimpse into northern high‐latitude, non‐marine vertebrate assemblages, providing critical data on polar ecosystems during the late Campanian (c. 73 Ma).
