Perissodactyla of the Sespe Eocene, California [PDF]

open access: yesProceedings of the National Academy of Sciences, 1936
One of the outstanding peculiarities of the Eocene faunas known from the Sespe deposits of California is the continued absence of any evidence of the Equidae. Aside from lack of representatives of this family, however, the Perissodactyla include members of the Rhinocerotoidea and Brontotheriidea.

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

open access: yesBoreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Amber deposits of Ukraine and prospects of their development

open access: yesМінеральні ресурси України, 2017
Geological conditions for formation and territorial distribution of amber deposits in Ukraine have been analyzed. Amber deposits for jewelry production are connected with the Baltic-Dnieper Subprovince within the Ukrainian part of which two amber-bearing

Palaeoceanographic change during the Palaeocene/Eocene thermal maximum in Arctic Spitzbergen

open access: yes, 2011
The interaction of the ocean, atmosphere and ice in the Arctic region plays a critical role in modulating global climate. However, recent observations have illustrated the region is changing rapidly in response to anthropogenically-induced warming. Given

Exploring the controls on element ratios in middle Eocene samples of the benthic foraminifera Oridorsalis umbonatus

open access: yes
Culturing studies and empirically based core top calibrations have been used to infer that elemental ratios in benthic foraminifera can be used as proxies to reconstruct past variations in bottom water temperature and saturation state (Δ [CO32 ...
