Lithics and cut-marked mammal bones, excavated from the paleo-lake Marathousa 1 (MAR-1) sediments in Megalopolis Basin, southern Greece, indicate traces of hominin activity occurring along a paleo-shoreline ca. 444,000 years (444 ka) ago. However, local environment climatic conditions promoting area during MIS12 glacial remain largely unknown. In order to reconstruct paleo-environment including...

rents; (4) specific water masses; (5) conditions of preservation; (6) presence and strength of upwelling onto shelves and under boundary currents; (7) eutrophic conditions; and (8) tectonic events (isolating radiolarian populations). These biologic indicators and their related forms are useful in determining similar parameters in the fossil record. Studies of radiolarians from Neogene Deep Sea ...

Abstract In freshwater systems (rivers and lakes), historical recent tsunamis have been documented their traces found in the geological record, but studies of paleotsunamis (prehistorical tsunamis) such environments are still underrepresented. This contribution reviews paleotsunami with a focus on post ?2011 period uses events to highlight some areas research that received little attention. pas...

Catastrophic drainage of glacial Lake Missoula through the Columbia River Gorge, USA, produced some largest floods ever known. However, erosion gorge during flooding has not been quantified, hindering discharge reconstructions and our understanding landscape change by megafloods. Using a neural network field observations, we reconstructed topography found ?7.4 km3 rock was eroded from walls. Ac...
