Establishing accurate palaeo-hydroclimatic reconstructions from lacustrine and marine archives is a long-standing challenge in palaeoenvironment studies. Closed-basin evaporites, especially halite, record episodes of extremely arid conditions during rapid climate change. However, the complex limnological behaviour deep hypersaline water bodies stochastic nature hydroclimatic regime its variatio...

Benthic foraminiferal assemblages from Maastrichtian strata, Gansserina gansseri-Abathamphalus mayaroensis Planktonic Foraminiferal Zone, of the AbTalkh Formation at Aitamir section (west of the Kopeh-Dagh basin) were investigated in order to evaluate the palaeoenvironmental changes (organic matter flux and bottom-water oxygenation). Maastrichtian faunal assemblages are well preserved and diver...

The present paper discusses a palaeoenvironmental interpretation of the Oligocene Ogwashi Formation (Niger Delta Basin, Nigeria) through morphometric analysis pebbles, research method essentially depending on quantitative evaluation pebble size and shape which change during transport processes in range depositional environments. relationship bivariate ternary-diagram plots independent functions...

Footprint morphology (e.g., outline shape, depth of impression) is one of the key diagnostic features used in the interpretation of ancient vertebrate tracks. Over 80 tridactyl tracks, confined to the same bedding surface in the Lower Jurassic Elliot Formation at Mafube (eastern Free State, South Africa), show large shape variability over the length of the study site. These morphological differ...

The flora of the Cianowice 2 borehole (c. 20 km NW Cracow, Poland), dominated by cycadophytes (mainly bennettitaleans) and conifers, shows high taxonomic diversity relative to low number specimens. Twenty species were identified in 96 determinable plant fragments found 27 core samples: Cladophlebis sp. (ferns), Pachypteris rhomboidalis (Ettingshausen) Nathorst Ptilozamites cycadea (Berger) Möll...
