BACKGROUND Phorusrhacidae was a clade including middle-sized to giant terrestrial carnivorous birds, known mainly from the Cenozoic of South America, but also occurring in the Plio-Pleistocene of North America and the Eocene of Africa. Previous reports of small phorusrhacids in the Paleogene of Europe have been dismissed as based on non-phorusrhacid material. METHODOLOGY we have re-examined s...
Abstract Recent discovery of a previously unknown outcrop in the vicinity Zengővárkony lime-kilns (Mecsek Mountains, Hungary) provided few identifiable upper Oxfordian brachiopods that exhibit truly Mediterranean (Tethyan) character. Dating is based on rich ammonite fauna: Benetticeras benettii; Trimarginites ex gr. trimarginatus; Orthosphinctes (Orthosphinctes) tiziani clearly indicate Late Ox...
Located at the westernmost tip of Mediterranean, Gibraltar Arc is a segment Alpine belt that exhibits peridotite massifs associated with high-grade crustal metamorphic units. The timing and mechanisms exhumation these crust–mantle associations are still debated in Rif Morocco as well Betic Cordilleras Spain. A structural, petrographic, geochronological study ( 40 Ar– 39 Ar method) performed Ben...
The South China Block is situated in the Eastern Asian margin. Since Neoproterozoic, its tectonic evolution was constrained by successive consumption-closure processes of Paleo-South China, Proto-Tethys, Paleo-Tethys, and Paleo-Pacific oceans. Studies suggest that this block initially formed Neoproterozoic assembly Yangtze Cathaysia blocks following subduction-accretion Ocean. Then after, it ex...
Late Liassic in the Western Tethys has been cradle of Middle and Jurassic diversity corals. This is what revised enhanced taxonomy corals from Pliensbachian Toarcian stages reveals. The current new taxonomic study describes 66 species distributed 41 genera 20 identified families. It includes four genera: Podosmilia n. gen., Tubulosmilia Prismastrea gen. Spongiocoenia gen.; species: Axosmilia am...
Tsunami waves are the most underrated hazard affecting the life near coastal belts. With socio-economic developments in coastal region results in more hazardous from tsunami. The hazard assessment of tsunami is highly vital. The Makran region is exceptional in closure zone of Tethys; it is only segment east of the Mediterranean and west of Andaman arc in which subduction of oceanic lithosphere ...
