The present work focuses on palaeogeographic reconstruction of shallow-water carbonate deposition in the Outer Western Carpathian Tethys. Platform deposits are preserved only as a component turbidites and olistostromes, reconstructions these platforms based clastic material redistributed into slopes deep basins occurring among nappes. Similar were also Tethys margins. These performed using glob...
Limestones designated the Štramberk-type are most common carbonate exotic clasts (exotics) embedded in uppermost Jurassic–Miocene flysch deposits of Polish Outer Carpathians. About 80% stratigraphically determinable exotics from Silesian, Sub-Silesian and Skole units (nappes) Tithonian (mostly)–Berriasian (sporadically Valanginian) age. A study these revealed eight main facies types: coral-micr...
BACKGROUND Heterodontosaurids are an important but enigmatic and poorly understood early radiation of ornithischian dinosaurs. The late-surviving heterodontosaurid Fruitadens haagarorum from the Late Jurassic (early Tithonian) Morrison Formation of the western USA is represented by remains of several small (<1 metre total body length, <1 kg body mass) individuals that include well-preserved but...
BACKGROUND Ichthyosaurs are reptiles that inhabited the marine realm during most of the Mesozoic. Their Cretaceous representatives have traditionally been considered as the last survivors of a group declining since the Jurassic. Recently, however, an unexpected diversity has been described in Upper Jurassic-Lower Cretaceous deposits, but is widely spread across time and space, giving small clue...
