Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

Meteoritics &Planetary Science, EarlyView.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

A NEW DICTYOPYGID FROM THE CAVE SANDSTONE OF LESOTHO, SOUTHERN AFRICA [PDF]

, 1973
The Lower Triassic of South Africa has yielded an array of early dictyopygids (Brough, 1931, 1936) yet none of those advanced dictyopygids so characteristic of the Upper Triassic of North America (Schaeffer, 1967) has so far been recorded from the ...

MISS diversity from saline lakes of Brazilian Pantanal: Origin, potential of preservation and comparison with examples of the Ediacaran‐Cambrian shallow depositional settings

Sedimentology, EarlyView.
ABSTRACT One of the largest wetlands on Earth, the Brazilian Pantanal contains roughly 10 000 natural lakes, about 1000 of which are hypersaline. In these environmentally stressful settings, animal life struggles to survive, while cyanobacteria form extensive mats.

TOOTH MORPHOTYPES SHED LIGHT ON THE PALEOBIODIVERSITY OF MIDDLE TRIASSIC TERRESTRIAL VERTEBRATE ECOSYSTEMS FROM NE IBERIAN PENINSULA (SOUTHWESTERN EUROPE)

Rivista Italiana di Paleontologia e Stratigrafia
The Early to Middle Triassic is a key time interval in tetrapod evolution. After the end-Permian biotic crisis, harsh environmental conditions due to global warming and aridity persisted during the Early Triassic.

Disentangling palaeoecological and outcrop controls on MISS occurrence in c. 1 Ga fluvio‐lacustrine facies of the Diabaig Formation, Scotland

Sedimentology, EarlyView.
ABSTRACT The c. 1 Ga Diabaig Formation of north‐west Scotland preserves diverse lacustrine and fluvial facies and abundant microbial and non‐microbial surficial sedimentary features. 172.6 m of section was logged across seven localities to assess the distribution of microbially induced sedimentary structures (MISS) relative to lithofacies, substrate ...

A tale of two microbialites: Stromatolites and microbially induced sedimentary structures

Sedimentology, EarlyView.
ABSTRACT Microbialites are biosedimentary structures built by microbial mats. Five microbialite groups are distinguished: stromatolites, thrombolites, dendrolites, leiloites and microbially induced sedimentary structures (MISS). This contribution discusses the two most abundant microbialite groups in marine settings, stromatolites and MISS.
