Mesozoic Coleopteran Faunas fromArgentina: Geological Context, Diversity, Taphonomic Observations, and Comparison with Other Fossil Insect Records [PDF]
The order Coleoptera is the most diversified group of the Class Insecta and is the largest group of the Animal Kingdom. This contribution reviews the Mesozoic insects and especially the coleopteran records from Argentina, based on bibliographical and ...

Deposition during the Triassic continued in the basinal areas developed during the Permian, but in Early Triassic the highs were also gradually covered by sediments. The pattern of sedimentation in the two mega-basins is analogous to that of the Rotliegendes, i.e. with a pronounced, more coarse-grained elastic infill in the northern basin (fig.

A Triassic-Jurassic window into the evolution of Lepidoptera
The oldest ancestors of moths and butterflies evolved in a gymnosperm world. On the basis of an assemblage of fossilized wing scales recovered from latest Triassic and earliest Jurassic sediments from northern Germany, we provide the earliest evidence ...

Stratigraphy, facies and geodynamic settings of Jurassic formations in the Bükk Mountains, North Hungary: its relations with the other areas of the Neotethyan realm. [PDF]
Jurassic mélange complexes related to the subduction of the Neotethys Ocean occur in the Bükk Mountains, North Hungary. This paper characterizes the sedimentary sequence of basin and slope facies that occur in the southwestern part of the Bükk ...

A Triassic plesiosaurian skeleton and bone histology inform on evolution of a unique body plan
The first plesiosaur skeleton from the Triassic informs about the evolutionary success of four-flippered marine reptile. Secondary marine adaptation is a major pattern in amniote evolution, accompanied by specific bone histological adaptations.

The relationships of the Euparkeriidae and the rise of Archosauria [PDF]
For the first time, a phylogenetic analysis including all putative euparkeriid taxa is conducted, using a large data matrix analysed with maximum parsimony and Bayesian analysis. Using parsimony, the putative euparkeriid Dorosuchus neoetus from Russia is

Road and bridge construction across gypsum karst in England [PDF]
Gypsum karst problems in the Permian and Triassic sequences of England have caused difficult conditions for bridge and road construction. In Northern England, the Ripon Bypass crosses Permian strata affected by active gypsum karst and severe subsidence ...

The Shublik Formation within the project area is an unconformity-bounded assemblage of carbonates and clastics of Middle and Late Triassic age. It is characterized by two distinct facies: nearshore depositional environments to the north, and deeper water and organic-rich facies to the south.
