Sea level changes versus hydrothermal diagenesis: Origin of Triassic carbonate platform cycles in the Dolomites, Italy: Discussion [PDF]
In his recent paper, Blendinger (2004) presents a new and unconventional hypothesis for the formation of the Triassic Latemàr carbonate cycles. He assigned the cycles to intermittent hydrothermal influence alternating with normal marine deposition ...

Abstract Phylogenetic comparative methods have been used in recent literature to work with laws and test for regularities (evolutionary associations of quantitative features) and evolutionary singularities (features that evolved in a single taxon). We analyzed these uses epistemologically, taking the evolution of red‐blood‐cell mean corpuscular volume (

Life after extinction: palaeoenvironments of the earliest Triassic lower Katberg formation, including the origin of Lystrosaurus Bonebeds from the Karoo Basin, South Africa [PDF]
Includes abstract.Includes bibliographical references.This study argues for the formation of bonebeds by aggregation of sub-adult Lystrosaurus during extended episodic periods of extreme climatic conditions, such as cold or drought, in the earliest ...

A new species of the equisetalean plant Equicalastrobus from the Middle Triassic of Argentina [PDF]
We present a morphological-systematic study of new fossil specimens of equisetaleans (horsetails) from the Cortaderita Formation, Sorocayense Group, Middle Triassic, Cuyana Basin, southwest of the San Juan Province, Argentina.

The Triassic radiation of the entomofauna
Assessing the insect evolution around the Permian/Triassic boundary faces various pitfalls. The taxonomic and phylogenetic frames are not consensually established, and diverse evidences suggest that the record is incomplete. Nevertheless, extensive studies in progress on the super-ordinal clades Archaeorthoptera and Odonatoptera reveal common trends ...

Anisian (Middle Triassic) Conodonts of the Kocaeli Triassic, Western Turkey
The present study of Anisian (Middle Triassic) conodonts from the Kocaeli Peninsula (western Turkey) encompasses over 10 species of the families Gondolellidae and Gladigondolellidae, providing Early and Middle Triassic time constraints, Chiosella timorensis (Nogami, 1968); Cornudina oezdemirae Gedik, 1975; Gladigondolella tethydis (Huckriede, 1958 ...

Ages from the “Mogod Formation” of the Permian–Triassic igneous rocks in the Sayan–Baikal belt, northern Mongolia [PDF]
Late Paleozoic–Early Mesozoic volcano-plutonic rock unit at the southern margin of the Sayan–Baikal belt, Mongolia is a significant factor in understanding the Paleozoic–Mesozoic arc system along the Siberian continental margin.

Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

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.

Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.
