Phytogeography of Eurasia during the early triassic

Palaeogeography, Palaeoclimatology, Palaeoecology, 1987
Abstract New data of Chinese and Soviet palaeontologists and stratigraphers allow correlation between the Triassic plant-bearing beds of Siberia, China and western Europe. The early Triassic floras of these regions were much more connected than supposed.

Lethally Hot Temperatures During the Early Triassic Greenhouse

Science, 2012
Too-Hot TimesClimate warming has been invoked as a factor contributing to widespread extinction events, acting as a trigger or amplifier for more proximal causes, such as marine anoxia.Sunet al.(p.366; see the Perspective byBottjer) present evidence that exceptionally high temperatures themselves may have caused some extinctions during the end-Permian.

A Triassic Fauna from Madagascar, Including Early Dinosaurs

Science, 1999
The discovery of a Middle to Late Triassic (∼225 to 230 million years old) terrestrial vertebrate fauna from Madagascar is reported. This fauna documents a temporal interval not well represented by continental vertebrate assemblages elsewhere in the world. It contains two new prosauropod dinosaurs, representing some of the earliest dinosaur occurrences

Early Triassic paleomagnetism and tectonics, South China

Journal of Southeast Asian Earth Sciences, 1993
Abstract New preliminary paleomagnetic results from the Lower Triassic limestones in several representative localities of South China support the existence of displaced blocks proposed by Hsu et al. (1988) “Huanan Alps, not South China Platform.” Sci. Sin.(B) , 31 , 109–119. and Hsu et al.

Retrograde Evolution of Early Triassic Conodonts

2016
Iterative evolution, with repetition of heterochronous homeomorph lineages, is the most frequent type of evolution shown by Triassic conodonts. One specific example of such evolutionary modes is given in the present chapter. Like in ammonoids, they are accompanied by typical geometrical simplification during the transition between the ancestors and ...

A review of selected triassic to Early Cretaceous ferns

Journal of Plant Research, 1994
After becoming nearly extinct during the Permian, the ferns began a slow recovery during the Triassic as the climate of the earth moderated. As a result, a considerable number and variety were present and widely distributed during the Jurassic and Early Cretaceous.

A proterosuchian reptile from the Early Triassic of Tasmania

Alcheringa: An Australasian Journal of Palaeontology, 1978
A proterosuchian reptile, Tasmaniosaurus triassicus gen. et sp. nov. was found in a pond deposit within the Knocklofty Formation of Early Triassic age near Hobart, southern Tasmania. It is the first evidence of this group in Australia. It shows many similarities with Proterosuchus and Euparkeria but some similarities to other proterosuchians ...

Early Triassic proliferation of microbial deposit

2019
In modern examples of well-developed microbial-dominated deposits associated with metazoan organisms can be currently found in various environments including but not restricted to lagoons in Polynesia (Sprachta et al., 2001), the warm water of the Cuba (e.g., Bouton et al., 2016; Pace et al., 2018), the hypersaline lakes of the Great Salt Lake (USA; e ...

Late Triassic and Early Jurassic palaeogeography of the world

Palaeogeography, Palaeoclimatology, Palaeoecology, 2007
Abstract A new version of global and regional palaeogeographic maps is presented for two time intervals. These maps depict the plate tectonic configuration, palaeoenvironment and lithofacies during the Late Triassic (Carnian–Norian) and Early Jurassic (Hettangian–Toarcian) time. The individual maps illustrate the general conditions present during the

The Permian-Triassic boundary and the early Triassic sedimentation in the western peritethys basins: An overview

2007
At the scale of the peri-Tethyan basins of western Europe, the "Buntsandstein" continental lithostratigraphic units are frequently attributed to the "Permian-Triassic" because, in most cases, the lack of any "Scythian" (i.e. Early Triassic) biochronological evidence makes it very difficult to attribute the basal beds of the cycle to the Permian or to ...
