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.

Early Triassic hothouse conditions limited marine productivity

2023
The Early Triassic represents a period of prolonged recovery following the most severe extinction of the Phanerozoic. Records show this to be a period of extremely high global temperatures, likely driven by Siberian Traps eruption induced global warming.

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 ...

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.

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 ...

Early Triassic tetrapod faunas of southeastern Gondwana

Alcheringa: An Australasian Journal of Palaeontology, 1986
A modified version of the Simpson index is used to assess similarities between the Early Triassic tetrapod faunas of Australia, Antarctica, India and South Africa. This index takes into account the relative abundances of taxa, and not merely their presence or absence.

[Cranial bone neoplasm in early triassic amphibia].

Voprosy onkologii, 2001
A neoplasm in cranial bone of an early Triassic amphibian has been investigated. Although no tissue has survived, the cranial flat bone is similar to that in living animals of the same class. Evidence is presented in support of a hypothesis that the neoplasm is a skeletal tumor which consists of non-functional bone and looks like an atypical tumorous ...
