Permo-Triassic boundary and Lower to Middle Triassic in South Tibet

Journal of Asian Earth Sciences, 1998
Abstract The abundance of conodonts increases sharply across the Permian/Triassic boundary in South Tibet, and as a consequence Griesbachian assemblages are much better defined than Changxingian ones. The “ Otoceras latilobatum bed”, representing the base of the Triassic at Selong, is a condensed biocalcirudite including abundant macrofossils ...

Paleomagnetism of the Lower Triassic Moenkopi Formation

Geological Society of America Bulletin, 1974
Paleomagnetic studies on the upper half of the Moenkopi Formation have identified three reversed and three normal polarity zones; this brings the total number of polarity zones observed in this formation to ten. The variable thickness and presumed duration of these polarity zones when combined with smaller variations internal to individual polarity ...

A procolophonid reptile from the Lower Triassic of Australia

Zoological Journal of the Linnean Society, 2020
AbstractA new procolophonid reptile from the Lower Triassic Arcadia Formation of Queensland, Australia is described on the basis of abundant cranial and postcranial remains. Eomurruna yurrgensis gen. & sp. nov. is the first parareptile from Australia, being represented by more than 40 specimens from which a detailed description of the osteology is ...
