Fluvial sequence stratigraphy and paleoclimate of the Upper Triassic (Norian-Rhaetian) Chinle Strata, northern New Mexico.
Two age-equivalent Upper Triassic (Norian and Rhaetian) fluvial successions in New Mexico were evaluated from a sequence-stratigraphic and paleopedologic perspective. Meter-scale fining-upward fluvial aggradation cycles (FACs) comprise fluvial aggradational cycle sets (FACSETs) 4-15 m thick. …

Marine Deoxygenation Predates the End-Triassic Mass Extinction Within the Equatorial Panthalassa and its Influence on Marine Ecosystems Before the Biotic Crisis
… marine nitrogen cycle and redox across the upper Norian Stage of the Triassic through lower Hettangain Stage of the Jurassic (~215 to 198 million years ago). The geologic succession at Grotto Creek represents deeper water marine deposition in eastern equatorial Panthalassa, likely capturing …

Triassic-Jurassic biochronology of the eastern Iskut River map area, northwestern British Columbia
Norian to Early Callovian faunas in the eastern half of the Iskut River map area can be divided into three suites: a benthonic fauna consisting of bivalves, corals, and gastropods; a planktonic fauna of radiolarians; and a nektonic fauna of coleoids and ammonoids. The ammonoids (27 genera, 47 …

Discovering the last Triassic giant: Insights from the marine Late Triassic of Nevada and a new ichthyosaur locality from New York Canyon, Nevada, USA.
… the Luning Formation, which is assigned an early Norian age. Most of the material is likely referable to Shonisaurus and consists of partly to completely disarticulated vertebrae, rib, girdle, and limb elements, with rarer cranial material. Isolated bones from the upper member of the Luning …

Paleomagnetism of Late Triassic and Jurassic sediments of the southwestern United States.
… stratigraphic succession. During the Carnian and Norian stages of the Late Triassic, Chinle poles progress westward. During the Hettangian through Pliensbachian stages of the Early Jurassic, the pattern of APW changed to an eastward progression. Even after correction for 4° clockwise rotation of …

NEARING THE END: REEF BUILDING CORALS AND BIVALVES IN THE LATE TRIASSIC AND COMPARING CORALS AND BIVALVES BEFORE AND AFTER THE END-TRIASSIC MASS EXTINCTION USING A TAXONOMIC DATABASE
… as reef building corals and bivalves. During the Norian and Rhaetian (Late Triassic), corals and bivalves had high diversity and abundance, but like many organisms involved in the mass extinction, quickly disappeared at the end of the Triassic. In the early Jurassic, very few surviving species of …

Geology of the central Moresby Island region, Queen Charlotte Islands, (Haida Gwaii) British Columbia
… indicate a volcanic provenance as early as the Norian. The Early to Middle Jurassic marine sedimentary rocks of the Maude Group, present elsewhere in the Queen Charlotte Islands, are absent in central Moresby Island. Oldest rocks of the clastic Longarm Formation in central Moresby Island are of …

Evaluation of tridactyl theropod tracks in southern Africa: quantitative morphometric analysis across the Triassic–Jurassic boundary
… Stormberg Group. More specifically, the middle Norian – Pliensbachian Elliot and Clarens formations (upper Stormberg Group) of main Karoo Basin, host a diverse tetrapod osteological and ichnite record. Due to an absence of high resolution radioisotopic age determinations, the exact stratigraphic …
