“…This scenario is consistent with the western Tethys studies, which also revealed a cooling interval during the Norian-Rhaetian transition, as indicated by higher oxygen isotope (δ 18 O) records from conodont apatite (Trotter et al, 2015). The climate change across the Norian-Rhaetian boundary may be caused by emplacement of large volcanic event, although no LIP dated to this time is known to date (Rigo et al, 2020).…”

“…The next big mass extinction is known from the end-Triassic, and it occurred during most of the Rhaetian Stage [ 54 , 55 , 96 , 97 , 98 , 99 , 100 ]. This biotic catastrophe corresponds to an outstanding global sea-level fall followed by a similar rise and subsequent changes of lesser magnitude as depicted by Haq [ 33 , 34 ] ( Figure S1 ).…”

Recent eustatic reconstructions allow for reconsidering the relationships between the fifteen Paleozoic–Mesozoic mass extinctions (mid-Cambrian, end-Ordovician, Llandovery/Wenlock, Late Devonian, Devonian/Carboniferous, mid-Carboniferous, end-Guadalupian, end-Permian, two mid-Triassic, end-Triassic, Early Jurassic, Jurassic/Cretaceous, Late Cretaceous, and end-Cretaceous extinctions) and global sea-level changes. The relationships between eustatic rises/falls and period-long eustatic trends are examined. Many eustatic events at the mass extinction intervals were not anomalous. Nonetheless, the majority of the considered mass extinctions coincided with either interruptions or changes in the ongoing eustatic trends. It cannot be excluded that such interruptions and changes could have facilitated or even triggered biodiversity losses in the marine realm.

“…Importantly though, other distinct extinction events during the Late Triassic (Brusatte, Nesbitt, et al, 2010) are not associated with any known external forcing factors. Because of this complexity, the very premise of a singular end‐Triassic mass extinction event has been questioned (Hallam & Wignall, 1999; Lucas & Tanner, 2018; Rigo et al, 2020).…”

Geological control on dinosaurs’ rise to dominance: Late Triassic ecosystem stress by relative sea level change

2020

View full text Add to dashboard Cite

The Late Triassic is enigmatic in terms of how terrestrial life evolved: it was the time when new groups arose, such as dinosaurs, lizards, crocodiles and mammals. Also, it witnessed a prolonged period of extinctions, distinguishing it from other great mass extinction events, while the gradual rise of the dinosaurs during the Carnian to Norian remains unexplained. Here we show that key extinctions during the early Norian might have been triggered by major sea‐level changes across the largest delta plain in Earth's history situated in the Triassic Boreal Ocean, northern Pangea. Fossil and rock records display extensive marine inundations with floral turnover, demonstrating how susceptible widespread low‐gradient delta plains were to transgressions. Landward shoreline translocation implies decrease in important coastal regions and ecological stress on the dominant Archosauria, thriving in these habitats, and we argue that these unique geological factors played an important role in dinosaurs gradual rise to dominance.
