Multiproxy constraints on recovery processes during the hyperthermal Toarcian Oceanic Anoxic Event

2023
Extreme and rapid climatic and environmental perturbations have punctuated Earth history. The causes and consequences of these past global-change events are relatively well constrained, but how the system can naturally recover through feedbacks remain largely unconstrained.

Expression of the Toarcian Oceanic Anoxic Event: New insights from a Swiss transect

Sedimentology, 2018
AbstractA sedimentological, biostratigraphical and geochemical (stable isotopes and Rock‐Eval parameters) analysis was performed on four Swiss successions, in order to examine the expression of the Toarcian Oceanic Anoxic Event along a north–south transect, from the Jura through the Alpine Tethys (Sub‐Briançonnais and Lombardian basins).

Opportunistic behaviour after the Toarcian Oceanic Anoxic Event: The trace fossil Halimedides

Palaeogeography, Palaeoclimatology, Palaeoecology, 2019
Abstract We present an analysis of the first well-documented record of the trace fossil Halimedides in Lower Jurassic (Toarcian) sediments, from the West Iberian Palaeomargin (Lusitanian Basin, Portugal). The abundant and well-preserved specimens allow a detailed ichnological characterization, supporting interpretation of the associated ...

Ichnology of the Toarcian Oceanic Anoxic Event: An understimated tool to assess palaeoenvironmental interpretations

Earth-Science Reviews, 2021
Abstract The Toarcian Oceanic Anoxic Event (T-OAE; ~183 Ma) of the Early Jurassic period is considered a second-order bioevent, of major importance in the Mesozoic. This event determined significant changes in the existing biota, including the extinction of some 15–20% of marine families and genera, while also affecting continental groups.
