New deep-water brachiopod resilient assemblage from the South-Iberian Palaeomargin (Western Tethys) and its significance for the brachiopod adaptive strategies around the Early Toarcian Mass Extinction Event [PDF]
, 2017 The Pliensbachian-Toarcian transition was a period of changes in long-term environmental conditions leading up to the Early Toarcian Mass Extinction Event (ETMEE), which resulted in a noticeable extinction and turnover in the marine biota.

Ten Years of Toarcian Argillite - Carbon Steel In Situ Interaction
Procedia Earth and Planetary Science, 2013 AbstractIn situ interaction experiments over periods of 2, 6, and 10 years between Toarcian argillite and carbon steel discs were carried out in the Tournemire Underground Research Laboratory (URL), yielding a dataset of the materials’ geochemical evolution under conditions representative of the future geological disposal of high-level long-lived ...

First teuthid cephalopod from the Lower Jurassic of South America (Neuquén Basin, Argentina)
Geologica Acta, 2005 A new species of squid, Teudopsis jeletzkyi n. sp., is described from the Toarcian (Lower Jurassic) of the Los Molles Formation in Neuquen Province, central west Argentina. Fossil squids have thus far been unknown in the Mesozoic of South America.

The Jurassic of Denmark and Greenland: The Lower Jurassic of Europe: its subdivision and correlation [PDF]
Geological Survey of Denmark and Greenland Bulletin, 2003 The Lower Jurassic Sub-system comprises four stages, in chronological order, the Hettangian, Sinemurian, Pliensbachian and Toarcian. Each stage is subdivided into a sequence of `standard zones' (= chronozones) and subzones - each correlated primarily on ...
