Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Environmental distribution of Bathonian (Middle Jurassic) neoselachians in southern England [PDF]
, 2004 Within the Bathonian (Middle Jurassic) a wide range of depositional environments were present across Britain. Within this dominantly carbonate shelf setting, there is a general palaeoenvironmental transition from open marine shelf in the south of England,

A Geochemistry study of the Sargelu Formation (Middle Jurassic) in terms of original mineralogy and palaeotemperature in the Lorestan area [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2022 The carbonate Sargelu Formation (Middle Jurassic) in the Lorestan area mainly consists of black calcareous shales and thin- to thick-bedded limestones with remarkable organic material. Integrated binary diagrams of trace elements and stable isotopes such
