The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 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.

Evolution in Upper Jurassic Ammonites [PDF]
Evolution, 1959 Evolution in ammonites has been known for nearly a century. It was mainly under the influence of Charles Darwin (1859) that paleontologists began to look for successions of similar species and to connect these species into lineages. These early studies of evolution in ammonites are due to, e.g., Waagen (1869), Neumayr (1873) and Gemmellaro (1872-82 ...
