Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 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.

Glimpses of ammonite lives [PDF]
Geology Today, Volume 41, Issue 6, Page 260-268, November/December 2025.Ammonites were molluscs, now extinct, that abounded in Mesozoic seas. Their external shells are almost always the only parts of them that are preserved, and their soft‐part anatomy and lifestyles remain largely unknown. The shells, however, can be preserved in various ways that shed light on the animals as living organisms, including their variation ...
