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.

Eocene phymaraphiniid demosponges from South Western Australia: filling the gap
Acta Palaeontologica Polonica, 2023 We describe two new genera of phymaraphiniid lithistid sponges Twertupia gen. nov. and Pickettispongia gen. nov. from the upper Eocene Pallinup Formation of South Western (SW) Australia based on new, rich and very well preserved material. Type material

A new species and a key to Isomira Mulsant, 1856 (Coleoptera: Tenebrionidae: Alleculinae) from Eocene Baltic amber [PDF]
Кавказский энтомологический бюллетень, 2021 Based on a single well-preserved specimen from Eocene Baltic amber, a new comb-clawed beetle Isomira lobanovi sp. n. (Alleculinae: Alleculini: Gonoderina) is described and illustrated.

Scaled biotic disruption during early Eocene global warming events [PDF]
, 2012 Late Paleocene and early Eocene hyperthermals are transient warming events associated with massive perturbations of the global carbon cycle, and are considered partial analogues for current anthropogenic climate change.

Organic Carbon Burial following the Middle Eocene Climatic Optimum (MECO) in the central - western Tethys [PDF]
, 2010 We present trace metal geochemistry and stable isotope records for the middle Eocene Alano di Piave section, NE Italy, deposited during magnetochron C18n in the marginal Tethys Ocean. We identify a $\sim$ 500 kyr long carbon isotope perturbation event we
