Ecology and Evolution, Volume 14, Issue 11, November 2024.This study introduces a novel approach for quantitatively assessing sea‐surface paleotemperatures examined in the Upper Paleozoic of Siberia. The method relies on evaluating the taxonomic composition of biota. It utilizes a comprehensive dataset encompassing the geographic distribution and ecology of various biotic groups in Siberia and adjacent ...

How to engineer a habitable planet: the rise of marine ecosystem engineers through the Phanerozoic
Palaeontology, Volume 67, Issue 5, September/October 2024.Abstract Ecosystem engineers are organisms that modify their physical habitats in a way that alters resource availability and the structure of the communities they live in. The evolution of ecosystem engineers over the course of Earth history has thus been suggested to have been a driver of macroevolutionary and macroecological changes that are ...

Papers in Palaeontology, Volume 10, Issue 4, July/August 2024.Abstract Blastoids underwent a revolution in respiration in the Devonian. Emsian blastoid faunas were dominated by fissiculates such as Pentremitidea, giving rise to a transitional spiraculate, Conuloblastus. Hyperoblastus and a mosaic of spiraculates followed; they featured a more advanced respiratory system and were dominant until the Permian.

Late Frasnian mass extinction: Conodont event stratigraphy, global changes, and possible causes [PDF]
Several abrupt changes in conodont biofacies are documented to occur synchronously at six primary control sections across the Frasnian-Famennian boundary in Euramerica. These changes occurred within a time-span of only about 100,000 years near the end of
