A unique Sphenophyllum-mimicking insect in the Permian [PDF]
BMC BiologyBackground Mimicry is an adaptive strategy widespread in modern ecosystems, yet its deep-time origins and evolution remain poorly understood due to the scarcity of unequivocal fossil evidence.

Strontium Isotope Stratigraphy: LOWESS Version 3: Best Fit to the Marine Sr‐Isotope Curve for 0–509 Ma and Accompanying Look‐up Table for Deriving Numerical Age [PDF]
Journal of Geology, 2001 An improved and updated version of the statistical LOWESS fit to the marine 87Sr/86Sr record and a revised look-up table (V3:10/99; available from j.mcarthur@ucl.ac.uk) based upon it enables straightforward conversion of 87Sr/86Sr to numerical age, and ...

Seismogenic potential and tsunami threat of the strike-slip Carboneras fault in the western Mediterranean from physics-based earthquake simulations [PDF]
Natural Hazards and Earth System Sciences, 2023 Strike-slip fault ruptures have a limited capacity to generate vertical deformation, and for this reason they are usually dismissed as potential destructive tsunami sources.

The Llandovery (Silurian) conodont species diversity on the Upper Yangtze Platform, South China [PDF]
Estonian Journal of Earth Sciences, 2014 Conodonts are one of the stratigraphically most important fossil groups in the Silurian Period. We examine the regional diversity dynamics of the Llandovery condonts on the Upper Yangtze Platform.
