Maureen Steiner, Pioneer in the Study of the Magnetic Polarity Timescale

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract This perspective is in memory of Maureen Steiner (1944–2023), who was a pioneer in the study of geomagnetism and paleomagnetism. Over an approximately 50‐year‐long career, she made many contributions to the study of geomagnetic history and its application to diverse geological problems.

John W. Geissman: Never Let the You‐Know‐Who's Get You Down—There Is Too Much in Life to Experience and Learn From!

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract My life in science, as a faculty member in Higher Education (The Academy), and as a proud member of AGU, reflects the fact that I am one of the very fortunate ones in the Geosciences who went through undergraduate and graduate years during the true blossoming of the science in the early years after the acceptance of Plate Tectonics.

Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing‐bite among saber‐toothed predators?

The Anatomical Record, Volume 308, Issue 11, Page 2962-2975, November 2025.
Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Sharpening our understanding of saber‐tooth biomechanics

The Anatomical Record, Volume 308, Issue 11, Page 3022-3040, November 2025.
Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...
