New information on Late Triassic sauropodomorph dinosaurs provides support for the independent acquisition of postcranial skeletal pneumaticity in avemetatarsalian lineages

Journal of Anatomy, Volume 248, Issue 3, Page 541-578, March 2026.
PSP in early‐branching sauropodomorphs probably evolved first in the neural arches of the posterior cervical vertebrae, expanding anteriorly and posteriorly along the vertebral column. The distribution of PSP in Late Triassic early‐branching sauropodomorphs does not appear to be correlated with body size.

Probabilistic Identification of Parameters in Dynamic Fracture Propagation

International Journal for Numerical Methods in Engineering, Volume 127, Issue 4, 28 February 2026.
ABSTRACT In this paper, we propose a novel multiphase approach for identifying input parameters in dynamic fracture propagation. Often, such parameters are partially known and uncertain with incomplete input data, resulting in challenges in predicting a reliable dynamic failure response.

Irreversible Transitions of the Ocean Circulation in Antarctic Ice‐Shelf Cavities

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Ice shelves fringing the Antarctic continent experience low or high basal melt rates depending on local shelf conditions, ocean circulation and intensity of ice‐sea‐air exchanges. Recent studies have uncovered potential cold‐to‐warm transitions in specific ice‐shelf cavities, which could lead to a dramatic increase in sea‐level rise.
