Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha

Journal of Anatomy, Volume 249, Issue 6, Page 1368-1427, December 2026.
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

Chronostratigraphic terminology at the Paleocene/Eocene boundary

, 2003
Integrated research over the past decade has led to the recognition of a short (150-200 k.y.) interval of Paleogene time within Chron C24r at ~55.5 Ma, formerly termed the late Paleocene Thermal Maximum (LPTM) but more recently the Paleocene-Eocene Thermal Maximum (PETM), that was crucial in the climatic, paleoceanographic, and biotic evolution of our ...

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, Volume 309, Issue 11, Page 3106-3122, November 2026.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Assessing the Duration of the Paleocene‐Eocene Thermal Maximum [PDF]

Geophysical Research Letters
Abstract The Paleocene‐Eocene Thermal Maximum (PETM) was a climate/carbon cycle perturbation recognized in stable carbon isotope (δ 13 C) records with a negative carbon isotope excursion (CIE). The PETM CIE termination has been associated with a δ 13

Paleocene echinoid faunas of the eastern United States

, 2017
Twenty-one species of echinoid are reported from Paleocene rocks of the eastern United States along the outcrop belt from Texas to New Jersey. Six of these are strictly early Paleocene age (Danian), nine strictly late Paleocene age (Thanetian), five ...

Shifting Dietary Ecologies of Early Ungulates Across the Paleocene–Eocene Thermal Maximum in the Bighorn Basin, Wyoming

Ecology and Evolution, Volume 16, Issue 11, November 2026.
Understanding the interplay between climate change and ecology is crucial when attempting to reconstruct the evolutionary history of species. Here we use dental microwear texture analysis to infer the foraging ecologies of three lineages of early ungulates across the Paleocene–Eocene Thermal Maximum. We recovered differences in foraging guilds and only

Lower Paleogene Tectonostratigraphy of Balochistan: Evidence for Time-Transgressive Late Paleocene-Early Eocene Uplift

Geosciences, 2013
Analysis of lithofacies, paleoflow directions, and sandstone petrography of upper Paleocene-lower Eocene paralic and continental sediments exposed along the transpressional suture zone of the western margin of the Indian plate indicate that the process ...

Collocated Geotechnical and Geophysical Test Dataset at Three Sites in Napier, New Zealand

Earthquake Spectra, Volume 42, Issue 4, November 2026.
Reliable assessment of liquefaction hazard, particularly in the context of groundwater fluctuations associated with hydroclimatic changes and variability between liquefaction assessment methods, necessitates supplementary data and advanced site characterization methods.
