Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

open access: yesThe Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

open access: yesThe Anatomical Record, EarlyView.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Integrated Electromagnetic Mapping Through K‐Means to Improve Identification of Areas of Archaeological Interest

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This study proposes a procedure to improve the interpretation of data from the Frequency Domain ElectroMagnetic method (FDEM), a geophysical technique with high benefit–cost ratios in archaeology. This method enables the simultaneous analysis of electrical and magnetic properties of the investigated medium, providing data as in‐phase and out ...
