How the Sima de los Huesos was won
The Anatomical Record, Volume 307, Issue 7, Page 2225-2245, July 2024.Abstract Although the first discovery of a human fossil in the Sima de los Huesos took place in 1976, systematic excavations did not begin there until 1984. Since then, this site has been continuously excavated in month‐long camps. The site is dated by different radiometric techniques to between 430,000 and 300,000 years ago.

Magmatic Storage and Volatile Fluxes of the 2021 La Palma Eruption
Geochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.Abstract The 2021 La Palma eruption (Tajogaite) was unprecedented in magnitude, duration, and degree of monitoring compared to historical volcanism on La Palma. Here, we provide data on melt inclusions in samples from the beginning and end of the eruption to compare the utility of both melt and fluid inclusions as recorders of magma storage.
