An Unusual Occurrence of Nautilus macromphalus in a Cenote in the Loyalty Islands (New Caledonia)

PLoS ONE, 2014
Exploration of a landlocked cenote on Lifou (Loyalty Islands) revealed 37 shells of the cephalopod Nautilus macromphalus Sowerby, 1849, in saltwater on the cenote floor, approximately 40 m below the water surface. The occurrence of these shells is unusual because N. macromphalus is restricted to the open marine waters surrounding the island. All of the

Exploring the origins of magnetization within the Chicxulub crater upper peak ring

Meteoritics &Planetary Science, Volume 60, Issue 4, Page 823-848, April 2025.
Abstract Large terrestrial impacts may produce vast subsurface hydrothermal systems, capable of generating conditions favorable to the origin of life. Modeling suggests that these systems may persist for >1 million years for basin‐sized craters; however, direct experimental constraints on hydrothermal system duration are needed.
