ZZosterophylls 

Zosterophylls are an extinct group of early vascular plants that lived during the Silurian and Devonian periods. They are significant in paleobotany and evolutionary biology for their role in understanding the evolution of vascular plants, the transition from aquatic to terrestrial ecosystems, and the origins of modern plant lineages.

Hands holding a layered rock sample of manganese crusts

MArchives: Glossary

Manganese crusts are hard, layered deposits rich in manganese, iron, and other metals that form on the ocean floor, particularly on seamounts and ridges. These crusts are significant for their potential as a resource for critical metals and for studying the geochemical processes of the ocean.
