Tiny Glass Beads Suggest the Moon Had Active Volcanoes When Dinosaurs Roamed Earth NEW YORK (AP) — Volcanoes were still erupting on the moon when dinosaurs roamed Earth, new research suggests.

“We combined a wide range of microscopic analytical techniques, numerical modelling, and geological surveys to determine how these microscopic glass beads from the Moon were formed and when ...

"These high-magnesium glass beads may have formed when an asteroid smashed into rocks that originated from the mantle deep within the moon," Professor Nemchin said. "This is exciting, because we ...
