PBS Eons: There's An Invisible Ocean Between These Fossils #fossils #paleontology #geology #platetectonics #trilobites

There's a new episode of PBS Eons.  This one is about trilobites and what they show us about the history of the Earth's continents.

This is the hundred-year tale of how an unlikely bunch of bottom-dwelling marine critters helped reveal that ocean basins are basically reincarnated every few hundred million years.
