Just about every body of water on Earth, from oceans to puddles, is home to an ecosystem of tiny drifting organisms. This episode, we discuss what sorts of organisms we might expect to find in a swarm of plankton, we’ll explore how plankton is so fundamental to biological and geological systems on Earth, and we’ll take some time to lay out some of the many ways that ancient plankton are a crucial part of the fossil record.
In the news: climbing reptiles, croc extinctions, Ashfall rhinos, and ankylosaur tracks.
