Published: August 31, 2025

Duration: 2:55:48

Forests are among the most widespread and diverse biomes on our planet. This episode, we’re joined by our favorite paleobotanist, Dr. Aly Baumgartner, to explore what defines a forest, how these habitats function, and how they differ around the globe. Then, we’ll take a trip into the past to discuss how paleontologists study ancient forests and how these biomes have changed over hundreds of millions of years.

In the news: ocean sediments, early penguins, island foxes, Canadian dragonflies, and ancient deer.
