Petrified Forest National Park in northeastern Arizona, USA is a hub for Triassic palaeontology and has exposures representing 20 million years of the Late Triassic Chinle Formation. Visitors marvel at the colourful fossilised trees from which the park takes its name, but a whole host of animals called these swampy forests home 225 million years ago.

In this episode, we talk to Dr. Adam Marsh, lead palaeontologist at the National Park. We explore the history, geology, and palaeontology of Petrified Forest, along with exciting research centred around specimens from the park. Research is ongoing, with many groups of palaeontologists working on Petrified Forest specimens, and we hear about directions it might go in the future.
