Episode 48 - Sharks

This episode, it’s back into the ocean, this time to discuss one of the most successful groups of predators on the planet. Sharks are famously “ancient,” but their evolutionary story is complex and fascinating, stretching back more than 400 million years, from their assorted bizarre ancestors to the incredible diversity we see today.

In the news: nocturnal elephant birds, hadrosaur sounds, prehistoric protein preservation, and colorful dino eggs.
