    In the mid-to-late 20th Century, dinosaurs received a major makeover in their scientific and popular image. This episode, Riley Black takes us through the timeline of the Dinosaur Renaissance. We discuss some of the big scientific milestones and the various players which brought dinosaurs into their modern era, and we’ll explore the early signs and lingering notes of this historic shift.

    In the news: sleepy jellyfish, fast mammals, bird beaks, and dinosaur diets.

    This episode, we set our sights on the Diving Pokémon. How might evolution produce a sea-dwelling bird with a knack for stirring up storms? Our creature to create this time: Lugia.

  • Episode 236 - Chalicotheres
    Feb 1 2026

    The Cenozoic Era was home to many unusual ancient mammals, but few so strange as the “gorilla-horses,” the ungulates that swapped their hooves for claws, chalicotheres. This episode, we discuss the features that make these animals distinct and which confused paleontologists for decades, and we go over what is known – and still unknown – about their evolution and lifestyles.

    In the news: Let’s Botanize, Prototaxites identity, and giant kangaroos.

  • Episode 235 - Aquatic Plants
    Jan 18 2026

    All plants need water, but some take it to the extreme. This episode, Dr. Aly Baumgartner joins us to explore the many life strategies of plants that live in the water. We’ll discuss the adaptations that allow them to lead an aquatic lifestyle, their evolutionary history as seen through genes and fossils, and the benefits that keep leading plants back to water.

    In the news: fish diversity, ammonite survivors, gut microbes, and hiding dinosaurs.

This episode, we’re joined by special guest Brandon Strauss to discuss the distinctive anatomy and varied habits of flies, mosquitoes, and their many two-winged relatives. Then, we’ll peer into the past for a glimpse at the fossil record and dynamic evolutionary history of the group.

    In the news: long-nosed crocs, river mosasaurs, stampeding sea turtles, and giant snakes
