  • Person holding a fossil of a spiral shaped animal. Caption: Hildoceras bifrons is an extinct species of ammonite

    Host Emily Graslie explores myths surrounding the discovery of fossils. Did the discovery of Protoceratops fossils give birth to the stories about griffins? Another mythical creature, the Cyclops, also has potential ties to the fossil record. Is an extinct species of ammonite actually serpents turned into stone? Part of "The Brain Scoop" series.

  • Illustration of a giant shark dwarfing the whales it swims with and is about to bite into one. Caption: megalodon was maybe 50 feet, or 15 meters, in length.

    When scientists attempt to study prehistoric sharks, they typically only find their teeth. Since the teeth are the only fossil records, they are left to imagine what these creatures looked like. In this episode, host Emily Graslie highlights some of the teeth of prehistoric sharks. Part of "The Brain Scoop" series.

  • The sculpture, of a dragon sprawled, at the steps of Kinh Thien palace. Caption: Remains of Kinh Thien Palace.

    People have been discovering the traces and remains of prehistoric creatures for thousands of years. They have also probably been telling stories about fantastic beasts since language became a thing. Is it possible that the monsters that populate myths and legends were influenced by the fossil record? Part of the "Eons" series.

  • An illustration of a male Woolly mammoth.

    Woolly mammoths disappeared from Europe and North America at the end of the last Ice Age, about 10,000 years ago. This episode sets out to solve one of the mysteries about these charismatic megafauna: why do most remains of mammoths found in the fossil record turn out to be male? Part of the "Eons" series. Please note this title discusses animal reproduction.

  • Person speaking. Caption: Well, today we're gonna talk about mammalian diversification.

    Host Emily Graslie discusses a new scientific theory about mammalian diversification. According to this new theory, placental mammals evolved before a major mass extinction event, which occurred sixty-five million years ago. However, there is no fossil record to prove the new theory, but scientists around the world used genetic material to form their theory. Part of "The Brain Scoop" series.

  • Illustration of a primate standing on two legs. Caption: Ardi is neither a chimp nor is she a human.

    Paleontologists have studied the fossil record of human evolution just like they have done for other major transitions, including the evolution of tetrapods from fish and the evolution of birds from dinosaurs. Sean Carroll and Tim White discuss the most important human fossils and how they illuminate key phases of human evolution, focusing in particular on three traits: larger brains, tool use, and bipedality.

  • Two almost identical fish. One is larger and has an extra fin on the bottom of its body. Below each fish is a strand of DNA with the same section highlighted. Caption: changes in form are ultimately due to changes in genes.

    After the end of the last ice age 10,000 years ago, populations of marine stickleback fish became stranded in freshwater lakes dotted throughout the Northern Hemisphere in places of natural beauty like Alaska and British Columbia. These little fish have adapted and thrive, living permanently in a freshwater environment drastically different than the ocean. Stickleback bodies have undergone a dramatic transformation, some populations completely losing long projecting body spines that defend them from large predators. Various scientists, including David Kingsley and Michael Bell, have studied living populations of threespine sticklebacks, identified key genes and genetic switches in the evolution of body transformation, and even documented the evolutionary change over thousands of years by studying a remarkable fossil record from the site of an ancient lake ten million years ago.

  • Person holding the fossilized skull of an animal. Caption: but there's still a liveliness and a connection

    The American Museum of Natural History has more than 33 million artifacts and specimens in their scientific collections. This episode provides an overview of the various objects found in the museum. Some are centuries-old specimens, while others are entirely new types of specialized exhibits. However, the entire collection is an irreplaceable record of life on Earth. Part of the "Shelf Life" series.

  • Fossilized remains of the skull of an animal with large teeth. Caption: from the evidence they left behind.

    Students learn why fossils are often referred to as "windows to the past." The basic requirements for fossil formation are identified. Examples of various fossils highlight different types of fossil preservation, including petrification, imprints, molds and casts, freezing, amber fossilization, and preservation in tar pits. Finally, various uses of fossils are discussed. Additional terminology and concepts: cement, paleontology, fossil fuels, preserved remains, paleontologist, sediments, and limestone.
