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.

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.
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.
The colorful rock formations at John Day Fossil Beds preserve a world class record of plant and animal evolution, climate change, and ecosystems that span over 40 million years. With over 10,000 square miles of land, visitors can explore the prehistoric past of Oregon and see the impact of geologic forces on earth’s landscape.
Dr. Scott Wing spent a decade combing the hills in the Bighorn Basin of Wyoming to find fossil evidence of an extinction event that occurred in the Southern Ocean of Antarctica around 56 million years ago. In this episode, host Emily Graslie talks with him and Dr. Kirk Johnson about how studying the fossil record helps scientists better understand climate change. Part of "The Brain Scoop" series.
Paleoanthropologist Dr. Tim White discusses how his team unearthed the fossil of Ardipithecus ramidus, an early hominid that lived about 4.4 million years ago. Dr. White discusses the fossil record and hominid evolution.
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.
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.
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.
Before the start of the Eocene Epoch about 56 million years ago, Antarctica was still joined to both Australia and South America. During this time, Antartica was without ice and snow. Fossil records indicate it was covered in green foliage. Part of the "Eons" series.
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.
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.
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.
Host Emily Graslie takes the fish fossils she found at Fossil Lake back to the museum. She works with Akiko Shinya, who is a fossil preparator, to prepare the fossils for exhibition. Part of "The Brain Scoop" series.
Fossils are windows to the past. This program takes a look at how fossils are formed and preserved. Special attention is given to the meaning, significance, and use of fossils in telling about past life on Earth.
Uses trilobite fossils as an example to illustrate the challenges scientists face in understanding the prehistoric world and its place in time. Examines fossil sites in Australia, discusses how fossils are formed, and tells how a fossil's world is recreated.
Some of the world's best preserved fossils are found in the flat-topped ridges of southwestern Wyoming's cold sagebrush desert. Fossilized fishes, insects, plants, reptiles, birds, and mammals are exceptional for their abundance, variety, and detail of preservation. Most remarkable is the story they tell of ancient life in a sub-tropical landscape.
Hagerman Fossil Beds National Monument in Idaho is home to over two hundred different species of fossil plants and animals: including saber tooth cat, mastodon, bear, camel, ground sloth, and many other species. Over 3,000 new fossil fragments are found each year.
Host Emily Graslie travels to Fossil Lake in Wyoming. In this episode, she learns the history of Fossil Lake from Lance Grande, who is the Negaunee Distinguished Service Curator at The Field Museum. Fossil Lake is home to the largest complete representation of early Eocene life in the world. Part of "The Brain Scoop" series.
The age of dinosaurs comes alive as viewers take a trip back in time. Students will discover how fossils are formed and come to understand that fossils can provide clues about how dinosaurs lived and died. Part of the Real World Science series.
