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.

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.
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.
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.
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 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.
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.
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.
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 seafloor has a diverse landscape, which includes underwater lakes and rivers. How is that possible? Well, these lakes and rivers form when seawater seeps up through thick layers of salt, which are present beneath the seafloor. As the water seeps up, it dissolves the salt layer, causing it to collapse and form depressions. The dissolved salt makes the water denser, and because it is denser than the water around it, it will settle into the depressions, forming a river or lake. Part of the "Deep Sea Dive" 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.
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.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the three types of fossil fuels: coal, oil, and natural gas as well as their uses in modern society. Part of the Science Video Vocab series.
During prehistoric eras, the geography of North America was different. It was cut into by a large inland sea. In present day Utah, Paleontologists use guide fossils as they search for other fossils of ancient marine life. Ultimately, they hope to discover a fossil of Plesiosaurus. Segment of video from Wild Chronicles Series.
At Lake Seminole Farm, David Krause and Breck Dalton discuss mushroom production and their role in forest ecology. They grow organic shiitake and oyster mushrooms on trees found in the forest. Part of the "EcoAdventures in North Florida" series.
The geology of the Great Plains is a product of long periods of sedimentary buildup followed by equally long periods of erosion. The result today is a dramatic landscape of bluffs, pinnacles and badlands that contain the rich story, of ancient sea creatures, dinosaurs and long extinct, giant land mammals. The Agate Fossil Beds is a landscape that reflects many influences from early animals roaming the valleys and hills to tribal nations they call the High Plains home. Explorers passing through or settling the American West also have a part in the story.
Is a sixth mass extinction on the horizon? Dr. Anthony Barnosky and Kaitlin Maguire travel to the John Day Fossil Beds National Monument to find, collect, and date fossils. They have determined that the rate at which animals are going extinct today is much faster than normal.
Lucy was a hominid that lived 3.2 million years ago, and her anatomy provides surprising insights into human ancestors. A member of the species Australopithecus afarensis, Lucy illuminates the human evolution timeline. Students learn about this world-famous fossil and the evidence of bipedalism.
A documentary film highlighting recent and past USGS (US Geological Survey) research in the Lake Tahoe Basin. It features USGS science activities conducted by hydrologists, geologists, geographers, computer modelers, and biologists. Some of USGS science detailed includes water quality monitoring, streamgaging, and use of aerial photography. The use of consistent, reliable, long-term data and maps are crucial for evaluating and maintaining the lake and basin.
