Paleontologists found a small theropod dinosaur skull right on top of a nest of eggs that were believed to belong to a plant-eating dinosaur. Instead of being the nest robbers that they were originally thought to be, raptors like this one would reveal themselves to actually be caring parents. Part of the "Eons" series.

Sea turtles have been around since the time of the dinosaurs, but today these beautiful creatures have many man-made threats from destruction of their beach habitat to marine debris and poaching. Conservation organizations, communities, and scientists are all working together to help sea turtles turn the tide. Part of the "Endangered Ocean" 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.
Edwina, the neighborhood dinosaur, plays with kids and bakes cookies. However, Reginald Von Hoobie-Doobie is determined to prove dinosaurs are extinct, but what will happen to Edwina if anyone believes him? Based on the children's book by award-winning author Mo Willems.
David Ray never turns his back on his research, and with good reason. Ray and his team study alligators, crocodiles, and bats. With support from the National Science Foundation, this multidisciplinary team from several universities is mapping crocodile and alligator genomes. Reptiles resembling these have existed for around 80 million years and they are among the first reptiles to have their DNA sequenced. The research will expand knowledge beyond crocodilians to other reptiles, birds, and even dinosaurs.
As shown on the History Channel. From Alaska to New Mexico, the Rockies are one of the great mountain belts of the world--caused by tectonic forces of the Pacific Plate pushing against the North American continent. They have formed as the earth's continental crust has been shortened under pressure, by around one inch a year. What's more, they are still rising and they are still young in geologic terms: when the dinosaurs roamed the Earth they had not even started to form.
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.
Timeblazers Jen and Sam travel back 63 million years before the first primitive people appeared on Earth, and they learn that people and dinosaurs never met. They jump to the Paleolithic age, when humans first appeared, to see some "cavemen," as they are often called. About 8000 BCE the first primitive civilizations began to develop after humans started farming. Then to 3100 BCE: The Egyptians. Around 750 BCE came the ancient Greek civilization; then from about 27 BCE to 476 CE came the Roman Empire. Then came the Middle Ages from 500 to about the year 1400, the Renaissance.
As shown on the History Channel. In the remote wastes of Siberia buried under snow are the remains of one of the greatest catastrophes that the Earth has endured. 250 million years ago, huge volumes of lava spewed out onto the surface--so much that it would have buried the whole of Texas under one mile of lava. At first the temperature dipped but then the greenhouse gases that escaped from the depressurized lava caused a massive global warming. It wreaked havoc, and 95% of the species on Earth became extinct. Yet life hung on and in time this disaster paved the way for the next phase of life on earth--the age of the dinosaurs.
