Scientists believe they have discovered a fossilized time capsule from the exact day when Earth transformed from being a verdant, dinosaur-ridden world to a soot-covered apocalyptic hellscape. Within that time capsule was a very well-preserved dinosaur leg from a dinosaur that scientists believe died that spring day, some 66 million years ago.
The discovery, which was made at the Tanis dig site in North Dakota, will be discussed in more detail in a BBC documentary narrated by David Attenborough titled "Dinosaurs: The Final Day." A version of the documentary will be broadcast on PBS in the United States next month. While the findings have yet to be published in a peer-reviewed scientific journal, scientists are very excited about the discovery and the prospect of what information it might hold.
