True stories · Malta, Montana
The dinosaur mummy
Near the town of Malta, Montana, a fossil hunting team in 2000 uncovered something almost nobody expected to survive: a dinosaur with its skin still showing. The plant eater, a duck billed Brachylophosaurus nicknamed Leonardo, died about 77 million years ago as a young animal. Buried fast, more than 80 percent of its body was preserved as a natural mummy, with skin, scales, foot pads, and even the remains of its last meal in its stomach. Guinness World Records later listed it as the best preserved dinosaur ever found. Scientists scanned it like a patient, reading rare clues about how these animals truly looked and lived.

I am well known through the whole of Europe.

True stories · Lyme Regis, England
The girl who found sea dragons
On the cliffs of Lyme Regis, England, a young girl named Mary Anning hunted fossils to help feed her poor family. Her brother found an ichthyosaur skull in 1811, and Mary later excavated the rest of the skeleton, a dolphin shaped sea reptile from the age of the dinosaurs. In 1823 she found the first complete plesiosaur, a long necked swimmer so strange that experts at first doubted it was real. Self taught and rarely credited in her lifetime, Anning helped invent the science of paleontology. Today museums display her discoveries, and a statue in Lyme Regis honors the fossil hunter and her dog.
When the dinosaurs fell at the end of the Cretaceous, they were not a senile, moribund group that had played out its evolutionary options.
