How Dinosaurs Died: New Evidence in the PBS Documentary
Thescelosaurus walked stealthily along the beach. The massively muscled dinosaur
which measured approximately 12 feet long and weighed about 500 pounds, could have been seeking for food — or trying to avoid becoming a meal.
Thescelosaurus swayed on two legs, the greater half of its body tilted, with prominent bony eyebrows and a pointed mouth
The long tail reaches back to provide balance. The dinosaur raised its head and peered about, startled by the sudden quiet that had broken a chain of terrifying natural forces.
As the waters in the neighbouring sea rushed in response, the ground began to tremble violently. Burning embers floated down from the sky and set fire to the lush primaeval woodland.
Thescelosaurus became agitated and attempted to flee, but it was too late
Everything changed in an instant when a 30-foot surge of mud and debris slammed into the sea channel from the south, shredding lives and limbs
The dinosaur was swept away by a massive flood, and the impact tore its leg from its hip.
A spectacular fossil discovered last year at the Tanis dig site in North Dakota captured that moment 66 million years ago, at the end of the Cretaceous period
when an Earth-shattering asteroid terminated the reign of the dinosaurs. The skin, muscles, and bones of the three-toed Thescelosaurus are vividly visible in this wonderfully preserved leg.
While the details of the death scenario mentioned above have been enhanced, they are based on interesting new discoveries and estimates by Tanis' chief palaeontologist, Robert de Palma.
