Mass Dinosaur Grave Found in Canada's 'River of Death'

Imagine a giant graveyard of dinosaur bones!

Scientists found one in Canada called the 'River of Death.'

It’s packed with fossils of dinosaurs that lived 73 million years ago.

They think a flood killed a bunch of dinosaurs all at once.

This is super cool because it lets scientists study a whole group of the same kind of dinosaur together.

They can learn how the dinosaurs lived, how old they were, and if they hung out in herds.

It's like finding a whole dinosaur family frozen in time!
