You are in the woodlands of Europe, 140 million years ago.

The rain slicked the windshield of your truck, creating a blurry, frantic world outside. Inside, your heart hammered against your ribs. It wasn’t because you had taken a wrong turn in the clearing of the forest.

You looked out by the windshield to see a massive dinosaur—a two-legged meat-eating dinosaur—standing silently nearby. Its distinctive, sail-like hump—jutting up ominously on its back—was instantly recognizable, dripping with water and mud.

The beast turned, its reptilian eyes locking onto your truck. There was no roaring, just a low, vibrating hiss that felt more terrifying than a scream.

You wonder, are you safe in the truck?
