You are in the forested floodplains of China, Asia, 75 million years ago.

The air in the Late Cretaceous was thick and humid, smelling of damp ferns and the nearby lake. You were kneeling near the lake, documenting fossil fragments, when a low, vibrating hum resonated through the air—like a deep, guttural tuba sound.

You froze, looking up toward the treeline. Emerging from the lush green foliage, a Tsintaosaurus stepped into the clearing.

It was roughly 27 feet long, moving mostly on four legs, though it paused to rear up on its hind limbs to browse from the higher branches. What held you captivated was the head. The strange, singular, spike-like crest projected forward and upward, looking exactly like the "unicorn" snout from my early research. It was bizarre and beautiful, far more intimidating in person than in illustrations. As it nibbled on vegetation, the crest seemed to amplify its breathing, producing that haunting, resonant call again.

It noticed you then, pausing its feeding to look over with a gentle, dark eye. For a moment, you just stared at each other. It didn't feel dangerous, only deeply curious—a gentle "duck-billed" giant, thriving in its world.
