Seventy million years before the first bird took flight, a small dinosaur curled into the same sleeping posture a duck assumes today — and was preserved that way in the Gobi Desert long enough for us to find it. The newly named Jaculinykus yaruui, an alvarezsaurid no larger than a house cat, offers the first definitive fossil evidence that birdlike thermoregulatory sleep behavior evolved in non-avian dinosaurs well before powered flight emerged. Its discovery gently erases another boundary we had drawn between dinosaurs and birds, reminding us that evolution does not honor the categories we im

Narrative dramatization combined with scientific reporting. The article opens with vivid storytelling ('Death in the wild is often brutal and violent. But for one small, birdlike dinosaur...the end of its life was relatively peaceful') to engage readers emotionally before transitioning to factual scientific details. This creates accessibility rather than distortion.
