The Perfect Snack from the Jurassic: How Baby Sauropods Shaped a Tiny But Mighty Food Web
Unearthing a Hidden Jurassic Menu When we think of the Late Jurassic, towering sauropods typically steal the spotlight. But beneath their colossal shadows, a more delicate drama played out on the forest floor: the predator-prey relationships that revolved around the smallest, most vulnerable diners of the time. Recent reconstructions of the Dry Mesa Dinosaur Quarry…

Life in fossil bones: what we can learn from tiny traces of ancient blood chemicals
Introduction: tiny traces, big revelations Fossil bones are more than long-dead skeletons. Within them lie faint chemical fingerprints—tiny traces of ancient blood components that survive for millions of years. By studying these remnants, scientists can infer physiology, diet, and even health patterns of creatures that no longer roam the planet. This field blends chemistry, biology,…

How Microbial Fossils Illuminate Life’s Origins in Earth’s Ancient Time
Setting the Stage: Earth’s Habitable Window in Deep Time More than 3.5 billion years ago, Earth was a world apart from today. The atmosphere lacked oxygen, oceans were acidic and iron-rich, and volcanic activity shaped a harsh, volatile landscape. Yet even in this extreme setting, life managed to emerge and leave traces that scientists can…
