Dinosaur Timeline takes you on a journey across deep time, revealing how dinosaurs emerged, evolved, and ultimately vanished from Earth in one of the most dramatic chapters in natural history. This section of Dinosaur Street explores the prehistoric eras that shaped dinosaur life, from their early beginnings in the Triassic Period to their global dominance during the Jurassic and their astonishing diversity in the Cretaceous. Rather than viewing dinosaurs as creatures frozen in time, Dinosaur Timeline shows how they adapted to shifting continents, changing climates, and evolving ecosystems over millions of years. You’ll discover how small early dinosaurs rose alongside ancient reptiles, how giant plant-eaters transformed landscapes, and how powerful predators evolved to rule their environments. The timeline also explores the slow build-up to extinction, separating scientific evidence from popular myths about what truly ended the Age of Dinosaurs. Designed as a foundation for deeper exploration, Dinosaur Timeline helps readers understand not just when dinosaurs lived, but why each era mattered, turning prehistoric time into a clear, fascinating story of survival, transformation, and loss.
A: Dinosaurs rise in the Triassic, rule through the Jurassic, diversify in the Cretaceous, and most die out at ~66 mya.
A: Both refer to “million years ago”; scientists often use Ma in geologic charts.
A: Layer relationships + index fossils + radiometric dates from nearby volcanic material.
A: No—non-bird dinosaurs vanish ~66 million years before humans appear.
A: Yes—birds are living theropod dinosaurs and continue the lineage today.
A: Certain environments bury remains quickly—floodplains, river deltas, and ash-rich regions preserve more.
A: Different ages and ecosystems—many famous “dino icons” (like T. rex and Triceratops) are Cretaceous.
A: A major impact event and cascading climate/ecosystem collapse ended most dinosaur lineages.
A: New fossils and improved dating methods refine the timeline and family tree.
A: Learn the era (Mesozoic) and the three periods (Triassic/Jurassic/Cretaceous), then zoom into key events.
