Timeline
The timeline of dinosaur evolution spans over 160 million years, beginning in the Triassic Period and ending with their extinction at the close of the Cretaceous Period. Dinosaurs, which emerged from small reptilian ancestors, grew to dominate the Earth’s ecosystems, evolving into a diverse array of species ranging from towering herbivores to fearsome carnivores. Their evolutionary journey reflects a dynamic history of adaptation and survival, influenced by changes in climate, geography, and competition. This timeline offers a glimpse into the rise and fall of these magnificent creatures, whose legacy continues to captivate scientists and enthusiasts alike.
The story of dinosaurs is one of remarkable evolutionary success, marked by their dominance across three geological periods. From their humble beginnings in the Triassic to their peak diversity in the Cretaceous, dinosaurs adapted to various environments and challenges, becoming some of the most iconic creatures in Earth’s history. The sudden end of the dinosaur era, brought about by a catastrophic extinction event, serves as a poignant reminder of the fragility of life. Yet, the legacy of dinosaurs lives on, not only in the fossils they left behind but also in their descendants—modern birds—reminding us of the enduring impact of these ancient giants.
