🌍 Welcome to WikiPaleo: Exploring the Upper and Late Cretaceous World

WikiPaleo is our dedicated knowledge space where science meets adventure — a window into the ancient oceans and continents of the Upper and Late Cretaceous, the final chapters of the Age of Dinosaurs.

Here, we dive deep into the prehistoric ecosystems that shaped life as we know it. From marine reptiles like the powerful Mosasaurus and graceful Plesiosaurs, to the colossal dinosaurs that ruled the land such as Tyrannosaurus rex, Triceratops, and Hadrosaurs, WikiPaleo uncovers the fascinating stories of creatures that lived over 66 million years ago.

🌊 Life Beneath the Ancient Seas

The Late Cretaceous oceans were home to a diversity of marine giants — mosasaurs, ichthyosaurs, ammonites, and early sharks that dominated the deep. These waters were warm, shallow, and teeming with life, forming complex food webs that scientists are still uncovering through fossils and sediment studies.

🦕 Giants of the Land

On land, the planet was a mosaic of lush forests, flowering plants, and dramatic volcanic landscapes. Towering dinosaurs roamed North America, Europe, Africa, and the southern continents, evolving into specialized forms just before their sudden extinction at the end of the Cretaceous.

☄️ The End of an Era

The Upper Cretaceous marks not only the peak of dinosaur evolution but also their dramatic fall. Around 66 million years ago, a catastrophic asteroid impact changed Earth’s climate, wiping out nearly 75% of all species — yet paving the way for the rise of mammals and birds.

📚 Our Mission

WikiPaleo brings together research, fossil discoveries, and scientific insights to make the Cretaceous world accessible to everyone — from enthusiasts to students and researchers. Each article is designed to educate, inspire curiosity, and celebrate the remarkable diversity of life that once thrived in Earth’s ancient past.
