The Cretaceous Period: The Dinosaurs’ Final Chapter
Step into the Cretaceous Period, the grand finale of the Age of Dinosaurs, which lasted from about 145 to 66 million years ago!
During this time, the world was buzzing with life, and dinosaurs like the enormous Triceratops, fierce Tyrannosaurus rex, and the armored Ankylosaurus roamed the land.
Flowering plants and colorful flowers started to bloom for the first time, making the world even more vibrant.
New kinds of birds soared above, while the oceans teemed with gigantic sea creatures and the first modern sharks.
Imagine a world where lush forests, buzzing insects, and some of the most famous dinosaurs ever to live created a scene straight out of a prehistoric adventure.
The Cretaceous was a time of amazing discoveries and dramatic changes, leading up to the end of the dinosaurs’ reign on Earth.
