The Mesozoic Era, spanning approximately 180 million years from the late Triassic to the end of the Cretaceous period, is often called the "Age of Dinosaurs." During this time, dinosaurs rose to dominance, becoming the Earth's most formidable creatures. These fascinating beings thrived in various forms and sizes, ranging from the massive Argentinosaurus to the agile Velociraptor. Understanding where dinosaurs lived and how they distributed themselves globally provides crucial insights into their evolution, behaviour, and eventual extinction.

The study of dinosaur distribution is significant for multiple reasons. It helps palaeontologists piece together the puzzle of Earth's prehistoric environment and climate. Moreover, it sheds light on the patterns of migration, adaptation, and survival strategies employed by these ancient giants. This blog will explore the global distribution of dinosaurs, examining the impact of continental drift and the fossil evidence found on each continent.

At the dawn of the Mesozoic Era, all of Earth's landmasses were joined together in a supercontinent known as Pangaea. This massive landmass began to break apart during the late Triassic period, leading to the formation of the continents as we know them today. The breakup of Pangaea played a pivotal role in the distribution and evolution of dinosaurs.

As Pangaea split into separate continents, populations of dinosaurs were isolated from one another. This isolation led to distinct evolutionary paths, resulting in the diverse array of dinosaur species discovered today. The breakup also created different climatic zones, further influencing the habitats and lifestyles of dinosaurs. For instance, some regions became lush and tropical, while others turned into arid deserts or temperate forests, each supporting different types of dinosaur life.
