Discovering T. rex’s Origins
The T. rex we know today has fascinating roots. Recent research reveals that this iconic dinosaur evolved in North America from Asian ancestors. Scientists from UCL have uncovered how climate shifts and extinction events played a crucial role in the evolution of tyrannosaurids and megaraptors. These creatures adapted to their environments and increased in size over time.
This ancient migration was not a simple journey. The landbridge that connected Asia and North America allowed these prehistoric giants to traverse vast distances. The study highlights the impact of environmental changes on their evolution and spread across continents. As they adapted, they became formidable predators, shaping the ecosystems around them.
