Unveiling the Secrets Behind Dinosaurs' Gigantic Size
Researchers at the State University of Campinas in Brazil have discovered that air sac structures in the ancient dinosaur Macrocollum itaquii played a crucial role in the evolution of dinosaurs. These air sacs, similar to those found in modern birds, allowed dinosaurs to capture more oxygen, regulate body temperature, and survive harsh conditions. The presence of air sacs gave dinosaurs an evolutionary advantage, enabling them to grow into massive creatures like the Tyrannosaurus rex and Brachiosaurus. The study challenges previous assumptions about air sac evolution and sheds light on the remarkable diversity of dinosaurs during the Jurassic and Cretaceous periods.
