"Unveiling the Ancient 'Blue Dragon': Japan's Terrifying Prehistoric Sea Predator"

Scientists have discovered the Wakayama Soryu, a giant aquatic lizard that dominated the Pacific seas 72 million years ago. As big as a Great White Shark, this unique creature had four large flippers and a dorsal fin, making it different from other mosasaurs. The most complete mosasaur ever found in Japan, the Wakayama Soryu had rear flippers larger than its front and used its large front fins for rapid maneuvering. Its massive tail provided acceleration, making it a deadly predator. This discovery challenges our understanding of how mosasaurs swam and sheds light on the prehistoric marine ecosystem.
