[Science Dream books] https://www.amazon.co.jp/dp/4847073444 The Mesozoic era was filled with reptiles everywhere, whether it was in the sky, land, or sea. The era of reptiles, which seemed to continue forever, came to an end 66 million years ago when a meteorite fell on the Yucatan Peninsula. Then, mammals followed them, and the Cenozoic era was truly the era of mammals. In fact, the number of mammals in North America, which was only 18 genera in the Mesozoic era, increased to 84 genera in the middle Paleocene epoch of the Cenozoic era, showing how quickly mammals multiplied. However! During the Pleistocene epoch of the Cenozoic era, which was the golden age of mammals, there were reptiles throughout Australia that were still enjoying their past glory. It's a gigantic lizard called Megalania, with a body that can grow up to 5m in length and sharp teeth! ================================= [Reference materials] ▶Books The Bare Bones: An Unconventional Evolutionary History of the Skeleton (Life of the Past) Dragons in the dust: the paleobiology of the giant monitor lizard Megalania, Molnar, Ralph E.
