What are Some Animals that Lived in Pleistocene Australia?

Reptiles are the most striking group of all paleontology. This is because reptiles were once the most successful animals in the history of the earth. It is because the end of the reptile era is related to a mass extinction that cannot be explained now, giving people a sense of mystery.

The early non-porous and double-porous species were small animals the size of ordinary lizards, but the lower-porous species were larger, up to 3 meters in length. After entering the Permian, reptiles evolved rapidly. Although this era has not yet been called the reptile era, the prosperity of reptiles is no less than amphibians. In the early Permian, the lower foramen were primitive Panosaurus. Among them, the huge carnivorous allosaurus Dimetrodon (pictured left) and the huge plant-eating kimono dragon Edaphosaurus have huge sails on their backs, which may regulate body temperature. related. The lower perforations in the late Permian were beast holes, which were very diverse. They were the dominant animals of the time, including the largest animals on the Permian land, and some smaller members, some were carnivorous. Others are herbivorous, and some members already possess many similar characteristics to mammals. The Permian non-porous species mainly include the two groups of cuposaurus and middle dragon, and there are also uncertain ancestral types of turtles. There are many species of cuposaurus, both members of the carnivorous and plant-eating groups, and the medium dragons are small aquatic reptiles, which are widely distributed and are used as evidence of continental drift. There are not many significant representatives of the Permian biporous species. It is worth mentioning that Coelurosauravus (pictured right), which has a skin similar to a modern flying lizard on the body side, can glide in the air, although it is not a true flight. , But this is the first time a reptile has entered the sky. At the end of the Permian, the world experienced the largest extinction of biology. Many old taxa were declared extinct, while many exciting new taxa waited on the historical stage.

The Triassic was the real beginning of the reptile era. At this time, the primordial dragons on the land and the pores in the oceans stepped on the historical stage and thrived. The emergence of pterosaurs in the dragons at the beginning of the period announced that the reptiles had begun a complete rule of sea, land and air. In the Triassic, the beast holes continued to develop and eventually evolved into mammals, but they were suppressed by the protosaurians.

Cenozoic reptiles are generally similar to modern types, but there are a few species worth mentioning. In the Tertiary period, a group of crocodiles, which are inclined to live on land, was called Xibei. Their teeth have similar characteristics to carnivorous dinosaurs. Some people originally thought that some dinosaurs had survived to the Cenozoic. At the time of the Pleistocene, Australia had a large class of giant lizards, much larger than Komodo Dragon, the largest modern lizard. They were Australia's largest carnivores at that time. They did not declare extinction until very late. Extinction may be related to the arrival of humans.
