What are giant amphibians?
Today is most amphibians - such as frogs, toads, registers and registers - relatively small, usually below 18 cm (7 inches) size. The largest living amphibian, the Chinese giant salamander, is significantly larger and can move up to 1.83 m (6 ft). However, this is very atypical for modern amphibians. This time, when amphibians first evolved, in the late Devonian/early carbon, about 360 million years ago. Giant amphibians had their Heydey in the carbon and began to experience a decline in early permia when larger and better reptiles such as pelycosaurs developed. They almost died out to extract Permian-Triassic 251 million years ago, but survived in small pockets in what Australia and Chinaeah are now 120 million years ago. Today, only Lissamphibia is alive. There are many debates on whether modern amphibians have evolved from one of these ancient groups or independently gained their modern qualities.
SomeoneThe sole giant amphibians were called "killers" because of their superficial similarity to modern newts. The group, which included all giant amphibians, labyrinthodontia, is thus named because their teeth are reminiscent of their teeth labyrinth. The largest labyrintodons were called the Temnosponyls, which divers you want to fill many empty earthly niches. The most common body plan for these animals was a very large lizard with large legs and excessive head and jaw. Some had long, slim bodies and others had short, hard bodies.
Most giant amphibians were between 2 and 4 meters in length, although some, like prionosuchus , was up to 9 m (30 ft), the largest amphibian ever to live, and would be one of the largest complex animals at that time. This giant amphibian showed a large degree of convergence with a crocodile that was superficially resembling.
