This giant frog weighs about 4.5 kilograms and is 40.6 centimeters long. Scientists named this strange ancient giant frog "Devil Frog". They concluded that this giant frog lived in the late Cretaceous about 70 million years ago and was contemporary with dinosaurs. Scientists believe that it can even swallow newly hatched dinosaurs. The largest frog in the world is the "Giant Frog" in West Africa, weighing about 3 kilograms.
Chalk thorn shark
Chalk spiny shark is a top marine predator, known as the "throat of Cretaceous", and its size is similar to that of great white shark. It is more than 7.6 meters long, and its tail accounts for half of its body. It swims with its undulating body and flippers at the same time, and dares to attack the little hidden dragon, similar to the situation that the great white shark dares to attack the little sea lion or seal.
