In recent years, there have been endless disaster films about crocodiles, which have deepened people's fear of crocodiles, and compared with the giant crocodiles that survived in ancient times, most of the crocodiles that exist on our earth today are small shrimp rice belonging to shrimp soldiers and crab generals, and their body size is really difficult to compare with prehistoric giant crocodiles. Today, I will give you a popular science, what kind of magical existence is the spiny crocodile as large as the baleen whale.
At the beginning of the last century, the German paleontologist Stemer, before the outbreak of World War 1, went to Egypt for an expedition, and in the process, he found a huge bone in the Baihariye oasis, and there are many huge fossils. He immediately sent these fossils to Germany, and later after the study of the fossils, he first named the famous spinosaurus, which is also the largest known carnivorous dinosaur, and among the many fossils, he also noticed a huge flat skull, after some careful study and consideration, he thought that this belonged to one of the prehistoric giant crocodiles, so he named it the spiny crocodile, which also means that the teeth in the crocodile's mouth have no lethality for other large organisms.
The spiny crocodile is a large prehistoric giant crocodile, although only its skull has been found, but according to the head of the crocodile today compared to biologists, its body length should be more than 10 meters, the weight of about 6 tons. It has a washboard face skull, like a long washboard, the shape looks very regular, a pair of eyes are growing on the head, its upper jaw has two rows, only 2 to 3 cm long small teeth, the jaw is very thin.
At its throat there is a super large skin sac similar to that of a pelican. Like the crocodiles that currently exist, it is bloated and has short limbs, a thick tail behind it, and a body full of hard bone pieces to protect it from other predators.
According to research and speculation, the echinococcosis crocodile lived in northern Africa 100 million years ago, and its habitat is located at a location where the sea routes meet. At that time, there were still various carnivorous dinosaurs on the earth, as well as large fish, reptiles and so on. Although the echinocostic crocodile is huge, it is actually a harmless existence for other large animals, when the large animals come to the water's edge and drink water, it will only lazily lie on the beach to bask in the sun, or hunt some small aquatic creatures in the water. It never rushes out like other aggressive giant crocodiles and drags large creatures into the water to hunt them.
Usually they like to swallow some small fish. Slowly advancing in the shallow sea, when it finds a school of fish, it will rapidly launch an upward impact from the bottom of the sea, and when it is close to the fish, it will open its large mouth like a washboard and suck the small fish into its mouth. At this time, the large skin sac of its jaw plays an extremely important role, it can accommodate a large number of small fish and seawater. After filling the large skin sac, it will discharge the seawater and eat the small fish and shrimp, which is very similar to the way baleen whales eat.
Although its size is more than 10 meters, it can be regarded as a prehistoric giant crocodile, but compared with those crocodiles with strong attack power, it is too unhurried, especially for ancient dinosaurs, such a spiny cavity crocodile does not actually pose any threat to them. Not only can they not pose any threat, but they are also easy to be attacked at an early age, because they do not have sharp teeth and amazing bite force, so when facing the attack of dinosaurs, they can only choose to escape, and only when they reach adulthood can they be large enough to ensure their own safety.
When the fossils of the spiny crocodile were studied and preserved in the museum, in World War 2, nearly a thousand Heavy Bombers from the United States bombed Munich in Germany, resulting in the destruction of the Biological Museum and the destruction of these precious fossils. Despite the continuous efforts and excavations of biologists and archaeologists, the fossils of the spiny crocodile could not be found again, and in this way, this prehistoric giant crocodile completely disappeared into the long river of history.
