【Science and Technology News】On April 20, 2016, the devil frog ate the Tyrannosaurus Rex scene horror, prehistoric monster rankings. Prehistoric behemoths appeared in the rankings of animals stronger than Tyrannosaurus rex, devil frogs and Jurassic dinosaurs are an era, scientists have a bold speculation after the study of devil frogs, scientists speculate that in the Jurassic era devil frogs can swallow dinosaurs, is this true? Science and Technology News Xiaobian takes you to take a look at the prehistoric behemoth rankings.
We all think that the Tyrannosaurus rex is the strongest among the prehistoric behemoths, but in fact, there are many prehistoric behemoths that we have not heard of, in fact, they are stronger than the dragon I have, and the devil frog is one of them. Scientists believe that the devil frog could swallow a newly hatched Tyrannosaurus rex.
1. Devil frog found on the island of Madagascar
Klaus, a paleontologist from the State University of New York in the United States, and others found a fossil giant frog on the island of Madagascar, which weighs about 4.5 kilograms and is 40.6 centimeters long. Scientists have named this strange ancient giant frog "Devil Frog". They deduced that the giant frog lived about 70 million years ago in the late Cretaceous period, at the same time as the dinosaurs. Scientists believe it could even swallow small dinosaurs that have just hatched. The largest surviving frog in the world is the West African "giant frog", which weighs about 3 kilograms.
According to National Geographic magazine, we all know that dinosaurs are very large, but we don't necessarily know rats as big as bulls, marine scorpions taller than humans, giant frogs as big as balls, penguins as big as small adults, marsupials that resemble lazy people, and sharks that are more than 15 meters long and more than 30 times heavier than modern great white sharks. These megafauna have all existed, but at different times and places.
2. The largest snake fossil was found in the Colombian coal mine
An international team of researchers has speculated based on fossil snake skeletons unearthed in northern Colombia that a giant snake that lived in the tropical region of South America 55 million years ago may be the longest species of snakes known to researchers. The researchers named the giant snake Titanobooa cerrejonensis. Scientists at the University of Florida and the Smithsonian Institute for Tropical Research in Panama have used computer mathematical models to speculate that the ancient giant snake is at least 13 meters long and can weigh 1.135 tons. Currently, the Green anaconda is the world's heaviest snake, but it weighs only 250 kilograms. The site of the giant snake fossil excavation also excavated the skeleton fossils of giant turtles and ancient crocodiles, which researchers speculate may be the prey of the giant snake. The researchers point out that the snake is a cold-blooded animal whose body size is greatly affected by the outside temperature. The size of the ancient serpent described above suggests that the equatorial region of South America may have been hotter than it is now 55 million years ago. Researchers speculate that 60 million years ago, the average annual temperature in the equatorial region of South America might have reached about 32.8 degrees Celsius.
3, the giant marine scorpion is bigger than a human
An international team of geologists and archaeologists say they have found an ancient marine scorpion in Germany, which is taller than a human, 2 meters 5 meters long, and the claws alone are 47 centimeters long. Fortunately, it was extinct 390 million years ago, otherwise humanity would be seriously threatened. In addition to its sheer size, this marine scorpion also has the appearance of a modern scorpion, living in the salt water of the ocean and the fresh water of lakes and rivers, about 460 million to 255 million years ago. This marine scorpion has a shell of armor and a huge body, indicating that they were once the king of the animal kingdom, located at the top of the food chain, eating fish and trilobites, and even cannibalizing each other. They generally live in the water, sometimes walking on 6 legs on the bottom of the sea, while a pair of hind legs become paddles for parade. They protect themselves with a hard shell, otherwise they are vulnerable to attack by their opponents. They may also wait until their new shell hardens before mating.
4. Tyrannosaurus rex, also known as Tyrannosaurus rex, scientific name Rex Tyrannosaurs.Rex, meaning brutal lizard king. It is one of the most recent species of dinosaurs to appear, with an average body length of 11.7 meters, a maximum length of 14.6 meters, an average hip height of 4 meters, a maximum hip height of more than 5 meters, an average weight of 11 tons, and a maximum weight of 14.85 tons, which is one of the largest carnivorous dinosaurs and one of the largest theropod dinosaurs. The Maastricht Order, which lived at the end of the Cretaceous period, is about 68 million to 65 million years old at the end of the Cretaceous period, and was one of the last dinosaurs before the Cretaceous-Tertiary extinction event. The fossils are found in the United States and Canada and Mexico in North America, and are more widespread than other tyrannosaur families
5. Southern Behemoth Dragon
Southern Megalopodosaurus was one of the largest terrestrial carnivorous dinosaurs, and the Southern Megalopoda was very similar to their close relative, Mapplex, which was longer than Tyrannosaurus rex, but slightly lighter than T. rex, and was one of the largest carnivores, with an average body length of 14 meters, an average height of 5 meters, and an average weight of 11 tons. The first fossil of a behemoth dragon was discovered in 1993 by an auto mechanic named Ruben Garolini. The behemoth dragon walks on two legs. Its large mouth has a mouthful of sharp teeth, and the largest sharp teeth are 30 cm long. As a descendant of Allosaurus, the Southern Megalopods evolved even more massively, being the largest carnivorous dinosaur besides Spinosaurus, with robust forelimbs more suitable for hunting other dinosaurs than Tyrannosaurus rex and a tail thick and pointed enough to knock prey unconscious. With an extremely frightening bite force and extremely fast tearing speed and sharp teeth like a dinner knife, the bite force can reach 16,000 N. Among terrestrial animals, the southern giant beast dragon has the second largest bite force after Tyrannosaurus rex, and is the second largest terrestrial carnivore with the bite force.
6. Allosaurus
Allosaurus, also known as " Orthosaurus " , is a genus of dinosaurs of the theropod suborder Carnithischia. Allosaurus was a large bipedal, predatory dinosaur with an average length of 10 meters and a maximum length of 12 to 13 meters, making it the seventh largest carnivorous dinosaur, slightly smaller than Spinosaurus, Megalopodosaurus, Tyrannosaurus rex, Mapurus, Sharktooth, and Tyrannosaurus rex. They lived in the Late Jurassic Period, between 155 million and 145 million years ago. Since being named by Othniel Charles Marsh in 1877, there have been many possible species classified in the genus Allosaurus, but only a few are considered effective species.
7. Crocodiles:
The crocodile ( scientific name : Deinosuchus ) is an extinct macrocoscillum belonging to the alligator superfamily that lived on the eastern coast of North America during the late Cretaceous period. The genus name of the crocodile means "giant crocodile of terror" in Greek, δεινός/deinos means "terror", and σουχος/suchos means "crocodile".
Crocodiles are one of the largest crocodiles ever seen and may have fed on dinosaurs. The fossils of crocodiles found so far are mainly skulls. According to recent studies, paleontologists' estimates of the length of crocodiles are shorter than previous estimates. Since the fossils of crocodiles are quite fragmented, there are currently considerablely different estimates of the length of crocodiles. In 1954, Edwin Harris Colbert and Roland T. Bird estimated the jaw length of the crocodile to be 2 meters, and compared it with other large crocodiles, proposed that the crocodile was 15 meters long. In 1999, Gregory M. Erickson and Christopher A. Brochu proposed a shorter version, arguing that crocodiles were 8–10 meters long. In 2002, David Schwimmer proposed that the crocodile living in eastern North America is 8 meters long and weighs 2 tons; The crocodile, which lives in western North America, is larger, 12 meters long and weighs 8 tons.
