Prehistoric dinosaur frog really eat?

To review of surviving animals on earth which only the largest and most ferocious, I believe many people will choose without hesitation "dinosaurs." Dinosaurs ruled the Earth 160 million years, it is a veritable land overlord, almost no natural predators. Surprisingly, however, scientists at the University of Adelaide in Australia recently published paper points out in "Science Report": There is a giant frog living in the age of dinosaurs 6500-7000 years, even with dinosaurs for food!

The challenge of human "common sense" is found once released, triggering a series of questions at once: it really such a frog? It is what is magical ability, can escape this dinosaur ate a Big Mac?

Dinosaur eat frogs really much big?

Scientists mysterious frog named "devil frog" (Devil Frog), also known as "devil toad." It's the first pieces of debris found the fossil in 1993. After scientists fossil fragments collected enough level, it will only "combination." Paleontologists discovered "devil frog" of the State University of New York at Stony Brook Cross said it than those living in any modern frogs have large, probably the largest on the planet so far survived for only a frog.

The world's largest frog today is the only African giant frogs, which can grow to about 30 cm, weighing over 3000 grams. If it opened the legs, can grow up to 70-80 cm. But once compared with the "devil frog" frog giant African body would significantly very petite.

The study found that "devil frog" like a bowling ball as big, up to 41 cm and weighs 4500 grams. This nearly half-meter-long frog, as well as heavy head bones and teeth. With wide mouth and strong chin, something to eat something never eat slowly. Although the "devil frog} '" really fierce, but to say it can eat dinosaurs, still difficult to convince people, after all, in front of a huge ferocious dinosaur, it best be regarded as a "Little Dot."

However, the Institute of Vertebrate Paleontology and Paleoanthropology researcher, Chinese ancient animal curator Wang Yuan told continent, "Science and Technology Daily" said: "The devil frog should eat a dinosaur cubs or small dinosaur."

Back in 2008, scientists suspect that this "king frog" may baby dinosaurs for food. Evans said evolutionary biologist year to accept an interview with the BBC: "If it is offensive and learn ambush tactics, it will become a powerful predator of small animals, its food is likely to be so small by insects and lizards vertebrate composed. but the devil frog ate baby dinosaurs are also possible. "

Now this hypothesis has been confirmed by an international team of biologists University of Adelaide. Scientists believe that devil frog camouflage environment will be with grass, mud, etc. themselves, motionless staring at the situation around. If you see large animals pass by, they will "remain intact." If you run into a small dinosaur or lizard through, it will quickly attack.

Dinosaur eat frog just how fierce?

School of Biological Sciences researcher at the University of Adelaide Jones said in a statement: "Taking into account devil frog bite force and was living environment, it is absolutely possible to young dinosaurs for food."

Well, the devil frog how much bite force, scientists have thus confirmed its ability to make the dinosaur eat it? Because of this giant frog has ceased to exist, so the researchers had to pass through the existing analysis to calculate its approximate frog bite force. They conducted a series of experiments through a close relative of the devil Horned Frogs frog, combined with comparative information skeletal structure features two kinds of frogs, inferred conclusion.

It was found that the head width of 4.5 cm Horned Frogs small bite force has been able to achieve 30 "Newton" units, equivalent to 6 kg of weight. Other researchers estimate that in South America, found the giant Horned Frogs can use about 500 "Newton" bite force bite prey, the head size is close to 10 cm.

According to the analysis of prehistoric frog fossil jaws and teeth strong and calculation according to body size ratio frog, researchers estimate extinct devil frog bite force 2200 "Newton", which can be a powerful bite force comparable to mammals lion . 　

In this regard, Professor Christopher Rabin • California Polytechnic State University, said: "This bite force equivalent to 50 kilo grams of water placed on a fingertip to bring pressure." This is enough to make the devil frog hunting eating dinosaurs, though it may only hunt small size, weak constitutions of those dinosaurs.

The devil frog fossil found in Africa and Madagascar Island. Scientists said that although the devil frog living in ancient times, but it comes with frogs living in South America today is very similar. This proves that the island of Madagascar and Antarctica and South America have been connected.
