The T-Rex would win a fight against the largest crocodile ever. Simply put, the T-Rex is just too large and powerful for the crocodile to kill. Sarcosuchus imperator certainly had a powerful bite, but those 6-inch teeth aren't going to puncture the T-Rex's vital organs or cause it to bleed to death from a single bite.
Dinosaur Hunters
Crocodiles as long as school busses and as heavy as elephants roamed the Earth as recently as 8 million years ago. These massive crocs tackled some of the most ferocious prey around: dinosaurs.
This enormous predator had jaws powerful enough to subdue massive dinosaur prey. An enormous Cretaceous crocodile relative hunted dinosaurs, ripping them apart using powerful jaws lined with teeth "the size of bananas," researchers say.
A hippo would win a fight against a crocodile. Although crocodiles are large, powerful creatures, they cannot kill a fully-grown hippo. Hippos are large, round animals that are much taller than crocodiles. The only place they would be vulnerable to attack is their legs.
The freshwater crocodile, named Confractosuchus sauroktonos, which means "the broken dinosaur killer," was over 8 feet long. But Matt White, research associate at the museum and lead researcher, said it would have grown much larger. Researchers were unsure how the crocodile died.
Sixty-six million years ago, dinosaurs had the ultimate bad day. With a devastating asteroid impact, a reign that had lasted 180 million years was abruptly ended. Prof Paul Barrett, a dinosaur researcher at the Museum, explains what is thought to have happened the day the dinosaurs died.
They existed long before our time, and there are no dinosaurs left today. There are a lot of interesting and fascinating facts about dinosaurs that have been presented in movies and articles about them.
But despite their size and strength, there are animals that do prey on them. Man appears to be their biggest predator. Big cats like leopards and panthers sometimes kill and eat these big reptiles. Large snakes can also do a lot of damage to alligators and crocodiles.
The T-Rex would win a fight against the largest crocodile ever. Simply put, the T-Rex is just too large and powerful for the crocodile to kill. Sarcosuchus imperator certainly had a powerful bite, but those 6-inch teeth aren't going to puncture the T-Rex's vital organs or cause it to bleed to death from a single bite.
So crocodiles are not dinosaurs, ancient crocodiles were around before most dinosaurs. They survived the extinction event (like an asteroid) 66 million years ago and are still alive today.
The study also revealed that the bite forces of the largest extinct crocodilians exceeded 23,000 pounds, a force two-times greater than the mighty Tyrannosaurus rex.
Australia has two species of crocodiles, the saltwater or estuarine crocodile, Crocodylus porosus and the freshwater crocodile, C. johnstoni. Readable and well-illustrated reviews of the biology of world crocodilians may be found in Webb & Manolis (1989) and Ross (1989).
So, are chickens dinosaurs? No – the birds are a distinct group of animals, but they did descend from the dinosaurs, and it's not too much of a twist of facts to call them modern dinosaurs. There are many similarities between the two types of animal, largely to do with bone structure.
In fact, birds are commonly thought to be the only animals around today that are direct descendants of dinosaurs. So next time you visit a farm, take a moment to think about it. All those squawking chickens are actually the closest living relatives of the most incredible predator the world has ever known!
A crocodile would win a fight against an unarmed human.
An average crocodile that weighs 700 pounds and measures over 10 feet long is going to be too powerful for a human to overcome.
Although the lion has a lot of advantages over the crocodile in terms of a fight, the crocodile would win in a fight against a lion. The crocodile is simply too large and powerful for the lion to defeat.
"Lions are wary of crocodiles and will generally avoid the water to stay away from crocs," writes NatGeo TV.
If there is one animal that could bring down a full-grown hippo in a fight, it is an adult elephant. Elephants have the size and strength advantage over the hippo, and their tusks give them superior reach. Match that with a roaring charge and there is nothing that will not stop one!
Lions have few predators to fear other than humans. A very young or sickly lion might fall prey to hyenas. Cubs may be attacked and eaten by adult male lions. Lions are most threatened by humans who hunt them and encroach on their habitat.
The cause of tears in crocodilians is unclear. Apparently they hiss a lot while eating and so something to do with sinuses might be activating the tear glands. But they also shed tears just from being on land for a while, whether or not they are eating.
In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
The results of this study, which were based on estimated real global biodiversity, showed that between 628 and 1,078 non-avian dinosaur species were alive at the end of the Cretaceous and underwent sudden extinction after the Cretaceous–Paleogene extinction event.
Bizarre 500-toothed dinosaur
Nigersaurus, you might remember, we named for bones collected on the last expedition here three years ago. This sauropod (long-necked dinosaur) has an unusual skull containing as many as 500 slender teeth.
