Fossil evidence shows that the longest crocodile to ever live was a sarcosuchus imperator, who was 40 feet long and weighed more than 1,000 pounds. Crocodiles are one of the most diverse groups of animals on the planet. They can be found in tropical and subtropical regions around the world, as well as in temperate regions such as the United States, Europe, and Asia.

How big did prehistoric alligators get?
Deinosuchus was far larger than any modern crocodile or alligator, with the largest adults measuring 10.6 meters (35 ft) in total length, its overall appearance was fairly similar to that of other crocodiles and alligators. It had a long, narrow snout, a large, flat head, and a short, thick neck.
The most distinctive feature of this species, however, was its tail, which was much longer than the rest of its body, reaching up to 2.5 meters in length. The tail was covered with a thick layer of keratin, the same material that makes up fingernails and toenails.
This made the tail extremely tough and resistant to damage, as well as allowing it to be used as a weapon. In fact, it was so strong that it could have been used to kill an adult human in a single blow, although it would have taken a lot of force to break through the skin of a human’s skull.
How did crocodiles survive the asteroid?
This is a great question, and many scientists have asked it. They lived in places that were the least affected by the asteroid. Crocodiles live in the tropics and subtropics of the world. Their diet consists mainly of fish, but they also eat small mammals, birds, reptiles, amphibians, insects and other invertebrates.
Crocodiles are the largest land animals on the planet, with a body length of up to 1.5 meters (5 feet) and a tail that can grow to more than 1 meter (3 feet). Their skin is covered with scales, which are made of keratin, the same substance that makes up fingernails and toenails. These scales are used to protect the crocodile from predators, such as snakes, lizards and birds.
The scales also serve as camouflage, allowing the croc to blend in with the surrounding vegetation.
Did crocodiles used to be giants?
Gigantism in crocodiles has been reported several times in the fossil record. The oldest evidence of giant crocodiles in North America is Deinosuchus, which is believed to have been between eight and ten feet in length. The largest known crocodile, Carcharodon carcharias, was about eight feet long (3 m). Crocodiles are not the only animals that can grow to enormous sizes.
Mammals such as elephants, rhinoceroses, and hippopotamuses have all been known to grow larger than their body size would suggest. For example, elephants are believed to be the largest land mammals on the planet, with a body mass of about 2,000 kg (4,500 lb) and a height of 1.8 m (5 ft) at the shoulder.
They have a trunk length of up to 2.2 meters (7 ft), and their trunk is about the same length as the trunk of a human being.
How big did prehistoric spiders get?
In 1980 paleontologist Mario Hunicken made a startling announcement; he had found the remains of the largest spider to have ever lived. This prehistoric arachnid was found in the 300 million year old rock of Argentina and appeared to have a body over a foot in length and a leg span of over two feet. The spider was named Araneus diadematus, which translates to “the giant spider” in Latin.
The spider’s body was covered in a thick layer of silk, and its legs were so long that they could have been used to climb trees. It was estimated that the spider weighed up to 1,000 pounds, making it the heaviest spider ever to be found in North America.
In addition to its massive size, the araneid spider also had a highly developed sense of smell, able to detect the presence of other arthropods in its environment, such as insects and other spiders. This ability allowed it to avoid being eaten by predators, as well as to hunt for food in areas that were otherwise inaccessible to it.
Did dinosaurs eat crocodiles?
The fossil was first discovered near Winton in 2010 and took more than six years to piece together. The first evidence that crocodiles and birds ate the same food was found in the remains of an ornithopod.
The fossil, which was found in a limestone quarry, is thought to have been part of a group of dinosaurs that lived in what is now South Africa about 65 million years ago, when the world was much warmer than it is today.
