Crocodiles are called living fossils, looking much the same as they did millions of years ago. The first crocodile fossils were from the Triassic period about two hundred forty million years ago. They came before dinosaurs but from the same group. This group included crocodiles, pterosaurs, and dinosaurs. Fossils worldwide help us know what some ancient crocodiles looked like and their behavior. Structure Of A Crocodile   Crocodiles have powerful jaws with sharp conical teeth and tiny legs with clawed webbed toes. They have a rare body structure that allows the eyes and nostrils to be above the water's surface while...

Pachycephalosaurus is one of the unusual dinosaurs found in the fossil deposits of North America. They came under the genus of enormous dinosaurs that existed around the Late Cretaceous Epoch era about 100 million to 65.5 million years ago. Pachycephalosaurus are known to have a helmet head that saves them from any injury. They were usually 5 meters long with strong hind limbs. Further, scientists used to speculate that Pachycephalosaurus fossils have partially developed forelimbs. Pachycephalosaurus are known for their highly distinctive features like dome skulls made up of thick solid bone covering the tiny brain. However, the bone growth...

Triceratops is among the large quadrupedal ceratopsian dinosaurs that generally eat the plant. It is among the most famous dinosaurs among children after Tyrannosaurus because it has three horns on the skull. These magnificent creatures used to live in the final stages of the Cretaceous Period. Further, as per the exact time frame, it has been speculated to live around 145.5 million to 65.5 million years ago. Thus, they are one of the last avian dinosaurs ever to walk on the earth. After studying the Triceratops fossils, paleontologists speculate the creature's body length is around 30 feet (9 Meters). Moreover,...

Basilosaurus, known as the "king lizard," is found in the late Eocene, which is about 41.3 to 33.9 million years ago. It is the classification of predatory, big, and archaeocete whales, depicted in 1834 and known as the first prehistoric whale discovered by science. The "Saurus" in their name is because of the giant size of these reptiles.  Later, scientists discovered it was an early marine mammal by studying its fossils. The very first fossil of type species B. cetoides was discovered in the United States. Later the species, B. isis was found in Jordon, Egypt, Morocco, Western Sahara, Tunisia,...

Crocodiles are large semi-aquatic reptiles inhabiting the tropics in Africa, Asia, the Americas, and Australia. All current members of the order Crocodilia, including extinct taxa such as the gharial and false gharial (family Gavialidae), alligators, and caimans (family Alligatoridae), are frequently referred to as crocodiles. The first crocodilians, reptiles, originally arose about 320 million years ago. The amphibians, a diverse group of animals at the time, were the immediate ancestors of reptiles. The gharial is easy to detect due to its short snout, whereas crocodiles and alligators have more subtle physical characteristics. These features could also be seen in the...
