The world's oldest reptile nest was identified in Arizona. Sixty-two bowl-shaped dimples have been found in the sandstone of Arizona's Petrified Forest National Park, and have been identified as hundreds of millions of years old, twice as old as reptile nests found in the past. The discoverer of the nests, Stephen Hashiotis, a consulting geologist at Exxon, pointed out that the nests were originally holes, which had been transformed into stones after a long historical process, and may have been made of crocodile-like reptiles such as phytosaurs and aetosaurs.

Other scientists point out that the discovery suggests that at least 100 million years ago, during the Triassic period, some vertebrates no longer laid eggs directly on the ground and protected their eggs in their nests. Hashotheis discovered the nests in 1996 when he was working as a research assistant at the University of Colorado. He said he had passed by the dens more than a dozen times and had never grasped their significance.

No eggs or eggshell fragments were found in these nests. If it's the biggest and oldest, it's the dinosaurs.

The largest animal in the world, weighing the equivalent of 25 elephants, can consume 2-5 tons of food per day; The largest animal in the world can weigh 50 people on its tongue and weigh as much as 25 elephants.

The largest animal in the ancient world was the Argentinosaurus. Argentinosaurus is one of the largest land dinosaurs found so far, and it is a dinosaur found in Argentina. It can reach a length of meters and an overall weight of up to 100 tons.

These dinosaurs were huge, with a single vertebra capable of reaching four feet. They live on the shores of forested lakes, which are abundant in water and food, and many large sauropods live.

Argentinosaurus excavationsFossil Argentinosaurus bones have been excavated with a meter-high dorsal bone, as well as pelvic and hind limb bones, and although the Argentinosaurus is similar to Brachiosaurus, experts believe that it still belongs to the Titanosaurus family. They live on the shores of forested lakes, which are abundant in water and food, and many large sauropods live.

The prehistoric megalodon was 20 meters long and weighed more than 70 tons.

The megalodon is an average shark that is 14 meters long and weighs 40 tons. Some of the vertebrae of the Megalodon have been found to be much larger than those of the Great White Shark, and it is speculated that its maximum length range is 18 meters, and it weighs 50 70 tons, making it one of the largest predators ever recorded, as well as the largest fish, but no complete vertebral skeleton fossils have been found to support this hypothesis.

Megalodon is perhaps the most powerful creature ever found in Earth's history, with a maximum bite force estimated to be around 20 tons, and its oral bite power exceeds that of a Tyrannosaurus rex, allowing it to crush whales' ribs with ease. Living from the Late Miocene 15 million years ago to the Early Pleistocene 2.6 million years ago, it was the apex predator of the ocean. They have been hailed by many paleontologists as the most powerful creatures in the history of the planet.

Megalodon habits

Megalodons lived in the vast ancient oceans and were the apex predators of the oceans during their lifetime. Megalodons can hunt any creature in the sea, but they prefer to hunt cetaceans the most. Other marine mammals are also on its plate.

Adult megalodons hunt in the open ocean, while juveniles live closer to shore. Megalodon had no predators at the time, only rivaled by Melville's whale, which was also an apex predator.

A giant shark that lived between 28 million and 1.5 million years ago was once widely distributed based on the scars caused by megalodon attacks on whale fossils found in various places. Currently extinct, the extinction of the megalodon remains an unsolved mystery.
