How crocodiles lived for 200M years and outpaced the dinosaurs

Today’s birds evolved from dinosaurs. Man evolved from fish. But crocodile? They remained from the beginning to the last.

New research by UK scientists at the University of Bristol provides evidence that the powerful crocodile has existed for over 200 million years, destroying dinosaurs and countless other plant and animal species, erased by an asteroid Those that had collapsed in the Yucatan Peninsula. 66 million years ago.

It is his environmental versatility and physical efficiency that has allowed him to survive mass extinctions and two ice ages.

The study’s author, Max Stockdale, said, “Crocodiles embarked on a lifestyle that was adapted to broader environmental changes, adapted to the ongoing environmental changes of dinosaurs.” “This could be an explanation as to why crocodiles survived meteorite impacts at the end of the Cretaceous period, in which dinosaurs worsened.”

Unlike most animals, crocodiles thrive in both terrestrial and aquatic ecosystems, with their ability to breathe for up to an hour. They do best under warm conditions, as cold-blood reptiles depend on external factors for thermoregulation, and can survive for months or years without food, drawing energy from the sun and eating less while they eat their next meal.

Their bodies are rigid and rigid, designed to sustain significant injury. In fact, it is not uncommon for an area to lose its foot in a fight, then to live a long life of between 70 and 100 years.

According to new research published in Nature Communication Biology, crocodiles have gone through evolutionary changes, but their changes have occurred in the form of a “stop-start” pattern, in which extensive stroke changes for the species occurred in more favorable ecological conditions.

“It is interesting to see how deep there is a connection between the earth and the living things shared between us,” Stockdale said.

For example, the warm climate during the age of dinosaurs was the perfect place to grow a wide variety of crocodile types: giant crocodiles, herbivorous crocodiles and snake-like sea crocodiles to name a few. These special editions eventually gave way to today’s more well-organized species, which is why they have been dubbed the “last survivor”.
