A "high fever" 55 million years ago, the earth created the largest snake in history: Titan python

In 2016, a 300-meter-long giant python was found in the Red Sea area. It is said that after the python made waves in the local area, 540 innocent people were killed. In the end, the local government dispatched planes, tanks and armored vehicles to kill it. This news was spread with nose and eyes back then, and it was more thrilling and exciting than the disaster film "Disaster of the Wild Python", but it was later confirmed that it was an eye-catching fake news. However, 55 million years ago, due to the substantial warming of the earth, the largest snake in history actually appeared in South America. It was huge in size and had an amazing appetite. Even the largest beast in South America would detour when it saw it. How big is it? How was it born?

The Titan in the Coal Pit:

This historic basilisk is the beast that dominated the earth in ancient times - Titan Python. In 2002, paleontologists discovered a large number of paleontological fossils in the largest coal pit in Colombia. These fossils showed us an unknown prehistoric world: giant plants, ancient fish, giant coal turtles... (Columbia Coal The most shocking among them is the Titan python fossil, because paleontologists found by looking at the fossils that the Titan python is actually the largest snake animal in the history of the earth. How big is the titan python? They can be up to 15 meters in length, and their upright height is close to a 5-story building. Although it is not as exaggerated as 300 meters, the weight of the Titan Python has reached an astonishing one ton! This keeps it at the top of the food chain, and makes all kinds of mammals scared to go around with their tails tucked. 55 million years ago, Titan pythons lived in the lush tropical rainforest in eastern Colombia in South America. As a local top predator, in order to reduce the pressure of body weight, Titan pythons lived in water most of the time, so their The food is also top quality seafood. In the eyes of the Titan Python, there is no aquatic product that cannot be eaten, regardless of the ancient crocodiles and giant coal turtles, they are all appetizers. When they hunted, they lurked at the bottom of the water. When the crocodile was swimming in the water, the Titan Python jumped up and suddenly attacked the crocodile that was more than 4 meters long. Of course, the hunting method of the Titan python also gives full play to the talent of snakes for strangulation. They will tightly wrap around the prey. When the prey is completely broken and dead, the Titan python will open its bloody mouth and enjoy it to the fullest. The terrifying appetite of the Titan pythons can't help but make people sigh: Fortunately, they became extinct as early as 58 million years ago. If the Titan pythons are still alive, I am afraid that humans will suffer. So the question is, it is also a wild python, why is the current largest snake, the anaconda, only 4 meters long, while the prehistoric giant beast, the titan python, can grow to 15 meters long?

Eocene extreme heat event, giving birth to the Titan Python

About 55 million years ago, the earth's average temperature suddenly rose sharply, soaring by 5-8 degrees Celsius, then When the average temperature at the equator is 38 degrees, even the north and south poles where glaciers are spread have become an oasis. The earth seemed to have a high fever, and this high fever lasted for 170,000 years. This historic global warming is known as the Paleocene-Eocene Extreme Thermal Event Period (PETM). (Extreme Thermal Event Temperature Demonstration) So, what is causing the sudden warming of the earth? In this regard, geologists from the University of Oslo in Norway pointed out that the root cause of this global warming is not the atmosphere, but the ocean. The geologist speculates that in the mass extinction 65 million years ago, when the volcano erupted, the volcanic ash on the seafloor mixed with the carcass of marine life, resulting in a large amount of methane crystal deposition and conversion into gas, and the seabed emitted excess methane gas. In water and in the air, this greenhouse gas, which is hotter than carbon dioxide, is responsible for soaring temperatures on Earth. (Changes in seafloor sediments) And in this global warming, warm-blooded mammals suffer. Warm-blooded animals have a set of temperature regulation mechanisms in their bodies in order to adapt to the changes of the four seasons, but during the Paleocene-Eocene extremely hot period, 365 days of the year are summers with a high temperature of 38 degrees. This keeps the heat in the body of the warm-blooded animals from dissipating, and they die from heat stroke. In particular, the larger the warm-blooded animal, the faster it will die. On the contrary, ectothermic animals (cold-blooded animals) are extremely fond of hot weather, and each grows fat and strong. For example, when the ambient temperature is higher than the body temperature of the python, they will stretch their bodies to increase ventilation, which can accelerate heat dissipation. Therefore, when the temperature is higher, the body of the python becomes larger. Invisibly, the Titan python has gradually evolved from 4 meters to a giant python of 15 meters. This is also the famous Bergman's law. In the Paleocene-Eocene era of extreme heat, this law allowed the Colombian rainforest to grow coal turtles the size of SUVs, and crocodiles that were longer than ordinary living rooms. Of course, they No matter how big the body is, it is not as big as the Titan Python, and finally it becomes the appetizer of the Titan Python. (SUV-sized coal tortoise) But this also raises new doubts, why did the Titan python that exists like a mountain go to extinction?

Why did the titan python go extinct:

The scientific community is still inconclusive on this question. However, the more generally accepted statement is that the Titan python was "not born at the right time". The Paleocene-Eocene extreme heat has only existed for 200,000 years in the long history of the earth's evolution. When this extremely short period of earth's high temperature passed, the excess methane on the earth slowly dissipated, and the earth's temperature gradually increased. Cool down. When the earth returned to the normal temperature with four distinct seasons, the ancestors of human beings, primates, began to evolve, and the temperature-changing animals like the Titan python, because of the lack of hair to deal with the cold, had to hibernate all day long in order to cope with the long cold winter. Getting smaller and smaller, it turned into a 4-meter-long anaconda in the Amazon rainforest today. The Paleocene-Eocene extreme heat era also sounded the alarm for human beings. Scientists calculated that it would take about 44 trillion tons of carbon dioxide to usher in the extreme heat era, and now human beings around the world emit about 36.7 billion tons of carbon dioxide every year. With the rapid emission, it will be inevitable for mankind to usher in the second extremely hot era of the earth. As a warm-blooded animal that cannot dissipate heat, it is unrealistic to want to grow into a Titan python, then extinction will be the only destiny of mankind.

Written at the end:

The survival of the fittest and the survival of the fittest in nature is so cruel, so even in ancient times, the Titan python has become a fossil and History, is exhibited in the Natural Science Museum. And for all this, the earth has never said a word, looking down at the thousands of ants on the vast land with indifferent eyes. Just like looking down at the dinosaurs 100 million years ago, the Titan python 55 million years ago, it is very likely that we humans will be next. The extinction and evolution history of the earth has taught mankind a vivid lesson. References: [1] Yan Feiyun. The Eight Ancient Titans Python
