吃：肉史前傳奇新生代，哺乳動物時代不是恐龍，而是史前傳奇

Titanoboa was the biggest snake that ever lived. It was longer than a school bus and heavier than a car. This giant snake lived in hot, swampy rainforests in what is now Colombia.1 2

這隻不是恐龍，但牠是史前時代最有名的動物之一，所以在 Dino Wiki 也有一席之地。

酷東西

趣味知識

Titanoboa was so big that it needed a very warm climate to survive. Scientists think the temperature had to be at least 30 to 34 °C (86 to 93 °F) all year round.2

The first Titanoboa fossils were found in 2002 by students from the University of Florida and the Smithsonian Tropical Research Institute. At first, scientists thought the bones belonged to crocodiles.1

Titanoboa lived right after the dinosaurs went extinct, about 58 to 60 million years ago. It was one of the biggest reptiles on Earth at that time.1 2

Scientists found bones from at least 30 different Titanoboa individuals in the same coal mine. This shows that many of these giant snakes lived together in the same area.1

Titanoboa had a skull and teeth that were good for eating fish. Its mouth was shaped like the mouths of modern fish-eating snakes.1

The biggest Titanoboa was about 12.8 meters (42 feet) long. That is longer than a school bus, which is usually about 11 meters (36 feet).1 2

關於 Titanoboa 最常被問的問題

?How big was Titanoboa?

Titanoboa was about 12.8 to 14.3 meters long and weighed around 730 to 1,135 kilograms. That is longer than a school bus and heavier than a car.1 3

?What did Titanoboa eat?

Titanoboa was an apex predator that likely ate fish, turtles, and crocodiles. Its skull and teeth were good for eating fish, similar to modern fish-eating snakes.1 4

?When did Titanoboa live?

Titanoboa lived about 58 to 60 million years ago, right after the dinosaurs went extinct. That was during the Paleocene epoch.1 3

?Where was Titanoboa found?

Titanoboa fossils were found in the Cerrejon coal mine in Colombia. This area was a hot, swampy rainforest when Titanoboa was alive.1 3

?Is Titanoboa a dinosaur?

No, Titanoboa is not a dinosaur. It is a giant snake from the boid family, which includes boas and anacondas. It lived after the dinosaurs went extinct.1

?Could Titanoboa swim?

Yes, scientists think Titanoboa was semi-aquatic, like modern anacondas. It lived in rivers and swamps and likely hunted in the water.1 4

?How did Titanoboa become extinct?

Nobody knows for sure why Titanoboa died out. It likely went extinct due to climate change as the Earth cooled and its warm rainforest home shrank.3

?What would happen if Titanoboa was alive today?

If Titanoboa were alive today, it would need a very warm climate, at least 30 to 34 degrees Celsius all year. It would be the biggest snake on Earth and could eat large prey like crocodiles.1 3

?How fast could Titanoboa move?

Scientists do not know exactly how fast Titanoboa could move. As a large, heavy snake, it was probably slow on land but faster in water, like modern anacondas.1

?Was Titanoboa bigger than a T. rex?

Titanoboa was longer than a T. rex, but not as heavy. T. rex was about 12 meters long and weighed up to 8,000 kilograms, while Titanoboa weighed only about 1,135 kilograms.1

迷思破解王

迷思： Some people think Titanoboa was a dinosaur.

真相： Titanoboa was not a dinosaur. It was a giant snake, a reptile that lived after the dinosaurs were gone.1
